Baz2236 Posted June 18, 2012 Share Posted June 18, 2012 my 90 is running OME 2 inch lift shocks and springs polybuushed all over. But when i drive down the road and hit bumps where the road is not quite level i have to keep correcting the steering, on a flat road its fine just when there are bumps. The wheels are balanced no vibrations through the wheel it just dont want to go in a straight line. After it hit a bump. The swivels have been replaced and bearing checked and adjusted but it still like it. Any ideas where i should start looking. Baz Quote Link to comment Share on other sites More sharing options...
Eightpot Posted June 18, 2012 Share Posted June 18, 2012 Take it you mean a tendency to wander slightly rather than a shimmy as you go over bumps? I think raising the suspension does make this a little more of a tendency, but you might want to check your steering box for play and panhard rod bushes and bolts aren't worn. Not enough steering preload can increase wander as well. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted June 18, 2012 Share Posted June 18, 2012 Kingpin preload (or lack of through worn bearings) can cause this, but with the lift you also have the wrong caster angle, plus all the bits Eightpot mentioned. Quote Link to comment Share on other sites More sharing options...
danebrewer Posted June 18, 2012 Share Posted June 18, 2012 all of the above points, but also think about the steering damper, I had the original oil unit on my 90 and it was a bit swimmy through the bends and over potholes, I put a new Bilstein B6 gas pressureised damper on it and it's really firmed things up a load, obviously there's room for improvement but it's certainly helped a lot.

Baz2236 Posted June 18, 2012 Author Share Posted June 18, 2012 Thats me sorted this weekend then I will check the preloads should it be tested with or with out the swivel seal on. Quote Link to comment Share on other sites More sharing options...
