Cutlass Death Wobble UPDATE! READ

Okay well some may know i have been fighting death wobble for 3 months now!

I have researched it to no end, my fathers a mechanic and we cannot fix this problem...

I have replaced:

Tie rod
TRE's
Track Bar
Upper/lower ball joints
Wheel Hub Assembly
All new lower control arm bushings
Tires dynamically balanced and rotated
Front end alignment (1/8th Toe-in 5* caster)
and put on a $90 steering stabalizer to mask it somewhat but if anything made it worse (MOOG SUPER TRAIL BOSS)

I HAVE NO IDEA WHATS LEFT!!!!!!!!!! Iam contemplating selling the damn things thats how frustrating its been.

Yea,that's pretty much the only thing you didn't mention, hah. When those other items were replaced, were the round bolt holes messed up to more of an oval shape? Just thinking even tho stuff is new, maybe there's still some slop. You try the obvious of some one turning the wheel back and forth while someone is under the front end looking for any time of play?

My 98 developed this bad months after the lift, then I put street tires in it and it started doing in everytime I got to 35, even on gravel. I took it to the alignment shop and it hasn't done it since. The very large Chevy dealer in Fargo aligned my dmax 3 times telling me everything is perfect until I personaly showed them that my rears where an inch closer in the front than the rear, with a tape measure, then they said yea your right your axle tube is bent. Try another alignment shop, by the way my grand has over200000 on it with all stock bushings.

Well upper bushings are often a cause.
motor mounts cause a similar experience.
Rear bushings can cause it.
bad tires can cause it.
Bad steering box

You've really only scratched the surface.

'97 zj 5.2, some stuff, some other suff, and some things that even work sometimes.

mine is still doing this too, been chasing my tail for the past few months. I think my next thing to check is the steering box, it is the only place I get any play. I might also change the front upper bushings, they looked fine when I changed the UCA's but again they are the only bushiungs I haven't changed.

steering box is good, i got my tires balanced and rotate them frequently they are not bad enough to cause my issue. motor mounts wouldnt cause my death wobble... if it was motor mounts it would stop after braking slightly and they woulkd have to be so lose to actually casue any issue and what rear bushings are you talking about?

I'd definitely get the upper control arm bushings replaced. I've seen people replace these bushings and have had their DW disappear because the bushing was so FUBAR'd.

my .02 cents...

Rear upper and lower CA bushings - Rear track bar bushings... Might check sway bushings while you're under there.

Jack up the rear - Use a crow bar to gently pry the CA's & track bar at the bushings. If they move in a way they're not supposed too, you got bad bushings.

Don't fear the regear.

Finished 4x2 --> 4x4 conversion.

He may not have moved the cam because when he put it on the machine it showed that it was in spec, maybe you got it right. The steering wheel not being straight is a big no no for any "good" alignment tech though.

hi i'm new here but have cured the worst DW anyone has ever seen. i changed everything i mean everything and had so much smoke blown up my A$$ i'm farting rings for life. the worst thing i did was buying "kevins track bar DW cure" what a joke. he sends you the softest bushings on the market and then charges almost fifty bucks for harder ones. anyhow i'm done talking about my poor investments let me tell you what fixed my DW 100% CURRIE 1 TON STEERING its not cheap but i promise its your problem. please don't put any more money into this problem until you get this steering.
