I have Joe's drops and cross members on both trucks, never had a problem, never broke a CV joint since the upgrade, and both of my Zus are locked in the front. Only con I can see to the 2" diff drop is it changes the angle of the front drive shaft to front diff. I have a torn prop shaft boot, but its been torn for a few years, no problems. The Trooper (non tod) uses a universal joint vice the stupid CV joint. I would rather change a prop shaft than a CV joint any day, plus the prop shaft can be found on any TOD model trooper/SLX, where as our CV joints seem to be "special".
