So, I changed out my drag link ball joints seemed to improve for a while but the wobbles are back. I have narrowed it down to wheel alignment and tie rod ends stuffed. Will try some toe in when I get home and change out the stuffed tie rod ends

Perth Patrol fitted new draglink and damper wobbles gone

Never had death wobbles. Just a shimmy. New tyres fixed it.
Must grease the king pin bearings one day.
Drop boxes and 3 " springs as far as suspension mods.

I'd be checking your panhard rod bushes properly first, if you get the death wobbles. I'd bet money they cause the majority of death wobbles. King pin preload really just gets rid of an annoying shimmy after balancing etc etc is checked.

You don't have this issue warthog. I'm speaking generally.

Yeah I've never had them apart was all. I wonder how they are going.

Had the wobbles around 80kmh but not bad. Adjusted tough dog damper up 2 notches and gonesky

Mines fixed, whooo hooo, had a wheel balance and a tow in adjustment and it's gone, surprised me I was convinced I was going to have to adjust the top swivel hub bearing. I dropped it into BJ's for a wheel balance and check just to eliminate the possibility and now it's fine, when I look back it seemed to happen around the time the Eaton was fitted and the wheel bearing seals and swivel hub seals etc were done, so now I'm wondering whether a wheel weight was dislodged during the work.

Anyway I can start my 12000k trip without the bloody wobble, if only everything was that simple to fix, as said next step was going to be upper shim and panhard bushes.........

So far I have changed out front and rear panhards, tie rod and drag link, all from superior.
Caster bushes are 10,000km old
Tyres are 500km old.
suspension is old man emu 2" at 25,000km old
I have removed most of my wobbles, but they are still there, especially under braking. I suppose I am up for new rotors, wheel bearings and king pin bearings.
Any other suggestions?

What caster do you have?

 

[risms]

3 degree I think. The mechanic did them. Proper rubber bushes

Cool, that's fine. You mention wheel bearings, are they loose? also remember not enough preload on the king pins can cause an issue.

 

[risms]

That is my next stop. I have not properly checked them and want to reset the preload. King pins will be set at the same time.
I want to replace my wheel studs and rotors so while I am in there why not go the whole hog

I chased this, the 85km/hr wobble. Wheel bearings packed, wheels balanced, steering box lash, new tyres--it would seem to go away then return. Then I found the chassis was rusted through on the bottom inside of the box section where the ac drain is. Had to be underneath looking back out to spot it. Chassis repaired, problem gone.

Wow, you must have had some serious rust and some serious chassis flex, that is a quite an unusual issue.

 

[risms]

im scared now. if you need me I will be underneath my car with a high powered torch

The ridiculous part was, it had just been over the pits. I'd copped a yellow sticker for a cracked windscreen I should have replaced, and the inspection had shown nothing major. But one item was a bent tie rod ( on the same side as the rust)--this was almost imperceptible, and the bloke who inspected it must have almost been looking directly at the affected area. It was only spotted by the mechanic who was replacing the tie rod. I got the phone call..."better come and have a look at this" . it was right through in numerous places on the lower corner of the channel, over about a length of 150mm. But only right in that corner, you could only see it underneath and looking out.
I had it repaired by the local panelbeater and put it back over the pits. Forward two busy years, and I get under it again and find the rust had spread, he hadn't got it all. Bigger repair this time, done properly, and replaced from near the top of the wheel arch downward sweep to the gearbox crossmember mount. Cost $2400 from memory.
At the time, the repairer reckoned he'd seen a few rust in the same place, when the AC drain was running into the chassis. All the rest of the chassis checked out OK on thorough examination, but it has always been obvious this old girl (395,000 now) has had a hard life.

So, just tightened up the steering box to take out the play. Only tightened less than a 1/4 of a turn. See how we go. The wobbles are starting to get to me lol. If not this, then king pins and shock rebuilds coming up.

Update: better but still terrible.

Was reading a post the other day about adjusting toe to be slightly out with bigger rubber?? I would have thought toe in. Anyone care to shed some light? My drivers side amada extreme shock is stuffed (leaked oil) so that's probably not helping and I'm not sure how old the king pins are

91 TD42 with a 2" lift. Has had all sorts of shimmys and shakes that gave been improved/worsened though wheel balances, new bearings, rod ends, etc over the years.

DEATH WOBBLE - an entirely different thing. How I've generally seen this described (and how I've experienced it) is when something like a bump in the road or reaching a certain speed triggers a big amplitude 'wobble' through the front end. Literally the steering wheel almost flies out of your hand and it feels like the front suspension is ripping itself apart. First time it happened I thought a wheel bearing had let go or something. Impossible to drive with and you have to immediately slow right down to make it stop. Your passengers will want to get out and hitch hike home.
In my case, replacing the panhard bushes fixed it immediately (thank god). I have heard of this as the most common death wobble fix. The old bushes only had the tiniest amount of play but sure enough that was the problem.

I feel like some of the wobbles people are talking about here aren't the actual dreaded "death wobble" which, as the name implies, feels like your front diff has come adrift and your about to die. Big difference...

have to agree with you there I don't think a lot of people have felt the real death wobble

Death Wobbles has been a generic term used over many years in many threads, the idea of this poll and thread was to find the common causes of 'wobbles' (apart from wheel alighnment as explained earlier) generally so that members new and old could formulate a plan to solve them.
