Please ditch the music. There were times when his voice volume dropped and then muddled with the low music. It really isn't necessary to have music. Other than that, I thank you for the information that you provided
You don't have to ditch the music entirely, just put a compressor on his vocal track to equalize the volume of his voice so it always clearly heard above the music
Absolutely ditch all the music, if your content has value, as yours does, you don't need any bullshit noise to distract from your instruction, and the sounds of the work itself.
I have a humming sound on my rear driver side. I thought it was the wheel bearing, replaced it, but that wasn't the problem. What you are describing might be the issue. Another issue is finding a mechanic that knows his stuff.

That video actually is the first one of its type that I have seen and that actually explains the problem of clunking or diff noise and gives a detailed explanation of the solution... I hope these things would apply also to the old audi a4 quattro rear differentials. Many thanks
Doesn't tell you how to adjust the backlash or does the new part fixed the backlash? How does the backlash get messed up in the first place ?Helppppp... great video though you really explain yourself well sir.
Dial indicator - There’s a way better dial indicator than the one you were using to check the backlash. You get a lot of cosine error using the method you were using. Like .008 actual measurement shows up like .012 on the dial. Basically it is easy to have things too tight. You should be set up parallel to centreline, square to the tooth centreline for accurate measurement. Pattern - If your pattern is good on the drive side your backlash will be right and the coast side will be exactly where it is machined to be. You can move the contact point around but you can’t change the drive-coast relationship. It’s how they are ground.
If i have a low humming sound when you give it gas and goes away when you coast is this a big problem or should I just drive it or need to be fixed it has 240000 on her. Thanks Sir.
Hi - I think this is a great video and I easily understood what needs to be done to diagnose this issue. What would you say a friend should be charging you to do this work for you as a side job? 2013 Jeep Wrangler or a friend of a relative? Even is they are a high end mechanic
Put new set of gears in my GM 10 bolt notice during the break in it makes a slightly sound when slightly on the gas , Did the backlash to specs any idea ,And BTW what brand gears did you use ?
If the noise is only there only when accelerating, would you say its the pinion and ring position? Or also possibly the bearings? Or would the bearing be constant?
my 1997 expedition is making a grinding noise near the right rear. but usually only when im turning. when i push on the brakes it stops. i was told it has something to do with the emergency brake. could this be true?
My 02' Blazer ZR2 w/ a G80 Locker in the rearend was making a whining sound at 25mph & faster. Found out it's my Pinion Bearing going out, even though everything is tight & no leaking. No clunking, etc. Just a whine. I'll turn the radio up a little louder lol

I have an 02 ram 1500 with 3.92 gears... just completely replaced the rear end as the old one got ran dry and i drove the truck till it imploded.. it seized and ended up taking out my driveshaft, gas tank, overdrive housing on my 46re trans, exhaust, etc. Bought all the parts and rebuilt the truck myself for about 1300$ but would have easily cost 5000$ in parts/labour at a shop. Long story short if you hear alot of noise coming from your rear end stop driving you'll save alot of money in the long run lol
His description of when this pickup makes it's "Noises" & how it sounds as well is nearly match to what I've got with my 2002 Toyota Tundra. Unfortunately, Tundra's have no removeable rear cover to check anything. Since the rear differential & axels are all within a housings & can only be serviced by unbolting the axel coverings (I think, it's been awhile since I really looked at all of it) it's a monumental undertaking to do any work on any part of what's back there. I believe the mechanic I had "Look & Listen" to it came to the conclusion that it's axel bearing was the problem, but learned it was "PROPIETARY" to my pickup from some information (rather obscure information) he found somewhere. If anyone could direct me to an "OBSCURE SOURCE OF INFORMATION" regarding an odd size of the rollers/balls used in the rear end axel bearing/s in a 2002 Toyota Tundra, it would be greatly appreciated.
I'm having my rear differential repaired tomorrow. I drive a 2017 Infiniti QX30. It had 10,800 miles on it when I bought it in July of 2020 and now has only 25,500 miles. Despite the low mileage, I started getting a whine about a month ago, had it looked at last week, and was told the rear differential is "shot". I didn't buy that for a second, so I'm bringing to AAMCO Transmission, who thinks it will probably need minor repairs considering the mild symptoms and low mileage. I guess I'm the culprit for never having changed the differential fluid, but I had no idea it was a maintenance item. I'm 65 years old, have been driving various makes and models of cars for 50 years, and never changed the differential fluid and never had a problem. I wonder how much time it took for this guy to fix this one.
Got my rear diff done by a local highly recommended shop with lower gears and a trutrac installed, makes a howl on decel at 40-45 brought it back says it’s no big deal and such they put some Lucas in and was quiet for a month or two and it’s back been like that for two years hasn’t gotten worse but sure is annoying
I have a 2007 Chevy Avalanche, and the noise I hear coming from the rear of the truck sounded like the Sway Bar Links were dry, so I went and purchased a hand held Grease Gun from Harbor Freight and added grease, but that did not eliminate the noise. I then raised the rear of the vehicle and shook the tire, and discovered there was "in and out" movement of more than 10 thousands of a inch. Is this a Bearing problem, or something more??
Can a carrier bearing cause a shuttering, almost a crunchy vibration at slow speeds after a few mins of highway speed? It doesn't do it unless i run 60-70mph for 10+ mins. I also have a humming sound that seems like a wheel or carrier bearing. I'm having a hard time getting the prob diagnosed. It's an 07 AWD Saturn Vue.
Did you ever figure out this problem? I have something similar in a suburban, at highways speed, but it takes like 15 minutes of driving before it happens.
I HAVE A 2012 RAM 1500 4X4 AND AS I AM DRIVING DOWN THE ROAD AND IT HOWLS OR ROARS AS I SPEED UP .if i turn to the right the noise quiets down but it doesnt when i turn left. To me it sounds like its in front end ? Would that actually still be the rear diff. The truck has 169000 miles on it .

You'll get a better pattern if you push the ring gear against the pinion. Easier to do than turning the pinion and produces a nice pattern since you're pushing against the pinons gear preload.
I'm having issues with my 2013 BMW M5. We changed out both axles but now I'm getting noise in the back when I'm accelerating and getting a drive train malfunction. Any ideas ?
I got a 4x4, does it on deceleration, but sounds like in front. Would this be same issues but just in the front differential? How would you check front one, sme way as the things you're doing for this rear diff? Im just trying to figure out few things before i start repairing whatever is making my noise on deceleration. Thanks!
Hi, Question: I am traveling and near Saint Augustine, Florida, do you know who rebuilds re-ends in this area, or how to find some one honest and qualified? My front seal just blew out. Need to decide if I fix or crap the van.
Hi I’m looking at a 2007 Yukon Denali he says there’s a brand new engine in a newer transmission that was installed. He said the rear end is jumpy and thinks the rear differential is going bad. Not exactly sure what that means?

Hello guys I just had a over a year old 2019 small compact suv. And it’s been. Rear ended last year. I bought it new last January and I been rear ended. March 2019. They fixed it and now the noise come. At the rear Thank you
+Christian Basa Thanks for checking us out! We would suggest taking the vehicle back to where it was originally fixed. Please let us know if you have any further questions, thank you!
I have rear end clicking, during turns when engaged in 4x4 :/ mechanic cant figure it out, when its in 2x2 no issues when turning or driving, but when i engage 4x4 it has clicking sounds, any idea? There,were some damage to the side of the tire before, but axle is not bent and passed alignment no issues?.... any clues? Thanku in advance!
My 2009 F150 rear differential only makes noise on real light acceleration under load meaning if I have it on the list I want to hear the noise at all not sure what it could be
I have a 09 GMC Sierra 2500 gas and I’m at 150k miles. Doing the exact same thing as this ford I can feather the throttle and it’ll make a winding howling noise. Basically only under load but once I let off it goes away. But after watching this video it’s basically everything in the rear end is done for I guess. How bad is it to keep driving it as it is?
I bought a 97 F150 in late 96. It was perfect until a recall and the dealer said they knocked the weight off the driveshaft and had to replace it. After that I had a roaring noise from the rear and took it back. They said it was the Firestone tires and I would have to take it to them. About that time I got a company car and almost never drove my truck. I just lived with the noise for years when I did. Finally had the tires replaced and the noise remained. 97,000 miles later it’s still there. Truck runs great but I can’t find anyone who can tell me what’s causing the noise.
I have a 96 k2500 and mine makes noise when you let up on it not when you're accelerating bearings? Carrier bearing? The truck was dad's and is a pampered garage Queen with 98,000 miles on it
I'm struggling here. Need your advice. My wife has a Kia sorento, 2WD, 180,000 miles. Never, ever any problem. No roar, whine, or anything. Problem. We had both my grown grandsons riding in rear seat, hit a bump, sounded like the rear bumpstops bottomed out. All was well, still no obvious problem. The next day, as we were taking my grandsons home, we drove 68 miles, 2 lane and a few miles interstate. When I got to our exit, we completed the turn, no problem, but as I pulled away from the traffic light, one helluva vibration, throughout the car. Sounded like we were traveling on the "rumble strip" on the side of the highway. By this time, I'm creeping, thinking we had a flat tire. Car would quiten down, then start shuttering again. We were just creepin. I thought I may have a bad rotor, replaced front rotors, pads on all four wheels, checked for bad spots on tires, which are new. I checked the driveshaft as well as I could, no "slop in the driveshaft, no "pop" shifting from park to drive or reverse. I even replaced the font wheel speed sensor/ ABS sensors, even though I had no code. Scanned it, no codes were stored at all. Pulled the ABS fuse, got a code, replace it, code cleared. Had to have it hauled home on a rollback wrecker. it is undriveable. My next, and last guess would be something in the rear diff. Nothing I have done has made any change. I respect your opinion, of course, I've never set one up before, so I'll have to take it to the dealer. What do you think, my friend?
On a 4x4, if my noise does it in 4hi, would that mean it's NOT the front diff? Could i rule out the front one? Im having hard time telling if sound it's making(on deceleration only), is in the front or back. Any help is appreciated! Thx
Hello I’m hearing a wine from my 2017 scatpack challenger when I step on the gas not sure what the problem could be when I let go of the gas pedal it goes away ?
I have a BMW 530 I have a rear differential humming sound not like this exactly, it's smooth but annoying Is it really dangerous ?? Can I drive for a long trip ? Is it just a sound or should I fix it soon ?? It will cost me 3000$
Saul Perez Esparza oh lucky you hopefully doesn’t come back I’m looking at a $1500 fix and could possibly be more depending on if other parts are damaged 😓
My 2012 mustang V6 is making noise in the rear end and it’s also leaking oil. The noise it makes is like it’s grinding against something and like a roaring noise as well. How do I fix this and how much will it cost me to fix this? I was told to not drive my car until I fix it. Where should I go and what should I do? Someone please help and give me some ideas. Can I do this job myself?
My rear was making similar noise and an oil change solved the problem. I was on a road trip and didn't own a dial indicator thus didn't measure backlash.
Thank you for your video. Would you be able to guide me with this issue I'm having. I have a 05 chevy tahoe, 3.42 gears. GU6,G80. lately when I turn in either direction at a slow speeds, my rear wheels start to lock up and drag as if I was braking but I'm not. I am also starting to hear a growl when coming to slow stop. Any idea on what can be causing this issue and how to remedy. It's my daily driver and need it back on the road. I am also running 37" tires. Your input or advice will be greatly appreciated. Thank you
So basically what this is telling me is.. if I don't want to spend several hundred dollars for parts, and several hundred dollars in tools, less a whole day of work and a machinist degree in mechanics, then it is just easier to get a $250 junkyard rear end and be done with it. Sometimes you got to know when to hold them, and know when to fold them.
Exactly, I have the same situation with my 2010 Silverado that last owner put a Yukon dirá grip and rear gears. It makes the noise when feathering the gas and goes away when I let off. It’s annoying, I really considering just going to the junk yard and swapping out the entire rear axle assembly my self and call it a day. It would be a hell of a lot cheaper fix .
Excellent information but PLEASE learn to control the audio levels when editing your videos. The voice level was so low I had to crank my volume just to hear him speaking and then at 5:53 your logo transition comes in and was loud enough to wake the neighbors! How did this get past your editor? Wow! I'm not hatin - I swear. I loved the video. Your videos are always very informative and extremely helpful. I'm just trying to help. Unless it was just me.... Anybody else lose an eardrum at 5:53?
Very informative video! You definitely have thorough knowledge of your craft. I was trying to find out the possible cause of much body noise in the rear of my 2002 nissan pathfinder. Can you help me with a solution to end the annoying noise?
Are all mechanics proficient with differentials? Or, are they like transmission specialists? What kind of mechanic do I need to get my differential fixed? I think it needs to be looked at by someone who knows what they’re looking at as there is a clunk when I start from a dead stop. That is the only time it occurs. It doesn’t happen when coming to a stop. It’s a 2004 F150
My 2006 Dodge Ram 1500 is making this noise when I start accelerate slowly and when I get to 50 mph it gets faster. I either have a bad differential problem or it would be the back bearings. I got the two front wheel bearings done while back.
Your truck has an AAM 9.25 diff. The small pinion bearing starts to make noise around 90-120k (miles). often a rebearing job is all you need. also the limited-slip diff. should be inspected for clutch packs and tabs coming apart. If need be, replace OEM limited-slip with Eaton/Detroit True-Trac.
i have a 2018 Jeep Compass 4x4 with 2 speed diff (locking 4wd). Around 35-40 MPH i hear a low hum through the vehicle (can't pinpoint front or back of car.), constant no matter how much or little i accelerate. However, If i turn the Traction control off, it goes away. Any ideas?

I have a F150 2016 only 182.000km and i have that problem.. is look like a big problem with the Ford F150 a never have that problem with my Ford Ranger 4x4 XLT 2009 and i have 355.000km on its. Can you drive for long time with a hauling noise . like that's ???? 🤔🤔🤔 before readjusting the back lashes or change pinion abd ring Gear.....
I'm confused about the differential. I'm looking everywhere for a maintenance schedule of differential fluid for my Honda Accord but I can't find anything. Where is the differential located in my car and should I be changing this fluid on regular intervals? Thanks!
I’ve just picked up a brand new MY20 Tiguan Allspace (Tiguan in US) and on the day of pickup I noticed a noise that sounded like an old air conditioner’s refrigerating system kicking in when accelerating gradually through D1-D3 initially and now all up to D7 as long as it’s at around 2000rpm so engine noise can’t mask the noise. The noise is not intrusive and my passengers don’t notice it at all. It’s my first 4 Motion VW with Haldex system and on courtesy call salesman at VW dealership tells me it’s probably “the humming noise from 4 Motion rear diff”. I haven’t had it checked by the service department yet but I’ve only had the car for a few days and it has 330km on it at the moment. Is this type of noise that you’d get from the bad ring and pinion or carrier bearings?
im having the same noise when accelerating on my 2012 nissan frontier. Im being told there are no replacement parts for my differential (M226) and I need a complete new rear end. The oil was like chocolate milk. I dont go in water or off roading. its a mystery to me.
Is it ok to use a lighter rear differential full synthetic oil 70w-90 from oem 70w-140 on my 2015 Ford F-150. I don’t tow and just use my truck for commute and minor diy project at home. Thanks
I dont have a whining rear end however whenever i turn my rear end pops almost like i have dif lock on. It also only happens when i have a load on my trailer 5k pounds + Anyone have any idea what might cause this i drained my fluid cleaned it out put in the stupid expinsive ford rear end fluid and friction oil still have the problem
