Plas62 was the poster that had broken both rear axles. One side , then later on the other. I haven't seen him here in a while. Either the axles he had were not up to par or possibly over stressed the axles. I seem to remember he got a lot done with that little rig. Also much of the work done while in 2 wheel drive. May or may not have helped in 4WD if he was working the rear wheels. He felt strongly that the differential lock wasn't an issue and in fact made a lock out so that it couldn't be used by accident after # 1 axle had broken.
