2WD popin in the front of truck

[sonoma_extcab_98]

I have a '98 sonoma sls 2wd 4.3L. I have recently added a 2" suspension to the truck. Moog lifter coils 1.5" plus 1" spacer on top. The rear has new shackles that raised it up 2". About 2 weeks after the lift the front end has started to pop and sqeak really bad. The ball joints were good when we checked them.. It sounds like it might be the frame, or the steering but not sure. Anyone have any suggestion on what it is, and what I can do to fix the problem. It only does it at slow speeds anything below 30mph.

a guy at work was telling me that my factory shocks could be bottom-in out. Is this possible.
