Golf IV R32 :: Rear Differential Whine?
Feb 11, 2010
So I have the dreaded rear diff whine, which started about a month (1000 miles) ago. I've read a bunch of the past posts, but still can't find a solution other than a) live with it, or b) spend $3500 for a whole new diff. (95k miles - no warranty) It seems the general consensus is that the problem stems from a loosened pinion nut. Is there no way to just tighten the nut? Or if I do will the whine continue because the gears are now worn? BTW I just had all the diff and tranny fluids changed. Made no difference.

Well i picked up a 96 4x4 with the 4.0 a few weeks ago and been fixing stuff weekly that i find wrong. One thing i noticed was the rear diff was leaky but couldn't get the fill plug out so left if for now. Last night my wife was on interstate and it just started making a loud noise so she pulls over calls me. I get there and drive it and it makes a woowoowoo noise and it got louder as speed increased. She was 3 miles from the exit so i drove it about 15-20 to get it off interstate than another 2 miles to her sisters. We let it sit for a few hours and found a flatbed to haul it home, and when we finally got home i drove it off the flat bed and now it was making a loud clunky noise. Parked it in drive till today. Cracked open the rear and no fluid came out.
Inspecting all the gears looked good no metal in bottom so i went and got a new rear cover and 3 qt. of fluid. Put it back together and the woowoowoo was still there but seemed to slowly go away as i drove it around the block. So what else could be going on here or do i need to drive it and warm up the fluid so it circulates? I also noticed a sheeee sound like metal on metal when braking but i changed all 4 rotors and both pads last week but i noticed the brakes in the rear that look like drum brakes was bare but i assume that is only for the ebrake so didn't bother changing them yet. Could those be hitting the inside of the rotor and making the metal to metal noise?

I got a new to me truck. It's a 2004 F150 Lariat 4x4 with the 5.4L. It's got a whine that I believe is coming from the rear differential. I'm going to change the fluid. My axle code is 26 which I believe is 3.73 non-limited slip. My owners manual says to use 75w-90 but I've seen a lot of posts on here that say to use 75w-140. Which is right or better? Also, is my rear differential the 9.75"?

i have a 96 ranger 2wd with a 2.3l engine and a 5 spd manual. everything works except the rear diff whines a little under load. putting new bearings in doesn't look to difficult that's what i will plan on doing but first i need to take the cover off and need to know what fluid to put in?

Any troubleshooting tips on determining where the noise is coming from at the rear of the car? There is a pretty audible hum at 55 mph coming from the rear of the car and I am not sure if its the balancer or the diff. I'm reading horror stories of improperly serviced rear diffs causing the diff to fail and starting to freak out.

It was brought to my attention that staggered wheels Can blow out the rear dif? Is this common? I currently have 18x8 and 18x9 rear summer wheels and I haven't seen any issues occur yet.

Have some 'whine' coming from the rear differential under deceleration. In my case it just started occurring last night and seems to be audible over 55MPH and while in 5th or 6th gear after I let up off the throttle as to engine brake.
It seems like the answer or solution pertains to the input shaft pinion retention nut eventually backing off, as well as oil starvation to the unit, but has this actually been confirmed? My rear diff was replaced over 4 years ago under warranty after it failed and enduring 2 wheel drive for a bit.

My rear diff had recently started to whine on decel, what I am looking to find out is, would replacing the stock rear diff itself with a peloquin unit be enough of a fix, or should the whole rear housing be replaced as well? I don't want to buy a peloquin rear diff and install it and still have issues because of the pinion shaft being the culprit or something else.

So as the title states I'm getting a rear whine sounds more like a dump truck slowing down, anytime I go over 45 mph. I have an appointment tomorrow morning with VW to get it diagnosed and hopefully fixed.
I've checked and properly inflated my tires and there is still decent tread left. As far as I've seen it could be the rear diff or harmonic balancer.
I recently got my car tuned (apr stg I) and I'm lowered on neuspeed race springs with matched bilsteins. I doubt either of those would have any impact on my issue though.

I currently have the rear axle shafts off the truck. I took off, cleaned then put on the rear diff cover.
I live in an area that does nothing but form rust anywhere and everywhere in very little time.
I don't want rust forming in the rear diff gears - can I fill the rear diff up ? Or will it leak out of the rear shaft holes ? Can I fill it up halfway then ?

My 2007 3.6L 4Motion wagon was in for the 40k service. Everything was fine with the service, but they noticed that there was a small leak in the rear differential.
It's covered under warranty, but the troubling thing is that they can't figure out how to stop the leak. They are calling VW tech.

Today, whilst changing to my winter tires, I noticed that with just the right rear wheel in the air, it was possible to freely spin it (all 3 other wheels firmly on the ground). Gear was in Park, engine cut
As I understand, the rear axle has an open diff, so the center diff has to spin too. Is this possible for a (Torsen) center diff?
I experience quite annoying speed related vibrations, so was wondering whether this might be an issue.

Some of you may have seen my recent post about raising the X. Its about 5" higher in the rear. Prior to raising the X, I had a vibration at around 65 to 70 mph. It felt like a tire was out of balance. Go a steady slower speed or a steady faster speed and it would go away.
Since raising the X, the vibration is gone, which I thought was cool. But now I have a "grind" type noise coming from the rear. I have to do all the testing on the freeway. There are no issues, no noises at regular street speeds.
On the freeway, when accelerating fairly hard up a hill from say 65 to 80, I can hear sort of a rumbly, grindy noise from the rear. Its not really loud but I can hear and feel it throughout the cab. If I coast at around 70-75 mph (just keep the speed the same) on flat ground, I can hear it come and go when the X is truly coasting for a few seconds. If I get up to say 85 and let off the gas, I can hear it as I decelerate until I get down to around 65.
This all only happens between say 75 and 90. I get no noise below 65-ish.
I had the drive shaft out over the weekend. The u-joints had no play and were free moving. I did feel the smallest play in the slip yoke, so I gave it a good greasing. That didn't change anything.
I'm guessing the problem is in the differential somewhere. I have not pulled the cover off yet to check the fluid.

Is there a gasket to replace?

My wife has tribeca B9 (2006) and the rear diff light comes on when she is driving and goes off when she comes to a stop. It does not flicker and the elec connector looks OK, and the oil looks good and is full. Can this be caused by uneven tire wear or the rear tires being out of alignment?

I just got word that the rear differential is bad. Santa Fe? I only have 9000 miles on my vehicle.

2000 GMC Sierra, just over 200k, 4.8L, 4WD. Son was driving and the rear differential seemed to sieze up. Internal casing was destroyed, so got a replacement. Matched the size using the code inside the glove box (something similar to GT4 in both vehicles - it matched exactly). Attached video shows the sound that is coming from the rear of the truck. This noise happens on deceleration. Can drive at least 20MPH and let off the gas. Truck begins shaking at 45MPH. There is no feeling of loss of power or anything negative besides the sound on deceleration.
Important note, this sound was present before we changed the differential guts, and is absent when in 4WD. We only hear the sound when the truck is in 2WD.

Last week I broke the pinion and spider gears in in rear end. Well Im getting a used rear end rather than rebuidling mine. What is the gear ratio on the 97 F150 xlt 4.6l 4x4. I figured they would all be the same but my tag is missing on my diff and I was told by an auto parts store that there were a couple different ones.

My rear-end differential came apart and is not repairable. I have a 1997 F150, 2WD, 4.6L engine, 5 lug wheels. Which years have the same rear ends so I can scour the junk yards for a replacement?

Any likely culprits? 2002 F150 (with Triton V8 if that makes a difference).

My 2004 Ford F150 only has 20,000 miles on it but makes a shudder from stop turning left or right. I asked the dealership about it and was told that it was likely the clutch pack in the rear differential sticking. I was told I could try changing out the fluid while also adding a few ounces of some special lubricant. But, they said it wasn't a guaranteed fix. Apparently, they have tried this fluid change and drive the vehicle in figure 8's trying to get the lubricant between the plates. They also said that this was a known problem to Ford. Lastly, I was told it wouldn't hurt anything to keep driving it. I checked some other online forums for Ford F150 owners and this does seem to be a recurring problem. I'm thinking about having the clutch pack replaced but obviously hate to spend the money if I don't have to.
