Hi! I have 2 mk1 rwd escotrs . When crusing at any speed the stearing wheel starts to judder/shudder. I have replaced the lower controllarms with balljoints and bushes and stabeliser bushes. the stearingrack have no wear. I also fitted a stearing damper wich helped a bit and tried difrent tyres and mags. What else can cause the problem???
