Noise from the rear when off the gas, what is it?

[Guest Anonymous]

Im taking a random guess on my differential. Ive searched for it and finding out that a whining noise from the rear is the end of the diff. Anyways to put it in my words, it sounds kinda like metal constantly rubbing on metal, except when im on the gas. Its been doing it for a while, but it used to not be loud at all, so i just ignored it. But since ive been back from vacation its been alot louder. Can anyone tell me what this is?

Thanks

Apart from the differential, it may be the driveshaft centre bearing. Before tearing the differential out, put more preload (push the centre bearing mount further toward the front of the engine)and see if this reduces or eliminates the noise. If so, the bearing is bad. Driveline noises are REALLY tough to diagnose, as the problems manifest themselves by making noise in places other than the real problem. If possible, get the car up in the air, run it in gear, and listen from underneath.

Good luck...

both of my front wheel bearings trying to get rid of a grinding noise. I was ready to replace the rear ones (noise didn't improve after changing the front bearings) when a frind of mine pointed me to a shot (I mean SHOT) Center bearing.

I agree with Edward, put her up on stands and "listen to her".

Good luck!
