Weird violent bump steer on HWY & road?
Just got my car lowered about 2 inch from stock. Went to get an alignment and the tech told me that I had a caster misalignment of about 1.2 degrees on one side. When I go to drive on the freeway or any bumpy road for that matter, the steering wheel would shake left and right pretty bad, but the car drives smooth and straight when on flat road. The car doesn't pull to any sides either? Very strange bump steer that I can't figure out? Any body know of any solutions...?

"If the caster is different from side to side, the vehicle will pull to the side with the less positive caster. If the caster is equal but too negative, the steering will be light and the vehicle will wander and be difficult to keep in a straight line. If the caster is equal but too positive, the steering will be heavy and the steering wheel may kick when you hit a bump. Caster has little affect on tire wear."
