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..

What did he install to lower it? It sounds like the suspension is out of square. Measure to the centerline of all four axles and measure diagonally from left front to right rear and right front to left rear. Make sure wheels are perfectly straight. A plumb bob helps a lot for marking the locations. I'd put it on stands, take all four tires off and then use the plumb bob to put a mark on the ground on all four corners to measure. Use paint or something that will be permanent, for a while. Be sure you put the stands under the axle and a-arms to simulate a load while the tires are off the ground.

Yep or major caster flaw in the front.
