Hi.. I have a vibration when turning, more prevailent when turning with a dip, both right or left and with a more agressive turn rather than a simple turn. I have had my steering damper and tierods replaced but it is still there... almost feels to me like the powersteering pump under stress. Any ideas what it could be? Thanks in advance for your help.. CB

 

My 560 does it too but since i dont drive the car everyday i dont worry about it but i think it is the pump.

Maybe sleepwalker can give us an idea.
