death wobble woes

[89Burben]

ive searched, and wrenched, and have drew blood, sweat and tears.....just wanted to see if anyone had any other suggestions....

its an 89 sub 8" superlift springs high steer, one steering stablilizer,just replaced the plastic cone and spring on kingpins, brand new tre's, have the alignment toed in an 1/8". this didnt fix it so i took out the aluminum shims to change the castor somewhat back to stock and it still didnt fix it. Am i changing the castor in the correct direction or should it be shimmed more up towards the transfer case?

this happends with 31" tires, 38's and 40's.......

help palease

Are you using crossover steering?? If not, that could be much of the problem.

you need to put fender washers under each cap

im using high steer

you need to put fender washers under each cap

even since the springs and cones are new??

Yes...there isn't enough king pin spring pre-load to keep the bushings firmly on the king pins. Home depot sells 1/2" fender washers. They're 1/16" thick and 2" in diameter with a 1/2" hole. I used two per side and have no death wobble, that's with unbalanced 39.5's.

Try one per side first and if you still have DW try two per side. They're easy to install, cost next to nothing and cure the problem...

alright but what doesnt make sence is that i have 31's on the truck now, and its doing it like crasy....

i put in a 1/8" washer on each side and it seems good, no wobble, but it might be too thick of a washer b/c when you are turning, it doesn't like to turn back to center so im going to try to get those 1/2" fender washers that are 1/16th of an inch thick...


thanks!

yeah but for a possible cheap fix id say its worth a shot from what i've been reading.
