50 mph shake on my E28

[Eric K]

I just replaced the control arms, thrust arms, idler arm, and all the tire rods on my E28 535is. I still on occasion have a shake in the steering wheel at around 45-50. What else could my problem be?

out of balance wheels? did u get an alignment when u were done?

agree with the wheel balance bent whee/out of round tire deal. also tighten the nut behind the wheel and check the linkage between the wheel and steering box. any play will cause this.
