Transmissions :: 1995 - Chevy Rear End Differential Grinding Noise
Feb 10, 2016
I bought this van (1995 chevy van 20) last year and the rear end made some sounds but not as bad as its now.
So, after buying it I decided to open up the rear end and inspect for any damage to suggest it needs repairs. No signs of metal chips, nicks, or any wear on the bearings and gears. After a while of driving it I decided to remove the carriage and pinion from the rear end to give it a close inspection. After doing this and finding no clear sign of war or damage, i decided to replace the carriage barrings to see if that made a difference. After placing the new bearings back on the carriage, pinion back into the rear differential, and trying to do it all by myself, i lost the marks i had placed on the carriage bolts and clamps since I had little time to get it back together.
After that I had no other choice but to place the clamps bolts where i could estimate they belong. I was done, then drove it and some of the noise went away but a grinding sound on decelerating emerged. Well, now that sound is gotten worst and its more like a grinding sound. I can assume that not placing back the bolts and carriage clamps back changed the position of the carriage relative to where it was, but am not 100% sure. how can I correct the positioning of the carriage? if that is not the issue what test can i perform to find the culprit?

I bought a 1995 k2500 sheyenne. There is a rather loud high pitch grinding/ squeaking noise emitting from what I would say the rear right of the truck. I have completely replaced the brake shoes and new pins and springs. No luck. What I can say is:
1. It hardly gets any louder as I speed up.
2. Still screams when in neutral, as long as the truck is rolling.
3. Rear differential has plenty of fresh fluid when I bought it.
4. If i hit a good size bump, it will run quiet for about 15 seconds.

When I make sharp turns forward left or right and when I back up and turn left or right my car feels wobbly/grinding. My mechanic says he thinks it "may" be the rear differential needing servicing. I have 135,000 miles. Does that sound right? There is no noise associated with this sensation.

I have a '96 jeep grand charokee Laredo with what I've been told is a bad differential. The bearings and gears are all shot, but can't afford to get a new one. I have taken off the front driveshaft to try and make it drivable again, but it is still making the grinding noise it was before. As well as catching real bad. Just wondering if I need to bother with it, or even attempt anything further.

I have a 2002 f150 5.4 with 3.55 limited slip... For months now every time I hit a bump with the front right side there is a loud bang (sounds like a wore out bushing), and if I am driving slow at an idle you can here a thump every time the wheel goes around. And when I turn all the way it sounds more like a grinding sound.... The noise is getting very bad, what it is. I am very mechanically inclined but cannot figure it out.
Everything in the front end seem tight. When I lay under it if I get someone to spin te wheel the thump sound sounds like its in the front dif, kinda echoes through the front drive shaft but u joints seem good. I really think it's in the dif, and I'm hoping the banging noise I hear when I hit bumps is the same problem as the noise when the wheels go around....

For starters I have a 1999 F-250 5.4l changed all 4 ball joints about 15,000 miles ago. I have been hearing a grinding noise coming from the front end for the last month only when I turn left and at slow speeds. I was servicing the TC so I threw it in 4 wheel to check it and it wouldn't engage until I started moving. When it did engage it was a bad grinding/ clunking sound coming from maybe the differential.

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 have a 2007 Chevy Malibu with around 190000 miles on it. Recently, first thing in the morning then I start driving, that car will not shift into 2nd gear for a bit. The engine will rev up the 2000 RPM and stay there. After a while it will finally shift. The fact that the engine stays revved that high for that long makes me nervous.

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.

My car just started making a grinding noise when accelerating. It does not make it while maintaining a constant speed or revving the engine in neutral. I never had this problem before and I am at a loss to explain it. Car is 1995 Camry for what that is worth.

I brought my 4runner in to fix a rear axle seal and to see if they could isolate a clunking noise I've been having. They said the clunking was coming from the rear differential (I believe him as that's what I heard, while driving or even just putting it into gear). They have yet to call me back, but any guesses here as to whether it is a bearing (my guess, as it is most pronounced on a bumpy road) or a cracked gear or something else. I've been driving with a clunk for about a week, but have various clunk problems for the last 80k miles ....

I have a 1995 850. About a year ago, I suddenly had a loud grinding noise coming from my brakes. It only happened in hot weather and when the brakes seemed to be hot. Also, it only happened when I was coming to a final stop, like the last 10-20 feet. I took my car to my "trusted" mechanic. They diagnosed it as being my front pads and rotors, so they replaced them (they also felt the front vibrating.) NOW the brakes seemed okay after I got it back the second time (no loud grinding noise.)
When I got the car back, the weather was starting to cool since it was nearing winter. My winter weather is like 70's during the day, and during this time, there was no grinding. It's now starting to get hot again, and sure enough, that grinding noise is back, but not as bad as the first time a year ago. Again, it is only when the brakes heat up and I come to a final stop (the last 10-20 feet.) If I break lightly, it won't make that noise, and it takes me driving for about 15 minutes for the grinding noise to start (it sounds like metal on metal and loud.) Also, I don't feel the vibration like I did a year ago. I only drive the streets, and have not been on the freeway since I got the new brakes.

At 120K mi, had ALL the service work done. Changing the trans fluid as well as the 4WD differential was due. A noise in the rear diff began. So the mech said a Honda bulletin stated that this happens sometimes when changing the fluid. Ok. Changed it again. ANYWAY, the noise is still slightly there when going from a stopped position .... steering wheel all the way to one side or the other ... and giving the gas. IS THE REAR DIFF BEING DAMAGED?

I have a 1999 GMC Sierra. The rear differential cover was leaking on me for past couple of months, but I was putting it off. FInally this weekend my truck starting making an airplane sound that seemed to be coming from the rear. The sound happened on acceleration only, and increased in amplitude and frequency as the speed increased and as I pressed the gas more. If I let go of the gas, or let it cruise, then the sound would sputter once or twice, and go away. It would resume if I pressed on the gas again.
Since the rear differential cover was leaking, I thought I burned out the gears. When I changed the cover, the gears appeared to be fine. The lubricant was super low, and did smell burned out though. I refilled the fluid and put a new cover on. This did not solve my noise problem though.
Is it still the rear differential that is making the noise? Is it something else? How hard is it, and how involved is it to replace the rear differential? Can I replace its components, and which ones?

Alright so about a few weeks ago I started hearing what sounded like it was time for new brake pads. But the other day I turned the corner and my neighbor came up to me and said he heard my truck making a metal on metal type noise. So I said okay fml, took it to a local mechanic.
Called me today and said the brakes are fine but it's rear differential, he said they put the truck on the lift and used the stethoscope and heard a metal noise inside the rear differential and said that the fluid in there was very metallic.
I bought this truck about 7 months ago from the dealership. It has a total 90,000 miles on it. What does it look like this could cost me worst comes to worst?

I just came back from a long trip and during the 400 miles drive I started to hear noise coming from my differential - kind of like a constant high gear loud noise. I will hear this noise when I start to accelerate and it will only gets louder and louder as I go faster and faster. I had a pinion seal leaked fixed last week and I checked the fluid and it is full.

I have gear noise in my 2007 Liberty 4 X 4. It sounds like it is coming from the rear axle and is more pronounced under acceleration or decelleration.

My 1997 4.0 Rear Wheel Drive is making a clicking noise when it is put into gear or when it switches from drive to reverse and vice versa. Sound is coming from the back of van. Does not make noise all the time. Drove 50 miles last night with no problems and minimal clicking. Could it be U-Joints going bad? Or is this a different problem?

1995 Subaru Impreza. Has died several times w/in last 3 months when slowed down to stop or park. Power dummy light comes on when it dies. Resumes back to normal by turning ignition off and back on again. Check oil/power steering fluid regularly. Added extra oil week ago, too much oil perhaps? Car has history of smelling like it's burning either oil/power steering fluid when operated at high RMPs (ie climbing hills/accelerating). Smoke sometimes comes from under hood. Automatic, doesn't shift down very quickly. I either go super slow to keep RPMs low, or punch it to try and get it to shift. Last night/today:loud/almost grinding noise from under hood, all dummy lights went on, then died, completely fuctionless. any speculations?

My car has been have overdrive problems for a long time while driving on the highway it will stay in overdrive as long as i keep my foot on gas pedal or brake or in cruise control as soon as i get on the highway. As soon as i go off cruise so does the overdrive and will not go back in till i shut the car off and start it right back up. It makes for a long trip. I had trany oil changed does not effect it at all.
