Greetings,

I just installed (uneventfully) new rear subframe bushings on my 87 300SDL (126) yesterday. The nock-kneed geometry of the rear wheels looks better now, but I seem to have developed a new problem.

There is a distinct rumbling coming from the front (right?) axle area at any speed over 30mph. It sounds like a bad wheel bearing, but that seems unusual to develop over night. I jacked that side up and spun the wheel and checked for play, and everything seemed ok. (I know I need new tires and probably lower ball joints and an alignment, but there was no problem yesterday as far as noise goes on a 200 mile drive.)

At highway speed, the noise was loud enough for my wife to notice last night.

Anyone have any ideas?

I am thinking that the new subframe bushings have changed the alignment of the front tires enough so that the rubber/tread is having to adjust to a new loading pattern. If so, it seems like this might go away.

But if anyone has any advice, please let me know.

alec
