I broke two of them in the span of two years. Every time it broke it sheared the cross shafts for the spiders (Power Lok) which caused the spiders to break off teeth which ends up in the ring and pinion. Replaced the cross shafts, pinions, side gear and ring gear each time.

Didn't break while turning corners it actually "popped" right off the line. Usually went all the way down the track without problems but as soon as you turned off to the return road "snap, bang, clunk, pop..."
