Ongoing problem with Hybrid output shafts...

[Arct1k]

I spoke to mike after number 1 went down and showed Jamie and Mike the broken one at the bash...

I took the diff apart last night to replace the sheared one with my last spare but the second one is twisted to badly it isn't worth rebuilding the diff.

I have emailed mike tonight and sent him the pics...

In cases like this, one tends to focus on the broken pieces as the "source" of the problem. However, maybe the real issue lies somewhere else in your drivetrain. Is it possible one of your shafts is binding up in a certain suspension position? If so, I would think your slipper would give before putting out enough power to shear these. One yes, three - no way. Just thinking out loud here...
I guess it comes down to one of two things. Either a string of defective parts, or you have something occuring that creates great opposing forces at that spot.
Has it been in the same spot every time? Have you noticed when it occurs?
