1995 Bmw 740i Shaking Problem

When I drive my 740i over 40 Mph the streering wheel wobbles and it becomes worst if i were to hit a pot at during those speeds. I went to an authorized bmw service center, and they couldn't find the problem. My tie rods were good, i changed the center links, and it still skakes. Any suggestions as to what the Problem may be?

The upper control arm bushings (sometimes called thrust bushings) are prone to failure on our cars and one of the symptoms is the shaky shaky at speed. I would have these checked out and if repalcement is needed I would suggest the urethane replacements.
