Re: Wobble
Just wanted to say you all saved me a bit on this thread.
My TJ was having some DW issues. I had it toed out to compensate. I took it
to the front end shop and they did an alignment. There was still DW. After
reading the print out from their machine and reading this thread, I noticed
the castor was set at 3.5. Yesterday I went out and gave the bottom two
control arms 2.5 turns out. I drove it all day yesterday with no DW issues.
A big thanks.... The new owner of the TJ is flying in from Las Vegas
tomorrow and I was having a cow, trying to figure out how to explain the DW
to him. Now he can have a nice drive back. For some reason I didn't think
there was a link between castor and the dreaded DW.
Have a great day.

Re: Wobble
Insufficient Caster (not castor, which is like Castor Oil) angle can
contribute to death wobble and other problems like twitchy steering and poor
steering wheel return-to-center.. But do check two other things too because
they can trigger death wobble while insufficient Caster angle usually only
lets it fully develop. Carefully check the passenger-side trackbar mounting
bolt for tightness, it should be at 74 ft-lbs, and double-check the front
tire balance. Both of those are also major contributors to death wobble,
especially a loose trackbar.

Re: Wobble
The guy that did my alignment checked the trac bar, doesn't mean I shouldn't
double check it.
The tires probably need ballanced, they always do. Tires usually spin around
on steel rims, chunks of rubber usually fall off while off roading and
weights usually come up missing.

double check it.
The tires probably need ballanced, they always do. Tires usually spin around
on steel rims, chunks of rubber usually fall off while off roading and
weights usually come up missing.

Re: Wobble
This is all interesting. After my lift I noticed, very subtle, a slight
steering pull one way and then the other. Not death wobble at all but a
little disconcerting. I chalked it up to 4.5" of lift (plus 1" body lift).
But now I think I will check all the things mentioned here. Thanks Jerry.

steering pull one way and then the other. Not death wobble at all but a
little disconcerting. I chalked it up to 4.5" of lift (plus 1" body lift).
