front and rear pinion angles

OK heres the deal, I'm installing scoutII 44s SOA in a cj 7. I know it's not advised but i plan to run a standard driveshaft. Right now there is no engine, trans, or x-fer case...just axles mocked to the bare frame. While I'm thinking in this direction and everything is easy to get to I would like to (temporarily) set the pinion angles and caster as close as possible knowing when the jeep is complete there may be some tweaking needed. Taking my application into account, is anyone willing to share their pinion angle, for mock-up purposes only?

You can't accurately set pinion angles with a bare frame; as the springs compress, the angles will change.

And you can't set the pinion angle and the caster angle - it's one or the other. The Scout axles have zero caster when the pinion angle is correct. You have to cut the eyes loose and rotate them.

EVERYTHING's easy for the guy who doesn't have to do it.

I'm with Jim -- there's really no point in doing it now. The angles depend on what type of skid plate you run, the arch that may (or may not) be in your springs, the weight of the rig as it compresses the springs, etc.

I'd just tack the perches on now, anwhere close (point it to the middle of the frame), and build the rest of the rig up. When you're closer to the end of the build, do it once.

Good luck
Pete

Ditto x 3.

And I wouldn't even tack the perches on....just get the u-bolts tight and leave it like that until you have everything together.....just don't drive it.

When I did my SOA, I actually took mine to the alignment shop to let the guy do the front....then I welded the perches. As it is, I have to do my rear perches again after doing the SBC swap...had to shorten the ds by 3" and that threw the angle off a little...
