alignment
 
Hey all. Safe trails to everyone. I recently had the alignment done on my Wrangler Sahara, 02. Was getting a little wobbly around the 50 mph mark. Everything seems good now, except for a very slight pull right. I was wondering if anybody had the factory recommended alignment numbers, i.e. toe, camber, and thrust angle for the front and rear tires (haha - thrust angle. That's funny. Yes, I'm a little demented. I do drive a jeep after all).

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.

Thanks for your replies. Was out of touch. Just got back to looking after the jeep.

Ok, so I took it back but the shaking returns. I can see the toe in needs adjusting and can see the clamp and adjustment nut. Gonna try to do it myself. If this keeps happening, does that mean something else is wrong? Any tips or procedural Know-how is appreciated.
