[QUOTE="TheKodiak, post: 428442, member: 19430"] First off, pardon my terminology if it’s incorrect. Still not entirely sure about everything lol. What’s the difference between caster angle and pinion angle? I just installed an Adams 1310 front driveshaft and was seeing that they wanted the pinion angle adjusted according to the image I attached below. The lift kit I had installed a few years ago did not come with adjustable control arms just fixed control arms so I was considering purchasing a set of adjustable UCAs, but before I do so I had a couple of questions. 1. Will installing adjustable UCA’s allow me to adjust pinion angle? 2. Do I need to have the axle at full droop to install the UCAs or can I just remove the old ones without lifting the Jeep and install the new ones adjusting the pinion angle by placing a jack underneath the pinion? I haven’t measured the current pinion angle or caster angle or anything like that yet because I don’t know how to. Can someone please provide a diagram or images on how to do so? THANKS!!![ATTACH type="full"]116342[/ATTACH][ATTACH type="full"]116343[/ATTACH] [/QUOTE]
