Hey all. I have a 2000 XJ lifted about 3.5 inches in front and 4 inches in the rear with adjustable LCAs and track bar from IRO. I recently replaced the unit bearings and had some odd vibrations at speed, so I took it to a free alignment check place and had it looked at. The ball joints feel solid with the jeep jacked up and pushing/pulling on the wheel and pressing up on it with a pipe. Tie rod ends and draglink/TRE are all new as well.
The report lists:
Camber driver's side: -1.52 degrees
Passenger's side: -0.47 degrees
Caster driver's side: 7.24 degrees
passenger's side: -0.47 degrees
Pinion angle is at 5.5 degrees (my measurement off front of the diff)
Toe: driver's side: 0.97 degrees
passenger's side: -0.90 degrees
total: 0.07 degrees (in spec, my measurement is 3/16 inch)
Rear thrust angle: -0.29 degrees
1: Is it ok that my caster has that much difference between sides? When I originally set the LCAs, I set caster off the tops of the ball joints at 7 degrees. When I measure now I get almost 10 degrees passenger and 7 degrees driver. That measurement isn't as precise as an alignment machine but shouldn't they be close? The pinion angle didn't change between initial setting and now.
2: What could cause the bad camber? A bent axle? Everything seems tight.
3: Is there any way to fix the thrust angle?
4: The rear pinion seal leaks when I have the drive shaft bolted in but stops when it is taken out. Is this simply a pinion angle adjustment or possibly related to the camber being out of spec or caster differences?
Thanks for your help!
