Thanks for the thought, Boris. But count yourself lucky. For the benefit of others who may be following this thread, I ought to say (for the record) that this is not the problem, or the solution, with my DW. I'm sure it's true that worn tyres, especially if out-of-balance, can cause a "wobble". You might notice this and find it worrying. But as many Jeep owners know, the really horrible change-your-trousers-DW-from-hell is so severe that it is another league altogether.
Also, I'm on my third set of tyres, all standard size. The first were the OEM Goodyear Wranglers. The second were Toyos. The current set - which are not worn out, and have just been re-balanced - are Michelin Synchros.
Just to check the tyre issue, I changed the front ones and put on spare Toyos that I still had. Made no difference: the DW still struck, and still tried to shake the axle off the chassis and my arms out of their shoulder sockets.
I feel your pain. I feel your pain.
My story:
I have a heavily Modified 96 XJ.
I have owned it since 2004, and I lifted it in 2004 with 73k miles on it. Most of the modifications were done then.
Now with 150k miles on it I had a bad wheel bearing for inspection (this is my fourth bad wheel bearing in the past 7 Years because of large tires)
The only difference is this time...
once the wheel bearing was replaced. I have had death wobble.
so. Not one to stand by and scratch my head. I went right to work.
Looking at some of the old lift parts I found some slight wear in the bushings of the control arms. so..
This is what I replaced, (and I'm sure you can see the $ signs stacking up or ₤'s in the uk right?)
JKS upper control arms
JKS lower control arms.
TNT Heavy-duty track bar
JCR 1-ton Heavy Duty Steering (UTK)
JKS sway bar links.
Replaced the front 5.5" RE springs
UCA axle bushings.
Re-enforced axle mounts
Then I did the tires to the back swap to see if it helped.
Took the front drive shaft out to try to reduce drag on the front tires (WAG)...
adjusted caster to 0deg
adjusted caster to 4deg
adjusted caster to 7deg
adjusted caster to 9deg
Then went to negative caster -1, -4, -7... (fyi, it gets worse when its negative...and there is no return to center.lol)
adjusted air pressure in tires.
adjusted toe in to 0
adjusted toe in to 1/8"
Now I am sitting here with basically brand new front suspension.. and death wobble.
(the ball joints were replaced on mine in late 2006 and still appear tight, but I'm not ruling them out just yet.)
Tomorrow I am going to put some new shocks on the front.
and Mount a steering stabilizer (I have not run a stabilizer since 2006..)
Something is amis... and its IMPOSSIBLE to find.
HOWEVER get this...
one other weird symptom. Just sporadically, when turning right on full lock, there is a nasty recurrent noise from somewhere down on the LH front. More a crunch than a click: I can almost feel it through the soles of my feet. If the UJ hadn't been replaced, I would suspect it, but then again, a UJ makes a clicking sound all the time on full lock if it is bad. This noise only occurs some of the time. And I can't make it happen in the workshop when wiggling/turning the wheels or the steering on the ramp. So where might this noise be coming from?
I have that... I can't find it.. but I have that... same thing word for word..
