funny you mention that...
The pinion angle is at 7 degrees where it sits. The axle is a custom cater is negative 2 degrees. been thinking about droppng the arms to get about 2 degrees of caster. but the pinion angle would suck at 3, so i will be rotating the c's eventually.
The angle on the driveshaft at the transfer case is rather extreme, and I will be bolting up a cv style shaft to correct that.
