Ok here is my dilemma. I have this vibrating noise I can hear but whenever I take a hard turn it will go away until the car flattens out again. It is suspension or maybe some sort of drivetrain mount?

 

Where do you think it's coming from? Whatever it is could be loose and just simply getting slammed to a wall or something under the lateral G's, thus stopping the vibrating.

 

It definately sounds like its coming from behind me.

 

Probably rear wheel bearing or even a tire. Does it change pitch with speed?

 

i have sorta the same problem... the other way around.

when i turn i hear a knocking sound. but not from the back but like near my right thigh. its comin from the tranny. is this bad?

 

that really sounds like a bearing to me also.

 

the other thing might be a u-joint pain to replace. Does it do that when you start or when you let off the gas and puhs it again?

 

mine does that.....just when u shake the car fast........it will make a knocking sound..

 

what about a differential bearing going out. That's what I figure my slight clicking and humming is coming from. And mine is definitely coming from the rear.

 

Change your fluid out with some good Royal Purple or Redline fluid. That should help eliminate the problem if the wear isn't too major. It helped quiet my rear-end down alot. You only need two bottls (1.3qts to fill it) which comes out to $16 on average.

I would also check the wheel bearings.

Jack up your car from the rear, grab the tie from the top and bottom, and try to rock it forward and back. If it jiggles, the bearing is probably shot and will make a sort of howling noise that changes pitch with speed.
