castor pinion angle

I have a 98 cherokee with a rubicon express 5.5 inch lift. If I'm going front dana 44 out of a wagoneer, what should the caster and pinion angle be at?

This is going to vary on quite a few things and how much work you want to do.
If you cut and turn the knuckles you can get everything dialed in where you want it. If you don't then you are going to have to make a compromise. IIRC there was 6 degrees of difference in my Waggy housing, ie pinion angle of 0 degree I had 6 degrees of caster.
I believe the 44 build up sticky by Crash says that 5 degrees of caster is a good number to shoot for.
