I have a 1987 300E (not 4matic). When accelerating, the car pushes to the left. When I let off the gas, it pulls back to the right. The pull back to the right can be quite sudden and a little unnerving in bad weather. The more power being applied, the more noticeable this is. It feels like one of the rear wheels is moving under thrust. If I had to guess, I would say it feels like the right rear wheel is being pushed backward.
I have had the car on a lift and checked the bushings in all those arms that hold the rear wheels in place. There didn't seem to be much movement to me. I have also had a 4 wheel alignment and the print out shows the toe is very good on all 4 wheels. None of the brake calipers seems to be binding.
I think that one or more of those arms in the rear need to be replaced. Is there any way to figure out which one(s) are worn out? Could something else be causing this problem?
Thanks,
Robert
