This is all related to a '95 540i automatic....

So...I wrote a while back about a shake that I thought had to do with having the style-5 e39 wheels on an e34. The most common shake is because people haven't put hubcentric-rings on...and get a nasty- "my wheels are going to shake the hell of the car" -shake around 50-55.

WELL...I bought the rings. I went to put them on...and there were some already on there from the previous owner! Sooooo, after spending around an hour with a suspension guy...balancing every tire...and looking for significant wear on the suspension...we still don't know what the shake is from...

The clues: it's in the steering wheel (not in your butt), suggesting it's in the front. Also, it stops when you hit the brakes...or starts to stabalize...

ANY IDEAS? Pleasssse help....

Upper thrust arms.

warped rotors? How old are yours and what condition.

Upper thrust arms or the steering nut is loose in the footwell.

Rotors are in great condition...Anyone else think it's the upper-control arms? aka thrust arms???

i replaced my thrust arms about a year ago. and tightened that bolt below up the footwell. i had the same shake you do. it sounds like thrust arms.

Mine is shaking also, and I've replaced the thrust arms, etc.
