I have a 2000 xj with 6 inch pricejacker. I just put some heavy duty custom LCA's on and i want to check the caster. I have searched and searched and I found the one formula numerous times, however it appears this formula is only for xj's up to 99. The low pinion dana 30 requires a different formula to figure out the caster, and I can not find it. If anybody knows this, please let me know. Also, I wanted to make sure when using the protractor I place it on the cover on the flat part inbetween the bolts, correct. Thanks.
