Jeep Guy

This post will be more in the line of a story, but there is a question at
the end. So today I spend some time with the beloved Jeep. It all started
with just wanting to finish the spare tire mount (it's trailer spindle with
some 2X2 steel tubing, another day). As I had the welder out I was just
looking around at things and noticed that the front axle spring perches were
broken away from the axle. A buddy of mine "welded" them about a year ago
or so. The welds were broken so I decided to re-weld them. After about two
hours of measuring the angles, checking the service manual, and measuring
again I welded the axle in place. It was almost exactly the same angle as
before (tipped 1/4 degree farther back is all) Nice solid welds, no
problems. And then I took it for a test drive. At about 35 I felt the
strange resonance and the Jeep began to sway back and forth. I haven't seen
this problem in the year since I did the SOA. I would have thought it would
have shown up right away. There were no other changes to the suspension.
I've read of few posts about Death Wobble, but I for the most part ignored
them as they didn't apply. If anyone has any words of wisdom, I am all
ears.
Thanks for listening to my rambling.

I'd say you got the angle wrong. Time for some caster shims.

I kind of was thinking that, but the previous welds are only about .010"
different from the current welds. This is about 1/4 of a degree. Any
suggestions as to which direction to try with the shims?

Your welds may have pulled the Camber out. I do it all the time, I
think if one weld is good why not run three beads, and shrink it every
time. Anyway, a new stabilizer shock will cover up all alignment
problems.

If you are wobbling then you need more caster. Try Bill's suggestion
regarding the stabilizer first.

I have a 97 Jeep and within the last several months my Jeep has developed a
wobble. It's most noticeable when I go around a curve and the road is bumpy.
It feels like the body of the Jeep is coming off. Any ideas? We've pulled the
tires off and can't see anything but we know we have a problem. Help!

I'm having the same problem on a 95 model at speeds 60 and above when I hit a
bump like where pavement and a bridge meets, where do I start to look?

Roy Jenson

Changing the stabilizer just masks the REAL problem. Usually it
is a combination of big tires that are somewhat out of balance,
something loose in the front end (look at tie rod ends, ball
joints, wheel bearings, and track bar fittings), bad front end
alignment and a stabilizer that has worn out trying to keep
things under control. Yuo hit a bump, the out of balance takes
over, the wheel precesses (wobbles), and the suspension pieces
are too loose to control it. UGLY.

Take it to an alignment shop that knows how to deal with 4wd
Jeeps and their solid axles. Have them get the alignment readings
and check for the various loose parts. Take it home and replace
whatever, bring it back and finish the alignment. My local shop
put mine on the rack, told me what parts to replace and sent me
on my way. Came back a few days later to finish the job, only got
charged for one trip. Nice of them!

You need to fix it ASAP. A bad case of death wobble can start at
60mph and won't stop until you get it under 10mph. The time in
between the two events can feel like an eternity. If you are in
traffic, it might be the last thing you will ever worry about.

Cheers.

Thanks, Earle
Death wobble certainly takes your mind off of traffic. Appreciate the
Information.
