Geometry question

[Red-dawn]

Hello and thank you in advance. I did search here for the answer but I did not find it. Sorry if I did not search correctly. 2021 JLUR with a Dynatrac endurosport 2 in lift and 35 in tires. The Jeep steering is not bad but not the same as when stock. I measured my caster the way I read to do it and on YouTube. At the pumpkin, I am at 92 degrees. At the bottom of the C on the driver side I am at -5. I measured at the pinion and it’s -2. Do these numbers sound off to you and if so, will I benefit from geometry correction brackets or anything else. I can re-measure a different way if I did it wrong or if I should try a different location.

the surface the jeep is parked on needs to be level or it will throw the numbers off. 92* at the diff would be 4* of caster if the jeep is level. That is probably about right with a 2” lift and stock arms. You want 6-6.5. Adjustable arms would be your best bet.

I did check where the Jeep is parked and it is level. so if I install adjustable arms they should be uppers and lowers and I should shoot for 88*?

You only need the uppers or lowers, being that the lowers are subjected to contacting trail obstacles, we went with lowers. 89° should be 7° of caster.

90* will be 6* of caster. Depending on how the gauge is facing on the diff you are looking for 89.5 or 90.5. Lowers will push the axel forward and get it back somewhat centered in the wheel well.

Thank you all for the responses!
