Grinding in rear only under load
This is my first post, I've seen a few other threads that have similar problems but they weren't quite the same and they haven't been updated for years.
I have a 94' that I bought VERY used. 260k, I've been swapping parts here and there but I have a bad grinding now.
The grinding is coming from the rear. It sounds pretty centered, but it could be either (or both?) of the bearings. The interesting part is that the grinding only occurs when I'm at the bottom of a gear. When the car is coasting or under a lighter load, there is no grind. When I'm at the bottom of a gear and there is more of a load, it grinds like crazy. It doesn't seem to be in any way connected with speed, as whenever I coast it is quiet.
My shop thought it was a bad bearing, but I'm not sold on that one.
I checked the u-joint, and there isn't any play. I'll take another look when I can get the wheels off the ground again because I'm really hoping it's just this.
Any ideas will help.
