Smile pinion angle

Im working on putting some scout dana 44s in my cj3a. On the scout the pinion on the front axle came basiclly straight out. Im going soa so im wondering if i should rotate the pinion up a few degrees, or leave as is. Im also worried about axle wrap is there a good way to take care of this with giving up ground clearance.

the problem with changing the pinion angle is you end up with negative caster, and that's not acceptable. the only real way is to cut and reweld the ends of the axles to get the right caster.

here's a good article: Swapping a Scout II Dana 44 Front into a YJ

haha, no i forgot who gave me that. but ya, i would reset the pinion angle at the same time.

this is from that link talking about it, quote: While I was at it, Rob convinced me to angle this new perch so that the pinion pointed towards the xfer case output. This provided extra ground clearance under the pinion yoke and allowed me to use a CV shaft. Grinding this perch into the housing was surprisingly easy.

i think im gonna stick with u joints in my drive shaft not a cv shaft. i know there has to be a certain angle for proper operation, but im not sure what so i was kind of looking for a number of degrees to turn it up. We are going to mount the 44 on a mill to mill out the new perch and i made my own perchs. i will post up some pictures of my handy work when we are done.
