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
+hasaywha Thanks for the feedback! We'll pass this info along to our production team.
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
That’s what closed captioning is for
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.
In '84 I bought a Supra. The diff was noisy but the dealer said not to worry. 205,000 miles later when I sold it, the diff was still noisy.
toyota reliability at its best
this was an exceptional video. very informative. thanks a lot.
Finally a good video by 1a auto! Two thumbs ups!! lol
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.
My crown vic is having what appears to be a similar problem. Glad I found this video.

Excellent video! Maybe the best I’ve seen on the topic.
I am extremely impressed with the level of his expertise. I wish he was who I took any and all of my repairs. What a rockstar
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 ?
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??
Good video and your mechanic did a great job. Nice to see younger kids in the business.
+Tim Hasselbach Thanks for checking us out!
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
Hi bro thaks the vidio. I have same same problemer. Vito 113 cdi 2.1 2010. Loud soud when i Change the 2 gear. Please help.thanks
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.
+Sonny Burnett Thanks for the feedback!
Yes Finally a video describes the noise I’m having in my jeep ..thanks
Same here!
Same here! Been HOWLING for 5 years. It's gotten significantly worse past 2 months and now other bearings are going out
I hear a noise only when decelerating and a lot of fluid leak from the pinion side what could this be
Superb job to thumbs up for that mechanic in his great great work.
+KEITH KUHN Thank you for your positive feedback! We are happy we could help!
I love you videos that very helpful thanks!
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.
+Jared Mayer Thanks for checking us out!
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.
Andy you need to do more of these. But I'd like to see you do more stuff in 2500s 3500s
This just might be my issue. Would you know how much for the repair?
~GREAT Vid
Very informative video. Thanks!
Great video. What's a job like that cost? Thank you, John
Good video. Thank you.
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!
Great video!!! THXS👍
+Mustang Thanks for checking us out! 1AAuto.com
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.
+Jeeper80 Thanks for the tip!
great. answered my questions on why I have dif noise
How long should I drive it to let the new differential additive oil get in there well?
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?
But how do you adjust the backlash? shimming of the bearings?
Shimming
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!
1A Auto Parts is that would be the cause. Should I go to my dealership or to the one who fixed my car ? 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 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.
Good video
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?
Outstanding
Thanks for checking us out. 1aauto.com +Mr. Roy
Is that backlash play suppose to be the same for most vehicles?
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
Always by good plan with very law cost could rectify problem
+vito atari Thanks for checking us out. 1AAuto.com
Good job on the video very explanatory thank you.
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?
excellent vid. TY
Mines sounds like metal clanking when I accelerate but I can’t tell if it’s the front or back one and if it’s not a axle or not
Can you make a video on the bearing near the wheel? I think I have that problem on my jeep xj
Saul Perez Esparza hey any update on your Jeep? I’ve got a weird choppy humming noise rear end on my patriot
Kingg Casanovaa out of no were it stopped making the noise, I haven’t check since then
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 😓
How do you adjust the backlash ??
Excellent video - well detailed too. Thank you.

Thank You! Answer my question.
My rear end makes noise after eating Mexican food. Sounds like air escaping, just changed out my diff. and now the noise is fixed. Thanks man
Don't leave the plug in there too long. It may cause excessive pressure buildup, thus causing your rear end to explode.
I laughed way too hard at this comment 🤣😂🤣😂
Hi mine is rumbling quite a bit, is it ok to drive for a while till I can fit it in at the garage in about a weeks time? As I need it for work
Check the oil level
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 bought a front drive shaft for my 2006 Yukon from you guys and the boot already blew is that covered under a warranty
+Jeffrey Conway Thanks for watching! If you have any issues with a part you ordered from us please be sure to contact our customer service department right away! Our contact info can be found here; www.1aauto.com/about/contact
Did you replace the pinion, as well as the ring gear? and did you use the same shim on the pinon?
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?
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
I get some noise from my Honda crv rd1, but it's differential looks different from the one you are handling
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?
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
+CZ TS !!! We recommend always following your manual for the oil that your truck uses and not altering from that. Thanks for watching.
Thank you
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
The Lucas was a mask for them not setting up the gears properly. Needs to be shimed to the right.
Danny
So you want to move ring gear closer to the pinion?
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.
+@michaelsmithdjsmitty4538 We wouldn't be able to diagnose an issue like that here, you may want to have a local mechanic take a look at it. Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
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.
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?
when should you change the differential fluid
90k+
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.
do you have a video on how to remove everything
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 ?
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.
So would just replacing diff fluid get rid of the clunking noise?
I need a GMC Yukon rear diff asap like now you said click the link for parts but I don’t see any contact information
What was the sound it was making?? A thump?? And did the sound appear when coming to a complete stop like a lunge forward type of feeling??
In the beginning you can hear it but only if you're familiar with the sound. It was howling/low pitched whine.
I just put in a new ring and pinion. New bearings as well. Backlash is good but I m getting a howling noise on acceleration. Any thoughts.
Rowdy Rubio my 02 trail blzr doing same. Pinion running to shallow, excessive end play on right axle.
Rowdy Rubio did you ever figure out what was going on with the rear diff
What is a rough estimate (price) on what you just worked on
$1000
That sounds about right a shop just gave me an estimate on a k2500 for $1,200, this truck has less than 100,000 miles on it and hardly ever towed
They charging me 1400 for the whole part and new filter,gasket and oil for transmission is that bad ?
How much does a rebuild job cost on average? Am trying to decide whether to fix or scrap my 91 G-20 van.
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?
What did it end up being?
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 ?
my car have problem like this,when i go uphill and rev is about 1.5 voice like this comes from back part of a car..can someone help?
Any idea much and where can I shop 2018 Nissan Pathfinder Platinum Differential... ?
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.
SUPER VIDEO. A RARE VIDEO ANDY IS A SUPER TEACHER.
How much does it cost for a job on a Nissan frontier v6 XE cost? Any help would be great
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$
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
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?
i have like this problem when i turning left or right some noise happening is that also differential? w205 RWD
Thanks. 2 thumbs up
What would be causing a shutter when (slowly) accelerateing from a stop? It's worst when making a right hand turn.
Limited Slip differential?
Gong threw the same when from a stop to 40mph found out my differanl is bad
How about a brand new carrier assembly with nearly zero backlash and failed bearings?
Jack Tradesman nearly zero? There’s a spec, there’s got to be some backlash. Find the spec, if it’s too far out you’ll have Noise.
I just put yukon gears in my 4wd 2018 1500 sierra denali..there is a different in noise when accelerating and decelerating..is that normal?

I have whining noise form rear left driver side at 45 to 70mph could it be the wheel bearing?!
I heard you replaced the ring gear.
Did the pinion gear require changing with it?
You replace them as a pair
You should always replace both
He replaced them as a set. The ring & pinion are a matched set and must never be mix-n-matched with others.
What if the clunking happens on a cold start ? Almost like a shaking that goes to the rear differential
Almost all 10 speed Ford do it. Even mustangs...good luck.
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 had a scraping sound in my 1999 Cherokee Limited and felt a clunk, when I pulled over to find out where the clunk came from I couldn’t find the source and when I put it in drive it made a loud grinding sound and wouldn’t move even any other gear I have it in except for park. Would I have a bad differential?

I don’t have it anymore, I sold it back in November 2014 and currently have a Ram 1500 4x4.
How much does the labor cost for that?
800
Thank you
He is troubleshooting like a pro, just saying, it does not get done better than this.
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 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 .
