i have a 2 inch body lift also, and NO bl doesnt cause wondering, i'd be willing to bed the trunion bearings are toast, my truck started the wondering a few years ago, i put some good used trunion(knuckle) bearings in and it quit
Worn out spring bushings will cause this too. 3" BL can cause problems with the 4wd shifter staying in 4wd if the floorboard isn't clearnanced for it. I'd test it before a wheeling trip.
Where are you located krash? Someone may have a set of used lift springs in your area for cheap.
