Matt Ive had no problems with my diffs and I have run it quite a bit. I think its like nitroexpress said, if they werent assembled properly you are going to have problems. I also think a lot of blown diffs happen with upgraded engines. The K4.6HO is a good engine but there are must more potent mills on there. I think with a loose diff and a powerful engine is where most of the problems occur. Driving style has a lot to do with it too. Doing 180's on high traction surfaces will kill your diffs fast.

supertib what is RRP upgrades?
