'93 ZJ Toe-In Specification

There was a TSB issued in September 1993 to revise the toe-in
specification for the '93 ZJ as shown in the factory service manual.
Unfortunately, the TSB only says to insert the new page in the manual,
but doesn't say what it was changed to. The manual shows the toe-in
on each side to be 0.12 to 0.22 degrees. Anyone know what the "new"
specification is?

Not a clue. All I remember is a TSB for caster angle to replace the ball
joint with an offset one.

Best suggestion I have is to contact your local Jeep dealer
and ask, one of the service mechanics should be able to easily
look it up.

It may have been related to Death Wobble. I had a local suspension shop
do the adjustments and had them set the toe-in to the lower end .12 The
upside is tire wear is more even, the downside is tracking on the highway
is a bit more "iffy". i.e. tends to wonder a bit. No DW though.

Thanks Doug. I took my Jeep in for alignment today, and just wanted
to be armed with the numbers. It was not a Jeep dealer.

I was having a problem with "loose" steering. That's why I took it in
in the first place. He took one look under the Jeep and said I was
about one mile from disaster. He had me look with him and he turned
the nut on one tie-bar end about a half-turn with his fingers and the
tie-bar fell off! The guy who put on the new tie-bar ends in 2002
apparently did not install a cotter pin. It took 2-1/2 years for the
nut to work itself loose. When I think about the times I was flying
down the freeway at 80mph and the tie-bar could have fallen off. I
was very, very lucky.

Ouch, doesn't bear thinking about.

Indeed!

I'm a great fan of safety wire. Alas most fittings don't use
it anymore since it's such a royal pain to use. Especially with
having to get the right hardware (bolts with wire holes).

true - haven't seen safety wire in a long time. I have a pet hate of people
reusing split-pins / cotter pins ; they are so cheap they are practically
fee ...

Did he forget the rest of carter-keys in the other tie rod ends,
too?

The shop I took it to today checked it out pretty well.

Agreed. Used safety wire a lot in aerospace manufacturing back in
another life.
