grinding in rear...

[saturnine_sweet]

I have a loud grinding noise in the rear end. It increases with speed, and is higher in intensity if I am giving it a little gas vs coasting, at comparable speeds. So far, my ideas are a drum brake issue, a differential issue, or possibly a u joint issue. I have not been able to pinpoint if it is coming from one side or the middle, though if it is coming from a side, it is the passenger side. Any advice to help narrow it down? Any other symptoms I should look for that might help narrow it down?

could be u-joint or gears... be carefull not to really mess anything up. If you don't know what you are doing, take it somewhere that can atleast tell you whats wrong if you wanna try and fix it yourself.

Re: grinding in rear...

well, Ive not even looked at it much yet...just was looking for some ideas to narrow it down and save some time...though I think its the brake drum, now. Checked the temp on them when I got home from a drive, and the passenger side one was cooking. So Im guessing either an issue with the drum or the e-brake?

Re: grinding in rear...

So it happens when you are on the brakes... gas... or does it happen no matter what (on gas, on brake, and happens when coasting)

Re: grinding in rear...

happens all the time, a bit louder when I am giving it gas...to be honest, Ive suspected brakes more than anything, because it sounds exactly how a scraping brake sounds...however, since Ive not dealt with anything of this sort in this particular car, or with drum brakes, for that matter, I figured the more info I had specific to this car before I put time into, the less time I'd end up spending ;) That, and my handy repair manual mentions the differential and the u joint for that symptom, not the brakes. Of course, that thing sucks more than it helps, but I like to cover all the bases.

Check the rear wheel bearings.

Check for the oil in the rear differential just to be sure there is some in there. As for the drum brakes I don't think that can be it, because they would make a SHHH sound when you drive, or maybe will jam and the tire will not go forward; had that happen to me in a 93 caprice.
