Hello guys. I have a 1989 240dl. About a month ago I notticed that the brake dust on the driver side rear wheel was 10x more than the rest of the wheels and when driving slowly I could hear a swish swish sound ever time the wheel went around. So I decided that maybe the rear rotor was warped or something. I got a new rotor and some pads. Went to put them on today and noticed when I took the old rotor off that there was a lot of grease all over the e-brake. Now when I put the new pads in and spin the rotor there is a wobble to the rotor. So is the driveshaft bent or do I need new rear wheel bearings? What should I do or look at next? Thanks for the help.
