2011 Ford F-150 Stuttering Sound when Turning 

My best friends cousins girlfriend knows this guy who knows this girl who once talked to another mechanic said your doing it wrong. Keep doing you Wes love the videos

Not only do the folks down south not know what it is like to work on the rusty and crusty, they don’t know what it’s like to have cold , salty slush and water dripping down on you when working on the rusty and crusty during the winter! I sure wish I had someone with your skills and talents in my area! Keep up the great work!

I''m a diyer, not a mechanic by trade. That was interesting for me as I've never seen an explanation of how a mechanical LSD works. I appreciate you including that part.

With cold thick oil, running the pump at a slower rpm will actually move more fluid than running it at a high rpm. You could see in the video that the oil coming out of the pump was cloudy, this is due to aeration of the fluid caused by cavitation in the pump. Love every video!

UK. In 1961 at 15 years old I started an Ministry of Defence vehicle apprenticeship that ended on my 21st birthday. I spent the rest of my working life around heavy vehicles. Watching Wes often makes me realise you can teach an old dog new tricks or at least let him learn something. I look under the bonnet of modern cars and wonder what prat thought of that lot. Emissions - in my day if you could see across the road when you started a car it was fine. Thanks Wes, your making an old man very happy.

Of all the "fancy tools" I've seen you use, the 2 I had to run out and buy were the simple ratcheting end box end wrench set, and a ratchet wrench with a pivoting head. Those have been a life saver.

I tested my limited slip diff once. I dug two holes (in sand) under diagonal wheels until the vehicle was just hanging there. Started the engine and engaged 4WD. No way could I drive out of there as expected. I jabbed the brakes hard while the engine was spinning the wheels half a dozen times and it jumped right out of those holes. A mate of mine did the same thing without LSD and his car also leapt out of the holes as well. So even without a LSD braking the spinning wheel briefly allowed torque to be applied to the opposite wheels. I wouldn’t have believed it unless I did it myself. It’s a great trick that just might get you out of a bog. And if you save a couple of girls who are bogged anything could happen :)

Should have left the wheel seals. A little leaking would help mitigate future rust.

I was a marine mechanic for 5 years before retired. We had a little pony impeller pump mounted to a 7 gallon bucket (sold retail ) to do oil/fluid changes. You can get the pump alone sold as a water pump, but all parts of pump are same (oil ready) great for waste oil, diesel transfer (even gas if you have the never) pump, and yes great for water too. Can get the drive motor in 110VAC or 12VDC too. But the best way was a weed killer sprayer pressure pump can (get the stainless ones with brass spray wand, plastic will work too but metal is better ). Just take the wand and bend to a "J" bend or even just add gas line (flexible), and away you go! When I had my garage at your age I had 4 of them, 1-gear oil, 1 trans oil, 1 brake fluid, and one empty for everything else. They saved me a lot of time & mess clean-ups!

I'd like to add, yours is the only channel I watch without fast forwarding, it seems to me everyone else bores me to tears, not your videos, always entertaining, not wanting to miss a frame. keep it up, looking for next video to relax to Sundays here in UK.

If I remember correctly, I think Valvoline has started to put gear oil in plastic "bags" that kinda look like Capri Sun drink pouches. Worked great for when I changed the front and rear diff fluid in my Jeep. Didn't need to get out the hand pump.

"Basically magic" That pretty much sums it up! Thanks for taking the time to film this, seeing the amount of trouble and attempts to complete the job is always an adventure.

wOw, tearing down a diff isn't what it used to be: no stinking, sludgy grease-like substance masquerading as gear oil! Very nice work- no slips, errors or missed steps. Love watching you work (no pun).

One method I've used to get the differential to pop out is roll a rag between the ring gear and pinion I learned that from my father who use to work for a tractor dealer. I've done this on dodge front differentials and it has worked every time.

Always excited to see you posting another video! Can’t wait for the next!

thank you for another great video. I really like how you show the work, not just say what you are going to do and then it is done

Love watching you work Wes! Thanks again!

Would have liked to see what the friction plates looked like after 200k+ miles. I've got 125k on my 8.8 lsd and suspect there's not much friction material left on the linings.

Yes finally! Been waiting for a new video to drop. Keep up the great work. Wish I had a l great tech like you in my area.

Thank you again Wes. I always learn something and really enjoy your presentation. Have a great day.

Thanks for the great description of how a limited slip functions and the difference between a limited slip and a locking diff. Excellent work.

Always interesting and informative...thanks Wes for the the upload.

the longer the video the better, i had withdrawal yesterday and watched a few of your vids from 2 years ago

Wes thanks for sharing all the details and what is and isn’t needed to do the job. You and family stay safe and well 👍

Been watching for years, your humor and work ethic makes some of the best content on YT, your really up there in quality content like LD18, DP, etc.

These are the only videos on youtube I click like before watching. Because they are all awesome!

Great job Wes. Very good explanation of operation and great closeups of the repair. Thanks for sharing.

thanks Wes, you know what they say, work facinates me, I could watch it all day

Hey Wes, I don't know if you will see this, but I really appreciate your videos and they have helped me tremendously in troubleshooting and diagnostic issues. Not only in automotive but also in the way i approach my job in troubleshooting complex issues at my cellular tower sites. Thank you!

Good video, Wes. About the fluid pump, I made a similar tool out of an old small block chevy oil pump I had laying around. Spin it with a 1/2” drill. Pumps a lot faster than your new tool. 👍

YES, thank you Wes for another video. I was going through Watch Wes Work withdrawals. Keep up the good work.

*Stays tuned with great anticipation * An excellent video as per usual. Thank you! 👏

Always impressed to see you pull something like this apart and then reassemble with zero issues. Rear end gears are not tolerant of foolishness!

Wes, Very informative and detailed breakdown/rebuild! I learned a lot! Thank You.

nice job wes. thanks for taking the time to explain the physics behind the functionality of a limited slip rear.

Appreciate the insights on on how the limited slip works. Have heard the term but never knew what went into it.

Hey Wes back in the day I ordered by cars with posi-track - great tutorial on this fix - enjoy your videos they are always very informative !!

Very informative re: lockers vs limited slip. Which I'd known this 20 years ago.

That made me ecstatic that I am too old and infirm to task such a task any more. The way you told it all made sense, and would be extremely useful to someone facing the uphill task for the first time, as you did.

I'm here to watch you work on a differential and I'm going absolutely bananas. Just wanted you to know, Wes. Great video.

I Bought one of those transfer pumps because of him as well! Little slow on gear oil but trans fluid is a breeze. Well worth the month. I’m looking for things to us it on now lol.

Dad would have loved having one of those pump when he changed out the final drive lube on his little dozer. No quart size squirtable bottles back then. Probably spilled twice what he put in those drives. He was oiled from head to toe when he finally got done. He considered making use of an item that was stored in our bathroom cabinet, which would have utilized a coat hanger while used for it's intended purpose ... but I think old school modesty and the fact that the community had a rather active rumor mill at the time kept him from buying one for that use.

Thanks for the explanation of how the limited slip works! I've never had to deal with one but have off and on thought about how they function.

Great video. I have seen that pump on SMA . Can’t wait till your next video. Keep up the great work young man.

Beautiful explanation of how a limited slip diff works. Now I understand. Yes, the gear oil probably would have pumped faster if it had been warm. It was also getting a lot of air mixed into it, which was probably part of the problem. That could be the inlet connection, the shaft seal, or the gasket around the pump halves.

One thing I recently learned about are systems that use wheel sensors and can apply the brake to a single wheel. It can assist a LSD or open differential to transfer power to the non slipping wheel

Always enjoy seeing a diff taken apart. One of those beautiful and elegant solutions to a problem that I just enjoy for its own sake.

Isn't it the truth Wes that a lot of those parts diagrams leave out parts in the pics ,great work by the way 😀

Nope. That’s a “ let someone do it” job. As always Wes. Good job.

I had that same problem on my 2001 Ford Expedition Eddie Bauer. It stopped after I changed the speed sensor on the top of the rear end housing. Now I'm wondering if it also serves as an axle housing vent. Never had the problem again. I still have the vehicle, just turned 250,000. Runs like a top! I bought the truck in 2005 when it had 40,000 miles on it. I change the oil every 3,000 religiously. Thanks Wes. I'm learning a lot from your videos.

Good video Wes and I like the way you explain how the differential works. So many people don’t know.

I appreciate the video titles being the problem to diagnose, not the eventual solution. Gives me a chance to contribute some wild guesses.

Seeing the dripping slush was a reminder to a simpler time. Working on cars that were covered in melting ice and snow, coated with thick mud from the 3 miles of dirt road we lived on. Scraping to find bolt heads, and getting dirt in your eyes (remember those vinyl goggles with the elastic strap? Never worked.) I don't miss that too much. And thanks for the tool review. I appreciate those as well. Still saving to buy that ratcheting pinch bar.

I really enjoyed your explanation of the limited slip functionality. I heard many many ways to simplify the understanding of it's function. And this really did a good job. For those who haven't had one apart in front of them this is a pretty close second. Keep it up Wes!!

Thanks Wes! Its always a pleasure.

Best video I have seen on this. Great job thank you for the content

Hello Wes, one trick i use is to preheat the gear oil in very hot water, then use the ( drill pump i got from peavy mart for 4.99 Canadian about five yrs ago.) Done in less than 7 minutes. Great show two thumbs up

The Factory Ford Service manuals seem to always call out a special tool for every job! I like the creative approach to accomplish the repair without specialty tools. Nice job Wes! 👍😁

Amazing, I have always wondered how a differential worked. Thank you.

Excellent work as usual Wes 👍

Love the fact that you're approximately half my age and already just as bitter (to be truthful I was probably there in my thirties as well) when it comes to whiny people. Love your vids mate. Just keep doing what you're doing. ❤🍻👍

With regards to the pump being slow, move the bottle ABOVE the height of what it is you wish to fill.... Fluid naturally wants to go down, keeping the bottle low only adds to the strain of the motor as you attempt to lift the fluid against gravity. Also, heating the thicker oils in a tub of warm water will make the process even faster. Another excellent video, thank you for all of the quality work you do both in and out of the shop 👍👍👍

Excellent explanation Wes. I learned a lot watching this video as always.

I've rebuilt a few chevy style tears over the years. I was told that they are harder but you don't need extra tools. Love the channel I always learn something, a better way, new tool to make things easier. Thank you

Great description on the operation of the clutch's! BTW, I made a transfer pump out of an old electric fuel pump. It's a bit slow (3 mins per quart) but it does the job.

I hear the heater!! 😂. I did the clutch pack in my foxbody and had to wear a motorcycle helmet when I put the “S” spring back in. The first time I tried to get it in it shot across my garage at mach 2.

Nice going, I like the way you adapt the tooling you need

Rebuilding my 95 8.8 limited slip this summer was on my schedule. I usually look forward to summer but you just changed that for me lol

I did a similar video of the clutch pack replacement in an LS Chrysler diff in a Dodge Ram, and to my surprise it is nearly identical to the Ford version you show here. The only significant difference is the way Chrysler use threaded adjusters to adjust ring gear backlash and axial preload, rather than shims you show here. It's easier to get the diff out but you need to make a special tool to get backlash into spec. Great video, Wes!

Wes you amaze me with the work you do with so much rust and corrosion on the vehicles, I’m convinced that these are your special skills. Keep up the great work! Winter is almost over ✌️

Good morning Wes Love the channel

Nice work Wes always enjoy your videos..

Working on vehicles in a Midwestern winter, getting a salty, sandy, dirty shower while trying to change an oil filter. Yes, the struggle is real! Working on my company's fleet of trucks during the winter in SE Iowa I know the pain Wes!

You scared the hell out of us. I thought we had to wait another week...:)

excellent description of limited and locking differentials wes

There is almost zero possibility that I will ever have to do this job but I watched the video anyway. You and a couple other folks, including Mr O, have managed to actually teach me things about how mechanics work. Both the human ones and the mechanical mechanics.

Another great video, Wes! Wrt the transfer pump, did you have the drill in high? Is it a 'fast' drill? Or more of an impact type? I'm sure Eric O will be along shortly to tell you what your problem is :)

The more I see the newer auto line up the more I like older autos to be honest!

Excellent video, Wes! I especially enjoyed the "Professor Wes" segment concerning how the LSD functions.

Great video bud! You gave us a lot of good information and made it easy to understand. Thanks!

Hey Wes - great videos as always! On the transfer pump - judging by your attire, I'm guessing that that oil is closer to the 140wt than the 70wt. Try putting the bottles in a tub of hot water for a bit before pumping. It should help speed up the process.

SMA TOOL ENVY????. I watch both channels and appreciate the quality hard work and great vids from both. Did i miss the vent installation that Ford Mothership recommended?

Great job as always Wes.

Wes, you have one hell of a mind, to remember how to take stuff apart, then to put it back together, it's so bloody amazing, so don't mind people who are jealous of you're abilities.

That gear oil looked pretty aerated coming from the pump. I wonder if that pump is bad? Nice video like always and thanks for showing the guts on how it works.

On the spider gears to hold the washer use a dab of grease to hold then makes it just a bit easier

Didn't notice till the end but the rear cover didn't even have a fill plug! 😵 Great job with the repairs Wes!

Thanks Wes for sharing and always interesting content 👍

I'm pretty certain that 9 out of 10 times the people who write service instructions for vehicles have never actually worked on a vehicle in their lives.

Hi Wes, Would your new pump toy work better if you heated the gear lube first? Maybe even hot tap water enough to help. Thanks for the great video. Take care Wes

Dude, you know your mechanical skills. I followed what you did on my 2011 Ford F150 lariat and it was a pain to do but, you were spot on with the steps to fix the pionion clutches. Thanks for doing the video

Great insight to a limited slip differential, very interesting Wes. We missed watching the truck acclimatise In your shop, must be an important part you missed. 😆 🤣 😂. Excellent video Wes, thanks for sharing.

Robins are massing in my yard(north of Tampa). Spring is coming.

6:56 Behold, everybody - he has a 10mm socket - long one too - that's not missing! :)

Great channel always a good watch everything you do shows you want it to be done right

Job well done. Lot of interesting info in your videos Wes 👍👍

Update to TSB; under extremely rare conditions, when outside temperature drops below 6F, wheel may fall off. (Replace at technician's discretion)

Another outstanding job Wes. I don't know how much you paid for the Tool Guy Fluid Transfer Pump, from a quick search it's circa $100, however for $30 you could get a 12V Oil Transfer Pump that has it's own built-in motor and just needs 12 volts to run. This is what I use and it works great for oil, fuel, coolant, and so on, and at that price you could have a number of them and use each of them for a specific fluids.

It's amazing how different the vehicles are between areas of the US. Rainman Ray's Repairs in Florida has nice looking 20 year old cars and you and South Main Auto are working in 10 year old piles of rust. Keep up the good work. Love the videos.

Loving the detail, awesome video.
