I finally got around to removing the pinion gear from my Cuda with the Dana 60, it had broken the rear pinion bearing cage at the local drag race last September when i put it in neutral from low gear and heard a weird noise and the car stop with a little jolt, maybe the rear tire turn less than a 1/16 of wheel rotation and stopped. It was locked up, so I ended up having to take the rear end apart and remove the spool and ring gear to load it in the trailer with the winch . The rear pinion bearing cage got torn up badly after the pinion nut came loose and released the preload on the pinion bearings allowing the pinion shaft to slide backwards into the ring gear evidently when I was stopping in the tech inspection lane before racing.is what I found today I dodge a BIG bullet on this I can't imagine how bad this could had got if it had failed after letting off at 150+ MPH i had driven it around on the pits to warm up the trans, engine and rear end lubes before making a pass and going to tech when it locked up THANKS be to GOD

So Cab you think the cage came apart then the rollers bound up the pinion ? I have never seen that in 35 years of working on drivelines but as we all know anything can happen in a drag car. Gus
