Re: Lifted Front Squirrely
Excessive bump-steer (tracking to small grooves or cracks) can be caused by any number of alignment characterisitics, most commonly; a lack of positive caster or insufficient negative (or excessive positive) camber, and the front wheels being toed-out. However, in your case the most likely culprit is the lift kit. As the front end is cranked up, the A arms droop down and the tie-rods follow. This results in the tie rods resting at a angle down from the center link thereby both shortening their outstreched length (toe'ing the front wheels in) and causing the vehicle to react more markedly to bumps, as now the front wheels will go from a toed-in position (at rest) to a toed-out position (under compression) and then back (on rebound). This problem is worst when only one wheel is compressed, such as following a crack or groove in the pavement when lane changing. Lowered cars experience much the same problem, but in their case it is because the tie-rods have moved up. On lowered cars the solution is to raise the steering rack (via offset rack bushings), or lower the tie-rods (via spacers). This only applies to rack-and-pinion steered cars, however, I imagine the same goemetry would apply drag-link type steering systems (if you could find a way to lower the center link). Everyone confused now? In essence, you're stuck. Ride quality may improve with some creative alignment measures, but don't expect it to handle like showroom stock.---what the hell, it's not a range-rover anyway (who needs good ON-ROAD handling?)............................that's why my motto has always been...................................
