i bought a short bed frame from a junkyard and someone had already done a sas on the truck so i bought the front axle with it.... they had a 6 inch lift but did not buy radius arm drop brackets the just welded the original brackets to the frame...im guessing they just bought the 7 dagree c bushings...i had a 6 inch lift on my old truck and when i swaped the frame i used my drop brackets so it looks like the caster is way in the positive... i checked all the tie rods...ends.. trac bar mount bushings.. bearings.. ball joints..took the truck in for alignment they said the camber was good.. so i guess what i am asking is it possible to have to much positive camber...and is the what is causing my death wabble... it starts around 25 to 30 mph i will post pics tomarrow

 

Scary isn't it.... been there. Possibly the tires need balanced if your sure everything else has been checked. The bigger the tires, the bigger or worse the wobble is. Usually track bar or tires.
