I haven't heard of many spider gears doing what mine did, and my axles previous owner was equally hard on the axle, so I chaulk it up to freak chance. A spool and a new set of 4.56's and I'm good to go. This axle is in a HEAVY ZJ, nice 4.6 stroker, ax15 with a great clutch that is still new and tends to act like an on/off switch, and 35's. I did this 'showing off' on pavement, with alot of traction.
Perfect time to install the new axle bearings i just happened to have laying around. And i was gonna lock it this winter anyway, I'm really only out the cost of the gears.
If your on a budget, you can pick this axle at a pull-a-part for about 125 with 410's and a limited slip
