Now if it isnt one thing its another

The other day I was driving in 4 wheel taking a turn when all of a sudden I hear these really load pops and bangs followed by my rig lurching forward each time I hear it. It feels almost like the CV shafts are slipping. It does it on both sides while turning hard but only in 4 wheel. My rig is currently sitting at 22.5 from the center of the wheel to the bottom of the flare. I have not had this problem before but I recently switched out my front springs with OME CRD HDs instead of the HD gaser. The shafts do not apear to be at any extreme angles and my boots are not torn. This truely has me stummped. Any ideas?
Thanks
