You haven't been around lifted four wheel drives much have you? That's exactly the reason for the 6" lift. Tie rod angles and ball joints are easily addressed, this is not rocket science. Differential angles are not adversely affected by this lift.

 

I think he was referring to the angle on the ujoints which would be affected. Every action has a reaction if you can't afford to drive a lifted truck then lower it back down. For a 2" lift your 100million times better with a body lift, you might not have that little extra ground clearance but you can use your skinny pedal more and not worry about toasting your axles. I'm going SFA soon to get rid of the lift choices for our trucks.

 

I have a 2000 ZR2 and have a leak where the cv joint meets diff (seal) and I believe my cv joint has gone bad on the same side. I see grease coming out of both boots too. Would you reccommend an entire axle swap? If so, what's a good source for rebuilt half shafts? Can't seem to find one for ZR2's. Thanks!
