Drive shaft angle difference on two WJs

I've got two WJs (01 Limited 4.7 and 03 Overland 4.7). The 03 Overland has a much steeper drive shaft angle than the 01 Limited (15 degrees on the Overland vs 5 degrees on the limited. The primary cause seems to be that the 03 Overland's transfer case seems to be tucked up higher with additional skid plate apparatus in the area. Both are used with unknown history.



I'm currently installing a 3" IRO lift with adjustable Core 4x4 control arms and this extreme DS angle is causing me fits getting caster and pinion sorted out. Currently adjustments have at 3 degrees caster, 5 degrees pinion and 15 degrees drive shaft. 10 degrees difference in pinion and drive shaft doesn't sound good.


Any ideas? Has this thing had a previous tummy tuck causing the steeper DS angle?

I believe the Overland has a factory lift which may be causing the angle variation you mentioned. If you are installing a lift with adjustable arms, the caster/pinion angles can be tweaked to your liking. Easiest thing to do is install the lift + control arms and take it to a reputable place who knows how to perform an alignment on a lifted Jeep.

I agree. I believe the overland has the “Up country” suspension group. My Laredo has the up country suspension as well.
You do have to have it aligned after any type of lift.
