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.
View 10 RepliesThe MK6 GoRf seems to have a problem with the Rear Harmonic Balancer on the Driveshaft to Haladex Coupler. I will have a look under the car this weekend just to check it out. By the way, I have no driveline vibration under acceleration. Wonder if the problem is with more power/torque on the turbo engines. But we have plenty of boosted VR6 engines, and I wonder if there are problems with the part.

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.
View 14 RepliesIt 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.
View 12 RepliesIn my 6 day old Golf TSI, I'm noticing the rearview camera is quite noisy when it deploys and retracts. I don't recall how it sounded during test drives, but I'm surprised I can hear it at all, let alone as loudly as it seems.
Likely normal, but thought I'd post this up to see what others are experiencing. Might drop by the dealership and check another one out for comparison.
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.
Any tips for keep rear tire wear to a minimum? Mine are starting to cup along the inner edge and are very noisy at 20, and 40 mph. 20mph is worse even in the front end.
View 7 RepliesWell 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 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 ?
We have 37k+ miles on our 2009 SEL. The rear brakes have become noisy. No warning lights.
View 5 RepliesMy 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?
View 1 RepliesMy 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?
View 2 RepliesI just got word that the rear differential is bad. Santa Fe? I only have 9000 miles on my vehicle.
View 24 Replies2000 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.
View 14 RepliesMy 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?
View 4 RepliesAny likely culprits? 2002 F150 (with Triton V8 if that makes a difference).
View 4 RepliesI have a bothersome bottoming out type of noise coming from near my empty trunk or underneath the trunk area. I have the 17" stock rims with stock mich. tires. I had VW check for the rubber rear shock absorber plate which I do have. I Have the rear tire secured as well as the battery. I have insulated the hard foam tool storage kit so it will not bounce going over irregular surfaces. Yet I still get this sound like a loose bar hitting against the underneath on less than perfect roads.
