Hi. I'm new to the forums and I have already found a wealth of info here! I recently acquired a 1990 535IA with the cold weather package for an excellent deal, and I have to say I love everything about the car, except this noise and a weird steering malady. I'll try to explain this the best I can. I have a weird noise that coincides with the speed of the car, I put it in neutral while driving and it has no effect on the noise. The noise is hard to pinpoint but when you are sitting in the drivers seat it sounds like it's coming from the passengers side, if you are in the passenger seat it sounds like it's coming from the center of the car right under the center console, and you can feel it through the shifter. When I first got the car it would only make the noise during high speed left turns. Now it will make the noise going over bumps and going straight. It almost sounds like the tread of the tire rubbing on the inner fender, but I pulled all 4 wheels off and couldn't see anything hitting.
The noise gets louder when i turn left or go over bumps, basically when the front right spring compresses. This is what led me to believe something was rubbing the tire. I can't stand the noise anymore and it only seems like it's getting worse. Any help or suggestions would be greatly appreciated.
