will LCA's increase wear of driveshaft joints?
I just went to the dealer the other day (to have another warranty claim denied
and told him about my idea to replace the lower control arms with adjustable ones to improve caster. He told me not to do this because the angle of the drive shaft joint with the front diff will change and increase wear of the joint among other things.
Is this true to a signifcant extent? Because I "see" a lot of LCA's around here on this forum. I have 2.5/3" OME lift kit.
Thanks!

HI
Well, actually is oposit.
By lifting the jeep u have changed the angel already. If u move u axel back to the factory position u will change the angel of course again, but it will be less stressed angel then without that.
I made the same choice, OME and JKS adjastable lower, upper, front, rear, and trackbars.
Upcomming changes are Terraflex speedbumps.

Many owners with lifted JKs use adjustable CAs to dial in caster lost from their suspension lift.
The potential problem is, it's entirely possible to dial in more caster than you really need in the pursuit of straight line stability. This leads to more drive line vibration and shortened U-joint life.
Why? Because caster and pinion angle are inversely related.
The truth lay somewhere in the middle. Close to zero degree pinion angle + someplace near factory caster spec (4.5 degrees) if you can achieve such balance.
