Thanks for the cautionary information about the trans. I will definitely take it out and have a look inside and for cracks in the tailshaft housing. My sprag is the one referred to as the "Ultimate Sprag" and includes more rollers as was mentioned in the write-up. Hopefully it held.

Back to the diff, I've seen write-ups that say to use a billet cap on the driver's side bearing. The price seems kind of high at $100, but if it gives any insurance against future failure, seems like it would be worth it
