a) Is there a ton of information in the bloody knuckle? Enough stuff to help me through my ring and pinion install? It's definitely worth it over the hundred it would cost to have it professionally installed. b) I took out my carrier, took out the pinion assembly bolts on the rear (6 of them) and now need it out. Do I just take a screwdriver and hammer and get it out like the ring gear from the carrier? The ring and pinion I bought has a new pinion assembly with it, so I don't plan on using the old one, but I may need it.
