Ray, your rear hex being stripped could be the problem. But despite your being anal about the slipper, I still feel like this is where the problem is. I was blowing rear diffs like mad in my E-LST2 on 6s, and finally went with the HD diff and haven't had any problems since. It's not normal to strip diffs as fast as you do.

You may want to take a look at your rear wheel bearings. I had one blow and didn't notice. Also, advice that YOU gave me.... Sometimes it's hard to see a broken pinion tooth. In my case. My teeth weren't broke, but 3 of them had flattened a bit, and weren't meshing. Took me three tear downs to notice that! Replaced the pinion and all is well.

How much does your truck weigh fully loaded? I'm starting to wonder if it's just too heavy. But my money is on the slipper. I had mine where I thought it should be, and it wasn't enuff. So put it to where it should be, then go another 1/2 turn out and try that!

And like you, after spending so much time with my LST then switching to my ERBE...it was a very nice surprise. The ERBE is a fierce serpent, where as the LST is a bear!
