Hi.
Ok, I have a 4.5" lift on my xj.
I was starting to get death wobble, so I got some longer LCAs and put those bad boys on. totally cured the DW, but I soon noticed a low speed dependant vibration. Suspecting a bad pinion angle, I removed the front drive shaft and viola! It went away. So, I put the shaft back on and sure enough it returned.
Sooooo
I picked up some adjustable UCAs to push the top of the axle forward, raising the pinion. The XJ is at the shop right now and they called wnated to make sure that I wanted to add negative caster to the ball joints.
I walked down there (a block from my office) and went over this whole thing with them.
So, in theory, with the longer lowers, adjustable uppers and lift, I should be able to have the caster and pinion correct by using the adjustables...correct?
I think the shop and I are all on the right page, but I just want to make sure.
Am I missing anything? Any advice? Any thing I should be aware of?
