Re: Wobble
I had a front end wobble that was bad enough I stopped to make sure a
wheel wasn't about to fall off.
Drove me nuts changing parts trying to nail it.
Turned out the clutch on the rad fan had gone bad. It was an amazing
shake.

Re: Wobble
7 degrees is the factory specified Caster angle for a Wrangler. If you try
to keep 7 degrees with 4.5" of lift, you do get front driveshaft vibration
due to excessive pinion angle. But 5.5 to 6 degrees is entirely appropriate
and works well. It's the standard recommended Caster angle when you get to
4-5" of lift which won't cause any front driveshaft problems/vibrations but
it does give you enough Caster angle to give good steering qualities. My
own TJ is set to nearly six degrees and that worked very well with my 5.5"
of suspension lift. It's when you try to get too close to the factory 7
degree angle after installing a tall lift when the front pinion angle
becomes excessive for the front driveshaft and u-joint.

Re: Wobble
Right. However the last tech wouldn't go past 2.5deg. saying that the
DShaft has priority. I'm still not happy with the steering. Can I
ballpark the caster measurement? I know that the last alignment gave me
roughly 2.5 deg., so to get to 5.5 deg. I'll have to shorten the RE
upper control arms, but I'm not sure how far. I don't have the equipt.
to measure caster, obviously, but another $80 alignment isn't that
appealing either. Since I know where it is now (2.5), can I shorten each
arm, equally, to acheive a better caster angle and how many turns would
I attempt?

DShaft has priority. I'm still not happy with the steering. Can I
ballpark the caster measurement? I know that the last alignment gave me
roughly 2.5 deg., so to get to 5.5 deg. I'll have to shorten the RE
upper control arms, but I'm not sure how far. I don't have the equipt.
to measure caster, obviously, but another $80 alignment isn't that
appealing either. Since I know where it is now (2.5), can I shorten each
arm, equally, to acheive a better caster angle and how many turns would
I attempt?

Re: Wobble
Tommy, Caster angle isn't super critical but 2.5 degrees is clearly way
under what it needs. I would try four turns of your control arms
(lengthening the lower arms) and see how it feels. Just do the same number
of turns on each arm and it'll work fine. :)
