i think the angle from my front ds might be off by a little, is there any way to adjust the driveline angle without getting adjustable control arms or getting a HP axle? i know you can shim the rear but i don't think it works in the front with coils..

 

this shows you how to adjust caster with homade shims

X2 for the alignment site, but what makes you think the angle is off? The fix all depends on how much lift you have and what the symptoms are. Might be as simple as a Tcase drop or control arm shims, or you may need to go with adjustable control arms. All depends on how much lift you have and how much YOUR xj was affected by it (they all seem to react differently).
