I just replaced all my rotors/pads all the way around on my 1991 BMW 318is. Afterward, I was on the freeway going to my buddies house and at about 75 MPH in 5th gear, I noticed a shaking from the rear. I didn't think much of it and after driving about 80 miles I checked my wheels and 2 of the lug nuts on the rear driver side wheel had come loose (they were twistable by hand). I rechecked all the lugs all the way around and tightened them back down. Then, just last night I was going to the same friend's house and it vibrates still, but a different kind of vibrating. It gets extremely violent when I go from 80-90mph. If I keep it at 75 it's hardly noticeable. But now the wheel makes a high pitch scratching sound (like a squeal tab on a brake pad).

Bent hub? Bad wheel bearing? I haven't taken the wheel off to look because of the weather. I'd just like to see what someone else thinks.

Thank you!

when ur tightening ur lug nuts try to roll teh car a little before the final torque.
also maybe u bent something when ur wheel was loose? bad wheel bearing would make a gridnign noise at low speed.

I just got back from my buddies garage and it seems that the rotor set screw came loose. It actually dug itself into the inside of the rim, and now the head of it is destroyed. I tightened it as much as I could and put lock tight on the lug bolts to keep them from loosening up again (they were loose), but the rotor is still slightly moveable. I may need to drill out the set screw and retap the bore for a new one.

If I had a torque wrench, none of this shit woulda happened. What a bummer =(

Yikes, that's bad.
Note to self....buy a torque wrench.

Thanks!!
