1. Welcome to

2. There's a search button that helps with common problems like these...There are TONS of DW threads.

3. +4 caster is too much. also, check TRE's and trac bar. Take it to the alignment shop if you havent done so after you installed the lift. Good luck!

Sounds like your track bar could be bad, have someone move the steering wheel back and forth while you look at both ends of the track bar and look for any play in the ends. As far as caster here is a good site that gives some caster angles campared to lift.
