I have a whining sound that seems to come from the rear of my 06 manual coupe. It only does its while the car is moving. It doesnt matter if its in gear or not and it goes away after i drive the car for a few miles. I just replaced all wheel bearings and it didnt fix my problem. Any ideas what it could be?

 

Without hearing it my best bet is it's coming from your diff

 

Yeah i know. Its hard to describe sounds. I figured it was the diff but i dont know much about them so i didn't know if there was anything common that could go bad

 

How many miles on your car? Has the Diff ever been flushed? How does the rear diff bushing look?

 

112,000 miles and i bought the car a year ago so i doubt it has ever been flushed. I need to get under the car and look at the bushings still

Do these pics help out with anything?

 

Just did a diff fluid change so we'll see what happens

 

I get the same sound with my car. I think it is the diff as well. I have changed the fluid and it did not go away. Doesn't seem to cause any problems...I think its just the diff being cold as it goes away after a few minutes of driving.

 

My diff made no noise with amsoil fluid. But I only had 68k on mine

 

It's the diff. Not cheap....

 

Well im sure the whole diff isn't screwed. It just need some maintenance right? Maybe a seal and bearing kit?

 

If it sounds like a flying saucer, you need a new ring and pinion. It COULD be a bearing but not likely.

 

Well i drove it to work this morning and it didnt make any noise at all. I dont know if changing the fluid worked but i guess time will tell
