Shocks or struts problem

i have a 1998 malibu, it has an aftermarket lift kit on it. i having some problems now. when i turn the wheel, i hear popping noises. if i stand in front of the car, the drivers side front corner of the car looks lower than the passengers. also when doing a u turn, it feels as if the front tire on the drivers side lifts up. what could be causing this?
