Re: Lift kit and front drive line angle
 
Dan,

I've had this kit on my '94YJ, although I have a D44 in front, D60 rear and
an Atlas II. I have CVs front & rear at the t-case. If you're retaining the
stock YJ D30 in front you may not have any driveline issues, however you'll
definitiely have caster problems from the kits 5" shackles (1" longer than
stock).

To correct my front caster I needed an additional 2 degrees. (The kit came
with four crap Pro Comp 2 1/2 degree aluminum shims which I tossed.) I had
the rear spring pads cut loose and rewelded with the pinion centered to the
T-case. In front I added steel shims from Poison Spyder Customs. They've
been on there two years and have held up fine.

FWIW, if you don't dial in the front caster it will be all over the road.

Re: Lift kit and front drive line angle
 
Yes, the shims keep the front wheel alignment correct. The YJ already
has a CV or double cardan joint on the driveshaft, so only the rear
needs one.
