Pick up a issue of FOURWHEELER magazine and read the repeated articles on project Red Sled's CV shaft problem, its a common problem in these trucks, I had a friend spit a CV out just hooking bumper to bumper in wet grass with a 6.5 in a 96 model 2500 chevy, .....The Red Sled's front diff lasted about 30 yards on the trail before it split in half cause the upgraded shafts wouldnt break like the weak stock ones, and call EMS offroad and ask them they arent offering the free spin kit for the IFS chevys, because if they sell upgraded CV's (cost prohibitive is another reason) they know it will bust the differential if taken offroad......why do you think the diff isnt failing.....because the CV is the weak point and it fails before the diff does.......its like anything you build, you upgrade the tranny and the t-case breaks, you upgrade the t-case, then a driveshaft goes, bigger driveshafts now and your next in line is the diff, but the diff is stronger than the CV's, so they will fail next instead of the diff, BUT if you make the CV's stronger than the diff it moves your failure point back to the diff......and you get a diff thats split in half......
