BJ's no... at least not yet - I'm waiting for them to go bad so I can replace them. I don't feel like fronting 400 bucks just to replace something that ain't broke yet, lol. So when they start to crap out, I will replace them then. My Axles and driveshafts are fine. The lift is still within a comfortable angle of operation as to not stress out the xcase or cv joint too much - by the time they would have gone bad - I would have probably already popped in some aftermarket. What I won't be doing is stacking any spacers or anything - I know there are a lot of WK's moving in the direction - But I will wait to see how the WK handles that first before I step in that direction.
