Ford F150 One Piece Driveshaft Slip Bump- FIX! 

I can’t say thank you enough. I’ve had my truck for 10 years and it has “bumped” from day one. Everyone just said, “Yeah. All F150s do that!” Well....not anymore. My 2005 F150 XLT drives smooth as can be now. I would have sworn that the rear differential was shot...but nope. An $18 kit, and about an hour of my time was all it took. THANK YOU!

Holy Shit! I finally know what's wrong with my truck! I've been dealing with it for years now. I tried googling when it first started, but found nothing. Man, thank you SOOOOOO much.

You better be the highest paid Ford Tech in the country!!! Your a Legend!!!! Props to you! I greased my shaft and its fixed!

Thank you for this video... I went to a mechanic that estimated in $800.00 to fix the noise, he said it was the deferential... another mechanic said he had a pick-up truck with the same problem, he sold the truck because he could't find the problem... I saw this video, I've done the same and my pick-up truck now is fixed, it is like miracle... Just grease, I spend only $10.00 .

For months MONTHS no mechanic could figure out what that annoying ass bump was. They all said the same thing "it's a common ford issue" until I saw this and tried it myself. I must say...you're the man! I'm in love all over again

Thank you for taking the time to make this. I bought a 2010 FX2 with the 2-piece driveshaft and 67,000 miles. About 3 weeks later I started experiencing the super annoying clunk whenever I accelerated and stopped. I thought it was the transmission at first shifting hard but then realized the RPMs didn't change when it clunked. Got the shaft repair kit you mentioned on eBay for $17 and man what a difference. Took me 45 minutes and the truck drives smooth as butter now. A huge relief knowing that's all it was.

2010 f-150 Platinum. Drove with that for over a year! Man i wish i found this video a long time ago. 20 mins and i fell in love with my truck all over. Thank you so much!!!

8 years later after making this video, it is still helping people. I had it in my head there was too much slop in the transfer case or the trans mount was bad. Mine was clunking hard. I had just replaced the driveshaft not long ago and just couldnt imagine that could be a problem. Sure enough the splines were dry as hell and greasing it completely fixed the clunking. Thank you.

Your wording is impeccable bumps that aren't there or shifts, I couldn't of thought of a better way to explain it myself well done

This worked on my 2016 FX4 SuperCab with one piece driveshaft. Noticed this issue when I bought my truck used in August 2023 and was racking my brain trying to figure it out. I thought it just had play in the ring and pinion until finding this videos. Thank you for posting this. So, to those with newer trucks this issue continues to be a problem and this solution continues to fix it. I just used some blue grease I already had in my grease gun. Feels like a new truck now. Thanks again!

Unbelievable that something this simple was worrying the hell out of me lol. Thanks for the video, just serviced my truck and it feels like a new truck again!!

Had this exact issue on a 2013 f150. Went to ford and picked up a tube of the grease you linked in your bio. Put it in this morning and the issue is gone. You’re a life saver dude! 🙏 People we bought from told us they were quoted 3-4000 to fix the noise

Yessss! I could not figure this out for the longest time. It was really bothering me. Put it up on the lifttoday at work, pulled off the drive shaft, greased the splines, and no more binding when pulling off from a complete stop! It feels good. Thanks for this video!!!

Thank you so much for this video. I took my 2014 F-150 to a shop and they told me I needed a new rear end, would cost between $1800-$2500. Watched your video this morning stopped by Auto Zone and $12 later I have no bumbling when I start and stop. Thank you again.

I have a 2010 with the two piece drive shaft that had this problem and you aren't exaggerating one bit on how horrible and annoying this problem is. It made me hate and want to get rid of my truck. My local dealer fixed it using the method you showed under warranty and the drivetrain feels nice and tight now. I'm back to loving my F-150. Thanks for posting this. I know this problem has been going around the forums for years.

Your video was extremely helpful. I replaced the bolts with new as a precaution for $10. I read that others had issues with chocking the rear wheels. I used 4x4 pieces of wood and plastic RV chocks to secure the wheels. Thanks for making this video, you’re the absolute best.

I'm having this issue again on my 2006 F150. In 2016 it started so I took it in to a ford dealer. Paid $351 for the repair. I recently started noticing that thump again. Thanks for the video.

You are the man when it comes to Ford. I wish my local shops had someone as knowledgeable.

I wish you lived in Houston. A tech that actually fixes vehicles. Ford needs more employees like you.

For the longest time I thought it was the transmission issue and was waiting for it to finally go out. But turned out to be this issue on my 2010 Ford F150. What a huge difference it made. Truck drives like new now.

So glad I found this video! 20 minute job, that has made such a huge difference!

I installed a new driveshaft from a-1driveshaft within 3 weeks bump and slipping like you said,used this lube and works like new Thanks Ford tech again

Had the bump that was driving me nuts for a few months now. I was skeptical but this fixed it. 🙌

Thanks Brian. I seem to be experiencing the 'bump' in my 2017 F150 with the one-piece drive shaft. Really started noticing it after dropping the rear differential cover and changing fluid. Wondered what the heck I could have done!? Now, it seems it may be 'what did Ford do?'. 🤨 I'll be pulling this soon and greasing it up. Update: Got my 12-Point 12mm socket, Blue Thread Locker and Blue PTFE lube today. Lubed my shaft, went for a drive . . . no more 'Slip Bump'. Thanks again!

Just did my Excursion. Wow. What a difference. Thank you so much for taking the time and making this video.

Awesome video! This fixed the rear end bump upon starting from a stop in my 2011 f150 lariat 5.0 super crew!! Such an easy DIY fix.

Awesome just saw the video and jumped under my truck to fix it. My truck now it's so smooth. Thx buddy

My 2020 F-150 2.7 4wd did this. The grease fixed it. Easy job.

Im glad I found you, so much useful info for my 2013 f150.91000 miles. Boy do I have my work cut out for me. Thanks for all your help.

THIS WORKS!!!! Thank you we have been trying to figure this out for a year, we thought maybe torque converter , differential, or transfer case.very easy fix, took about an hour and $4 for grease

Fell upon the newer video with the 2 piece driveshaft, so found this one today... My 2010 4.6L was doing this and I never thought it would be this... I’m going to double check to see if mine is a 1 or 2 piece, which I figure the repair numbers are probably the same, and fix mine... Thanks for your help and knowledge of the Ford Trucks and passing it along to the rest of Us.. 👍🏼👍🏼👍🏼☮️

GM had this same issue years ago. I did hundreds of them. Same thing....they had us grease the slip joint as a band-aid, and that didn't fix it, in the long run. Replacing the slip yoke with the heavy nickel plated yoke did fix it.

Thank you for this video, I used this information to repair my two piece drive shaft '12 F150 2wd lariat. No more bump! I appreciate it very much!

THANK YOU!!! I have a 2010 with the single shaft and this issue just started a couple days ago. I've been having my bed weighed down with debris from construction and alot of stop n go with pretty abrupt stopping. You sir are a godsend!

Your advice is spot on I am handy capped so it makes it easier for me to to check on your site to help me figure out what's going on with my 2013 f150 question explain TSB reports and how they effect the consumer, thank you .

I want to thank you for your video. I also have a 2010 Ford F150 King Ranch love the truck except for that horrible slip/bump noise drives me crazy. So last week I jacked my truck up and remove the drive shift myself and with the kit you requested loaded that puppy up slap it back together and it now drives like a brand new truck. Please keep up the great work you did GOOD!!

2005 F150 Super Crew Lariat with the one piece steel drive shaft. This started happening to me, and the truck stranded me in the middle of a busy intersection. The drive shaft broke in half! Had to drive it home in 4x4/front wheel drive. Make sure to keep these yokes greased with the PTFE/Teflon grease! Got mine back on the road after jumping threw a few hoops finding a good driveshaft.

I dont normally comment, but in this case I have to. You are the man!!!! You have helped me fix 2 issues with my 2010 F-150 now. this problem as well as the issue with the heat shield. Thanks, and much appreciated!!!

outstanding mechanic and great style of presentation, very competent and professional, thank you

Thanks for this helpful video. Did this procedure to my 18 2.7 Scab yesterday and the 2 piece drive shaft looked a bit different. The splined section that came out of the rubber boot was like a foot and a half long with wide splines. It did have some grease but I added quite a bit more. It helped somewhat with strange clunks when slowing to stop.

2021 and they still haven't properly fixed this. 36,000km on my 3.5 eco and taking it in in two days to have this fixed. Took the service manager out for a test drive with it to show him and he confirmed that's most definitely the issue.

My ranger just started doing this, amazing how quick it went from nothing to clunking everytime i touch or let off the gas. Took out the driveshaft and pumped er full of grease and shes back to her smooth self.

Also, if reusing the old driveshaft you need to take a file & file off burrs @ the start of the spline @ the front of the insert where driveshaft spline first slides in. This is what causes it to try to grab/stick. Then grease as shown & re-install/re-stab driveshaft.

Just ordered this stuff for my 99 Sierra. That slip bump is most noticeable when taking off. Actually bumps twice, kinda like someone gave you a love tap on your rear bumper. Hope it works! Thanks for the video!

Man thanks so much! My ‘11 has been doing this for several years since I bought it. Question: will regular bearing grease work? Thanks!

My 2011 raptor had the driveshaft replaced to fix this problem but it only worked for a couple years. Adding the grease fixed it for about 6 months before it started sticking again. I’ve seen fixes where the shaft was drilled for a grease fitting to make it easier to add grease without removing the driveshaft. Removing the driveshaft without a lift in your garage is a pain.

ptfe is slick stuff but if anyone wants to set it and forget it awhile, use full synthetic marine wheel bearing grease, stalube blue is the best

This goes back, way back into the laste 90's. I have an 02, F150 long bed with 320k miles that is set up with this aluminum one piece drive shaft. Buying a new drive shaft is a $350 pricetag, but simply greasing it is what I do from time to time. And if its a bit worn that just gives a place for the grease to be without drying out too quickly as you tend to push most of the grease out with that chroming new and a super tight fit. Chroming or not, its a darn spline joint... grease it.

Just did mine and holy crap, my truck feels 1000 times better, thanks

Sounds like the same problem that GM's have had for a couple of decades.

Thank you for this Just bought a truck and thought it was the rear differential. Easy fix .

Just wondering if this solved your problem permanently or just temporarily. I will be doing this within the week but a lot of forums are saying that this only works for a few hundred miles and then the grease breaks free from a poor seal and the problem reoccurs. Thanks and great video!!

I had something similar on my '03 4x4 Ranger. It also has a one piece aluminum driveshaft....got the good ford tube of the same grease and it's been good for several years now. I originally thought it was a u-joint but ended up being this exact same issue.

I have a 1998 F150 and a 2011 Expedition. I enjoy your videos.

Same thing was happening in my Ford Lincoln '96 Towncar I just thought I must of had a cat hiding in the wheel well or something and it was falling out and getting run over... but I always saw no guts on the wheels and no one knew what that noise and bump was now I know it was the drive shaft doing this... thanks man... if you guys want to not have this problem get a Toyota or a Lexus much better car

Where is this genius's shop? I bet he doesn't have any lack of customers. Maybe repeat customers are lacking, but that would be a good thing! I'd bring my F150 to him in a heart beat. I'm having noise issues and these videos have been great!

Thanks for all your Ford videos. Got a lot of Ford coming in the the shop and there always a mystery.

Thanks man I couldn’t figure out the source of my clunks and this solved it, may end up replacing the slip yoke in the future if it acts up soon

Thank you,thank you I just did my F-150 2010 two piece drive shaft and it's the best now.thank you again.

Thx for all of the thorough videos. Very helpful to everyone watching. Keep it up. 👍

Thank you for spending so much time learning all the knowledge you share. I am grateful for your expertise and great videos.

Where did you order your new drive shaft from? I’m having a hard time finding one

"Internet gold" - works for my 2021 as well. I had the same "clunk".

I was amazed to.lesrn about the dry spline "thud" Had emptied my bed, checked ujoints and.transmission mount Bout ready to start disassembly front to back

I'm repairing the universal joints on my 2001 F150 SCREW 4.6 RWD. Should I use the lubricant inside the splines before I reinstall my one piece aluminium drive shaft? By the way I watch your videos constantly! I would love to work on your shop just to gain some knowledge from you so the videos are the closest thing I can get to that alternate reality! 😄

Brian, I have a 2009 F150 4.6L 6r80 trans with the two piece drive shaft but both ends are Flanged so there's no slip joint going into the Trans tail housing. Am thinking that since there's a flex boot at the carrier bearing that's the spot i need to add the new grease. Sound right to you? Because of your really great videos and the way you walk thru us through the repairs I had the confidence to tackle all of the upkeep repairs on my truck. Thanks Huge for all you do!! Really awesome. So far, after re-watching your repair videos to get my head on straight. With my son's help we have managed to replace all of my shocks/struts, transmission oil/filter and new adapter, spark plugs and coil packs. Little bit stuck on the drive shaft upkeep (bump and stick issue - big issue for me) and need a tad bit of your wisdom. I bought the white Teflon repair kit that you showed in this video. Because i wasn't 100% about the driveshaft I didn't take it apart when i did the other repairs. Realize this repair is a no-brainer for you but i am like i mentioned a tad concerned and really do want this bump issue fixed right. I do have an extended warranty on the truck but it expires this year and have only used it to replace the windshield when i bought the truck new. It had bubbles in the glass from the Kansas plant. Please help here -- Should i warranty the driveshaft to fix the bumping issue on my '09 pickup w/about 50K miles. It's not drastic mind you, but really freakin annoying. Thinking about the poor plating FOMOCO found and you mentioned. Am I right about where the spline is (at the carrier bearing) ? I'm kinda comfortable doing it but it's hard the son's gone back to the mainland and I'm handicapped. It would most likely be an all day task for me. Don't quite bend like when i was younger. Can i get from you the TSB or Recall numbers to show the dealership for the driveshaft for my truck? Do you want my VIN # ? The dealership isn't the most friendly at giving out info and acknowledging there's a repair TSB Recall out there. They tried to make me pay $150 to grease the wheel bump stops. Who knew that i needed to a dab of grease there every so often. It's listed in the repair books or service warranty. Questions - Am I right about where the spline is (at the carrier bearing) ? Can i get from you the TSB or Recall numbers to show the dealership for the driveshaft for my truck? Do you want my VIN # ? Sorry for the length of this and keep on truckin - You Rock.

I have an 03 that does this , sometimes I can fill it when it downshifts do you this could be the same issue. You have answered a couple questions for me in the past, I greatly appreciate your help

got a 2012 FX2 and this is driving me crazy lately. Going into Ford service tomorrow. If they want to charge me too much I will order kit. Thx

Just did this job. Worked well. Only thing when I took the drive shaft out of the transfer case, oil leaked out. I was slightly down hill.

Thanks for the vid, I agree it's horribly annoying. I just ordered the lubricant you posted and will give it a shot.

it actually happens in older ford's all the 90s probably until then but it's not nearly as bad because of the added knuckles in two piece shafts... I can't remember a truck growing up my father not putting a zerk fitting in by the spines. driving a truck that didn't have grease all in the splines was like pulling up to a red light soon as you came to a stop it feel like someone lightly banged your bumper with a fist .👊🏾and when u take off a light 👊🏾 only ocd people probably even know what I'm talking about 🤣

my 89 f150 does that exact thing. drives me nuts. I will try this. easy enough, and if it turns out to be the rear end, just spent a little time and some grease.

Bungee cords or 550 cord is great for fixing ujoints....you dont need to drop the drive line....just tie it up.

My truck started having the same slip bump issue but after driving for a while the corrosion actually provided something similar to a dry lubrication and it stopped doing it on its own.

This problem isn't new to me. I wish I'd heard about it before. It drove me insane for 15 yrs in a 1995 jeep Cherokee and later the same problem followed me on 1999 E 150. Shops and dealers didn't have a clue. I'm an industrial tech. I learn things daily and so do they, in sure. I corrected this issue purely by accident. It was until I watched this video that came to realize. . I had learned to ignore it.

I’m going to have my truck done tomorrow hope it fix this problem thanks man 🙏🏿👍🏿

Thanks for the great video! Planning this for next weekend as I now have this issue on my 2012 super crew f150. Question for you: I was under the truck tonight, before I saw your video, trying to see if anything was "loose". I noticed that I could move the out put shaft on the transmission had close to an 1/8" of play all around when I grabbed the shaft and pushed and pulled on it. Is this a normal amount of play? Thanks for all responses!

The biggest problem is Ford does not doing any testing done and releases the vehicle way too early.I don't even torque down the 4 driveshaft bolts down using the German torque spec using an impact.

I did mine last fall. White grease FTW. Replaced the U joints while I had it apart.

Thank you for the information I'll be doing this exact procedure on my 2004 F150 with the two piece driveshaft​ also thank you for listing the necessary parts.

In most peoples experience here with this fix, would you say that it fixed a problem only when starting and stopping, or would you say it fixed an issue going into a certain gear? I'm having my issue mainly going into 2nd gear where it usually slams into it hard. I found this fix, but I'm skeptical if it will work. It's $40 of tools and lube, so not a huge investment, but just wondering if anyone else out there had the same issues and solved it with this fix?

Dang, wish I would have seen this earlier. My 2016 did the slip bump at stop signs too. Most notably when it was a rolling stop or very quick 1 sec stop. I searched all over for this issue and could never find the fix. Dealer didn't have any solutions either. I got so fed up with it, and the supercab door rattle that I ended up trading it in for a 2018 supercrew. If I could have fixed this I probably could deal with just having the door rattle.

My 09 had this. My impression was a hard downshift or once I looked back to see if someone tapped me in the back when I stopped. Since it is slipped into the transfer case having lube oil in it , why does it even need lube? This doesn't say much for the lubrication properties of the thin trans fluid thats now used vs the old gear lube models.

You great at explaining something! Thank you!

I got 2012 f150 XLT runs on E85. My dash vibrates when i hit 70 miles per hr and up . i got good tires no bumps . roters are good . i got new shocks . what the heck can it be ? Ty man

Problem solved. Thankyou sooo much!! Fixed my 2010 f150

I am a retired chevrolet mechanic and when I rode in a ford truck a friend of mine has, the bump felt and sounded like a broken transmission mount to me. Yes I know the gm trucks have a problem with a clunk also. I am not picking on ford products ok.

Would Permatex PermaShield Fuel Resistant Gasket Dressing & Flange Sealant or Permatex Form-A-Gasket No. 2 Sealant or Permatex Aviation Form-A-Gasket No. 3 Sealant Liquid be a good idea to use at the end of the spline shaft opening to prevent water and dirt from entering these spline mating areas and contaminating the lubricant you recommended? As always you're the best, Bro!

I know this is an older video, but had a question regarding a 2013 150 4x4 with the one piece shaft. I added a 3” block to the rear in place of the stock block and now I have this slip bang again. Was curious if you think the fix would be simply to re-grease or to add a 3/4 drive shaft spacer? I know I changed the angles by adding the blocks, but what I don’t know is what the tolerance is for allowable “free play” on the yoke to the output shaft. Basically how far should it slide in and out under factory spec? Thanks, your videos are always a huge help!

Outstanding video, just did this to my 14 F150, works great!

Hi, I have a 2004 f-150 fx4 4x4. I installed a leveling kit and bigger tires, now I have a clunk or bump feel on take off and sometimes on braking. I have a one piece drive shaft that goes into the transfer case back to the rear. Do you think I have have to grease the slip yoke and is it possible since the slip goes into the transfer case? Thank you

Hello I have a 07 F150 and it has a 2 piece drive shaft, every time i gas the truck from 0 like in a light I hear a tock noise do you think its the same problem and only needs lubrication? thank you

Just did this worked great. THANK YOU for the helpful video

Great video by the way. I have the same issue on my 2013 F150 FX4 and applied the grease but the issue is back 4 months later. Any other alternative? Thanks

My 1994 has done this since I’ve owned it I’ve gotten so used to it it doesn’t even bother me, and yes the u joints have been replaced and the driveshaft was marked before removal

I wouldn't buy anything but a Ford I've had them all they all have their little quirks it sounds like you're a Ford man too and I love your videos keep up the good I have a 2011 too that noise always seems to sounds like it's coming from the rear not by the transfer is that correct ?

I have the same problem with stoping and accelerating, it feels that bump that you are talking about, but do you think i should replace the whole driveshaft or just the u joint i have a 2011 ford f-150 2wd, but i just wonder if i can save some money on buying the whole thing you know, and thanx for your video, it helped me a lot!!!

They recently rebuilt my transmission and now when I take off i feel a thud. Also the reverse lights don't work and sometimes the van doesn't turn on until i put it in neutral and back to park.

Can you explain why my Raptor 6.2 2011 makes a fuss, like it's beating iron when it turns 180 degrees with the 4x4 on?

One more thing..... Is the grease you mentioned only through Ford or is there a grease that I can pick up at a local parts store? What type of grease is it exactly. Thanks again. I will definitely subscribe to your channel. Great info.
