Death wobble

[coldtaco]

So, I drive 4300mi with no issues with the death wobble. Couple of days ago I replaced the front spring bushings, which where shot. Yesterday I drive around town, up to 65mph and all is fine. I finally head home and around 50mph I get the death wobble starting, so I slow down and pull into a parking lot. I re tighten the front lug nuts since I removed the front wheels to do the bushings. One side took a little tightening. Then drove home not going over 50mph.
This afternoon I replaced the rear spring bushings and go for a drive and the death wobble is still there starting about 50mph to 55mph. Didn't try to see if I could drive through it.
Checked the front wheels for excessive play and did not find any.
Thoughts?

Oh yeah this is on the HJ-75

Try rotating tyres front to back if that don't work climb under front as someone rocks the steering wheel back and forth while you inspect all the tie rod joints. Next jack up front Axel and wheel checking the king pin bearings with top to bottom movement.

Rotated tires, lifted the front checked for any play non found. Don't know the age of the springs, but the bushings where not original, but pretty toast. This happened at two different roads.

What bushes are you running rubber or polyurethane

My experience is that virtually any play anywhere in the front end results in death wobbles, so tie-rod ends, drag link ends, wheel bearings, swivel hubs, loose u-bolts, king pin bearings.

Trail Taimer bushings

Trail Taimer bushings

?????

What ever their called

What ever their called

Allow me to interpret .....
Ward wants to confirm that the bushing were indeed manufactured by Terrain Tamer. Do they have the Terrain Tamer name or logo on them?

 

[coldtaco]

Yes

Sounds to me check you trunnion/knuckle bearings. They are held in so tight, until you pull them you can't
tell they are shot. IMO

 

[coldtaco]

Swapped the spare with one wheel/tire combo that had the most out-of round. So far seems to have fixed the problem

 

[Bob Richards]

Wonder if you threw a weight?

 

[coldtaco]

The wheels have been balanced twice so far by two different shops.

it's back with a vengeance. :-( Still nothing that I can find that is loose. Ordered a knuckle rebuild kit. I guess that would be the next step.

you need to replace the tyres if they are out of round they will be out of balance mate

Forgive me for asking simple and obvious questions, but just part of the elimination process.

It started after swapping just the front spring bushings, correct? You said terrain tamer, are your springs terrain tamer? What springs are you running?

Have you jacked up the front end and grabbed the wheels and checked for play in the wheel bearing? Given that you had no DW prior to swapping Bushings, it seems like the obvious culprit. My guess is that they are the wrong size.

 

[coldtaco]

Replaced front and rear. Where suppose to be the right bushings according to the shop I bought them from.

Just a thought, could you balance the wheels while on the truck?
