death wobble after explorer 8.8 swap and 1 piece shaft swap

[coolboarder1231]

i got a 97 ext cab, did the explorer 8.8 swap w/ explorer springs and than soon after swapped in a 1998 and up 1 piece driveshaft swap, right after the new driveshaft was in i started to get the worst case of death wobble, im pretty sure its coming from the rear not the front steering because when it shakes the steering wheels is normal and my stick shift vibrates violently until i slow waaaay down. i've never had this problem before with any of my lifted rangers, anyone know what could have caused this? thanks stu

oh and i set the pinion angle at 6 degrees and the truck has 4 inch blocks, no factory 4x4 blocks, and the explorer leafs

Is the rear square to the front? Cause no reason for death wobble to come from the rear.

Only things that come to mind are, out of balance driveshaft, loose lug nuts, bent axle shaft, or it could possibly be dirt on the mounting surface for a rear tire, causing the tire to wobble.

Driveline vibes, but not Death Wobble... DW will make you crap your pants and the steering wheel all but rips out of your hands at speed. Not DW if your steering wheel didn't move...
