I have a 1996 (N REG) Discovery TDI, bought in 2006 and has now done
127K+ miles. Handled fine when I got it but started to experience wheel wobble and swaying at higher speeds, with the speed at which the problem occurs decreasing over several months.I have replaced the steering ball joints and track arm as it was so badly seized the tracking couldn't be adjusted. Replaced the wheel bearings on both sides Swivel preload is correct, drivers side swivel bearings have been replaced. Steering damper is operating correctly. Front shocks have been replaced. Tracking and wheel balancing has been fixed. The wheel wobble has now almost completely gone.
But the swaying is still present especially at acceleration and most noticeably on cornering to the left. The vehicle leans to the left slightly when at rest. I have tried to test the bushes on the panhard and radius arms with a lever but can't feel any up or down movement, there is slight movement left to right along the fixing bolt on the radius arms at the axle, is this normal? I haven't been able to test the antiroll/sway bars or connecting joints. Could these be a problem? Are there any further tests I can do to try to determine the cause?
Thanks for any suggestions
Ben
