Another Death wobble thread but different set yp

[jsturges18]

23 gladiator sport s 30,000 miles

Clayton ride right 2.5 (adj front upper arms, f/r trackbars) Whiteline sways, Falcon shocks/stabilzer

fifteen52 17x9 on bfg k02 37x12.5

the Clayton lift went on per instructions (other than flipped uppers, whoops, shop fixed it) and the jeep had kenda Klever 35x10.5 on it.

a an authorized Clayton dealer shop offered bfg 37s installed and to adjust my suspension alignment properly. (Caster, pinion angle).

Clayton’s instructions say the front upper control arms should be eye to eye at 20 1/4” to get correct caster. The shop adjusted them all the way down closer to 19 inches saying this gives the proper caster. Since the adjustments and 37s my jeep now has death wobble at low and high speeds. I re adjusted the control arms to Clayton’s specs and the low speed death wobble is gone. High speed I haven’t tried but I believe it may still be there when hitting big bumps (Why bother with adj uppers if they are adjusted to stock length

the shop believes it to be ball joint related (common gladiator issue) However I’m trying to knock off easy things first. I’m getting a proper road force balancing done, I ordered mopar extended lower control arms and I adjusted the tire pressures down from the 40s to the 30s.

is there something I’m missing or any input from everyone’s experiences?
It’s weird that the shop says one thing but Clayton says another and the shop is a Clayton dealer.

also, everything underneath looks good and has been retorqued. I followed a few of the other threads to help find the issue and it truly seems like an alignment or wheel balance issue.

thanks for any help and input. I’m ready to move on from jeeps lol

Once the balance and alignment is checked I’d look very close at those ball joints again. Clayton may be telling you something but the shop is actually under the vehicle with their hands on it. Hands on diagnosis is much preferred than by proxy. Then it’s just the process of deciding what units you want from there. Did they check wheel bearings when they did all this too?
