So after swapping in new axles i ran into death wobble after running them for a few hundred miles, at first it was fine. I have no stabilizer or sway bars, and i just recently re torqued and cotter keyed everything up front to spec.
the front axle is a 96 D30HP pretty much all new everything... 4.56 gears, Detroit True trac, spicer 760 u joints brand new, trussed, outer c gussets, lower c gussets, lower control arm mini skids,wj knuckles with jks adapters, new timken unit bearings, all new brakes, new balljoints upper and lower spicer and moog lowers for the wj swap. 1.50x .250 1 ton OTK steering with chevy TRE's, JKS OTA bracket, IRO double shear trackbar shortened for OTA, good bushings. RC lower control arms with new bushings for 4.5 lift, stock uppers that were reinforced and new bushings. New tcase mount and browndog engine mounts. New 35 mtrs. durango box with a reinforced spacer that ties into my winch bumper drag link and track bar are pretty parallel also and im running a SYE.
The jeep feels a little shakey sometimes when i get up to speed around 50ish or so i believe like the beginning of death wobble and if i hit a bump at the right spot it will death wobble, specially if i hit a bumper in a slight turn. Being that literally almost everything on the front end steering and axle related is new i think it could only be a few things.
Im debating on getting adjustable uppers or just long arms if i can swing it because im curious if my caster is causing this, not sure how to measure caster correctly but with my angle finder against the flat spot on knuckle below balljoint it says like 9 Degrees which is probably wrong. I also want to find a way to mount a stabilizer most likely just to help some even though i know it shouldnt be needed. Im going to look over toe-in again also, i even swapped steering boxes and it didnt help. The steering itself just feels crappy to me kinda wonders a little if you dont keep on playing with the steering wheel while driving having to shimmy side to side alot with the wheel, also not used to no stabilizer, dont know if thats why it does it. Any input i need this thing for winter and trying to figure it out before weather gets crappy.
