Caster and Toe In are the only adjustments available.

If one could draw an imaginary line through the center of the upper and
lower ball joints, and include the center of the spindle, that line would be
known as the Caster Angle. Actually, the angle at which the line hit the
ground is the Caster Angle. Zero degrees of angle is a line that hits the
ground at a perfect perpendicular (90°) angle. If the line were tilted
forward or backward, the degree of variance would be measured with + or -
signs, and the number of degrees off of 90. The Caster Angle should lean
towards the back, the spec is different for all cars, but generally the
number is around 7°. Some are higher, some are lower. Your CJ will need this
number to be in the range of about 4 to 6 degrees. If less than 4, and a
small obstruction is encountered while driving, the tires will search for
the straight ahead position. Add to this searching, the high probability
that you have stuff like worn tie rods and ball joints, and the searching
can becoome very dramatic. We call this Death Wobble. The only recovery is
to reduce your speed until it goes away.

The Caster Angle is pretty well set in your CJ because the axles have a flat
flange welded on them that the springs are bolted to. I would be looking at
the ubolts that hold the axle to the springs, then I would be checking the
ball joints and tie rod ends. These are parts that can be worn on an old
CJ7, but should not be worn on a TJ yet. The TJ is more suceptable to Death
Wobble from poor caster angle than a CJ or.


Toe In is set by adjusting the turnbuckles on the drag link (steering
linkage). Toe In or Toe Out are the same thing in opposite directions. the
Toe In will be the cause of pulling to the side, or steering wheel that is
not centered properly, that sort of thing.
