My 300tdi 110 wagon had developed a shudder in the steering that occurs at around 105km/h. At lower speeds there is no hint of the problem.
The shudder starts when I hit a smallish (well smallish for Australian highways) bump in the road and it rattles the steering wheel very uncomfortably until I reduce speed. I have replaced all the dampers, including the steering damper, and it has made no difference.
All wheels have been balanced and the alignment has been checked.
It has been suggested that it may be the radius arm bushes, or the pitman arm. The steering tie-rod ends are slightly worn, but not flogged out.
Has anyone had a similar problem, and if so do you have any suggestions regarding the cause?
Any assistance will be appreciated.
Regards
