My eye was right on with the rear pinion angle

Not as close on the front

But I checked and this number is the same as the pinion angle

And this number is the same as on top of the knuckle and a lot easier to get to

The only thing I don’t like is I had the axle centered on the bump stops before I had to shorten the upper arms, now it is not centered anymore

Do you have adjustable front LCAs? If so, you can lengthen both uppers and lowers to push he axle forward a bit while maintaining your pinion and caster angles.

My front uppers have 1”x14 threaded Johnny Joints that are only 10 threads in so probably 3/4 of an inch. I hate to do less, but if my caster with the unlimited housing should still be 4* like stock I will shorten the lowers a bit. If it is supposed to be 6* I’ll leave it where it is

Do you have all eight arms? I followed this on the fronts and was pretty dang close. 20201227_210455.jpg

Are you looking at the bump stop pads at full bump or ride height? Since the axle is traveling in an arc it may move forward enough at bump to align with the stops.

Yes they are tilted back and not in line exactly at ride height. I jacked the driver front tire as much as you can with the spring in. The bump stop hits I’d say the back 2/3 and does not get into the spring so I’ll probably call that good since I’d need new upper control arms to push the axle forward. It’s at 6* caster
