Re: A case of death wobble today
I wonder on the track bar.
Please fill me in on what you have so I can at least play 'devil's
advocate' with all the info I can get.... ;-)
A stock YJ with the soft flat leaf springs came with a track bar.
The CJ's before it with stiffer arched springs didn't come with, nor do
they need a track bar, nor do the lift kits call for one.
You have 35's and a Dana 60 in the front????
I would then think you might just have a lift of some sorts??? Does the
lift call for the track bar or is that something the shop added to make
up for a possible death wobble issue rather than re-make the spring
perches to get the caster right or to make up for a bad u-joint and axle
angle issue?
Do you have tall shackles per chance that the axle builders didn't know
about. That can crap out the caster big time.

Re: A case of death wobble today
Mike,
A few specs on my 92YJ Jeep:
- 35" tires
- custom Dynatrac built D60 in both front and back
- SUA with RE extreme-duty 4" lift springs
- Confer 1" lift shackles in front
- 1/2" MORE lift shackles in the back (levels it out nicely)
- 1.25" JKS body lift
- TJ flares
- Hi-steer arms on the knuckles, tie rod mounted on the bottom
- Adjustable JKS track bar.
Total of 5 3/4 - 6.25" of lift (most suspension). When the front-end was
built, they took all this info into consideration and I gave them several
measurements (running width of existing drive axle, spring pads distance,
etc, etc). Not to say the caster could still be off, though. This
front-end has about 3000 miles on it, and no problems at all with this
configuration until I encountered the DW the other day. At first
inspection, I found the track bar loose on the frame side mount. I had been
considering taking it off anyway, so at the time I temporarily removed it
just to see how the road handling would be.
I installed the front-end and track bar, springs, etc. No shop involved
here. I got the aftermarket track bar to replace the original and have been
using it for, oh, 6 years or so. Never a problem with it. Why a track bar?
Because the YJ came with one originally. The spring company nor the
Dynatrac recommended a track bar. If fact, Dynatrac suggested removing it.
More than one person has advised me that I don't need the track bar, but I
will be putting it back on anyway. Even though it may mask the real cause
of the DW, I still take comfort in it being there! It is aligned in perfect
angle with the drag link. I'll know this week if the caster is off and
needs a shim or two. My guess is that's got to be the real problem, but
we'll see.
I bought this old Jeep new in late '91 and she now has over 203,000 miles on
her and still runs great with original 4.0L and tranny.
Thanks again Mike. Hey, I didn't mean to come across as a wise-a** last
post to you. Some thought I sounded that way.

just to see how the road handling would be.
I installed the front-end and track bar, springs, etc. No shop involved
here. I got the aftermarket track bar to replace the original and have been
using it for, oh, 6 years or so. Never a problem with it. Why a track bar?
Because the YJ came with one originally. The spring company nor the
Dynatrac recommended a track bar. If fact, Dynatrac suggested removing it.
More than one person has advised me that I don't need the track bar, but I
will be putting it back on anyway. Even though it may mask the real cause
of the DW, I still take comfort in it being there! It is aligned in perfect
angle with the drag link. I'll know this week if the caster is off and
needs a shim or two. My guess is that's got to be the real problem, but
we'll see.
I bought this old Jeep new in late '91 and she now has over 203,000 miles on
her and still runs great with original 4.0L and tranny.
Thanks again Mike. Hey, I didn't mean to come across as a wise-a** last
post to you. Some thought I sounded that way.

A few specs on my 92YJ Jeep:
- 35" tires
- custom Dynatrac built D60 in both front and back
- SUA with RE extreme-duty 4" lift springs
- Confer 1" lift shackles in front
- 1/2" MORE lift shackles in the back (levels it out nicely)
- 1.25" JKS body lift
- TJ flares
- Hi-steer arms on the knuckles, tie rod mounted on the bottom
- Adjustable JKS track bar.
Total of 5 3/4 - 6.25" of lift (most suspension). When the front-end was
built, they took all this info into consideration and I gave them several
measurements (running width of existing drive axle, spring pads distance,
etc, etc). Not to say the caster could still be off, though. This
front-end has about 3000 miles on it, and no problems at all with this
configuration until I encountered the DW the other day. At first
inspection, I found the track bar loose on the frame side mount. I had been
considering taking it off anyway, so at the time I temporarily removed it
just to see how the road handling would be.

Re: A case of death wobble today
Ok, so you have a custom, built all to crap unit, eh....
I have one pretty easy check 'maybe' for you...
On a stock Jeep front end, the pinion face is straight up and down.
So the proper caster angle corresponds to a straight up and down pinion.
