we were unable to find a non cad unit local with a 4.90 for a good price so we had to pickup a cad diff BUT the sport cad axle has the actuator on top of the axle into the diff vers the montero cad set which has it on the rear, this difference makes for cleanance issues so we had to make the diff into a non cad diff with help from the porta band and a welder. <img src="/forums/images/graemlins/kewl.gif" alt="" /> so front end is pretty much back together now passenger side brake caliper has some issue with the threads kevin is gonna give you a call.
