well like a year ago I got my truck lowered by some guy that has his own shop.. Well he really didn't do a good job at lowering my truck...when I go over a small bump on a road the truck shakes from the back... The truck is also hard to steer to the right..and wen I turn to the left it turns easy but if I turn it to much, at a certain point it the steering wheel turns by itself..wat do u guys thnk it can be?? Thanks for yall help..
