Jack up front end, put on jack stands, grab tire and check for play top to bottom (grab tire at 12 and 6) and side to side (do same at 9 and 3). Think top to bottom is wheel bearings, side to side knuckle bearings.
When its wobbling have you push in the clutch to check its not driveline related? (longshot).
Well the death wobble is no more. JP and I pulled off the leaf spring and realigned them and put in a new center pin. Then last night and this morning I put in new bushings and put everything back togther. It's amazing how nice it drives now, especially with new bushings what a difference, oh yeah and the fact that my axle is where it is supposed to be now. Thanks monkey boy for the help!
