For stock size tires, 7 (+/- 1) degrees of caster angle is the factory spec. For bigger tires, a slightly reduced caster angle is desirable. For example, 5-6 degrees of caster angle is about right for 33" tires. But without aftermarket adjustable length control arms or aftermarket cam bolts, your TJ's caster angle is not adjustable.
For toe-in, that is .15 degrees, +/- .15 degrees.
Thrust angle is 0 degrees, +/- .15 degrees. Also non-adjustable without aftermarket adjustable length control arms.
Camber angle is .25 degrees, acceptable is +/- .63. This is not adjustable without installing aftermarket or Jeep adjustable ball joints.
For a stock newer Jeep like yours, only the toe-in is adjustable and that is such an easy adjustment that you can do that at home with nothing more than a tape measure, pliers, and a wrench. If you're interested in doing that yourself, and it truly is easy to produce accurate results, we can provide you details on how to do that.
