UCF Skid and front pinion angle Castor help

Finally got my extra original clearance skid plate on. 1/4" aluminum. It's the 2" skid NOT the 1" ultra. I got it all up and pretty damn pumed!

Anyway I must have a one in whatever exhaust setup cause it's all not fitting and muffler has no room. Hangers an bushings for them are pushed up an stretched already so. I may just have my exhaust guy cut up the middle length and maybe use a smaller muffler and move cat forward more but. Mainly muffler. Anyway

Rear pinion I set up. On top of a 3" kit it was pretty low. So w this move I had a lot to adjust. Now for the front I had minor change but deff looked low so, I turned my savvy arms 1 turn each on uppers and got it much more straight. Is that goin to kill my castor or anything to much? Should I go an try driving it a bit before deciding? I am using stock transmission Mount which was good room and is pretty much great. Got to Test more but main question is front pinion angle and castor effect. Prior my jeep was driving great, self centered steering, and was good aligned recently.

Usually, you adjust for the pinion angle and then cheat it a bit to help your caster. Since the front shaft is so long, you can get away with having the pinion angle a bit low to help out your caster. This is where HP axles come in handy.

I disconnected my tailpipe assembly and drove to an exhaust shop to have it fixed.

What he said above about the front pinion angle/caster. I got a lifetime alignment at Firestone and have brought it in several times. Get your pinion where you want it and go get your caster checked. Make adjustments and get it checked again.

When I went to Firestone I told them I would be in a few times in the next few weeks. He said OK. I did 4 alignment checks in the first 4 months. They give me a little attitude now. That's OK though. I don't want to take advantage of anyone and I got my money's worth! When I come in, I say you don't need to adjust anything, just check it.
Stop thinking and all your problems go away.
