Steering judder - PAS pump?

[puglove]

Sounds like it could be a number of things, first off just because the pump is only now and again means nothing i had one like that on my old DT and i thought it would be on untill i saw it in my rear view bouncing down the road followed by a trail off steamin oil lol

but yeah could be wish bone bushes, top mounts, cv's, shafts, rack etc. you need to get it up in the air wheels off and give everything a wiggle, and check for loose bolts aswell
