What Would You Do?
My 12 bolt 3.73 rear end out of a 1970 pinion bearing needs replacement. The gears are all in great shape with no visible wear. Would you guys replace everything or just the needed bearing?
I know the easy answer is to find another rear end but then I would not know what I was getting.

Re: What Would You Do?
I would check bearings for pitting and heat discoloration (scalding) and replace the seals if they are factory. Other than that why replace what aint broke

Re: What Would You Do?
I was thinking the same thing guys. Thanks for the reinforcement. The only thing holding me back is a slight desire to run 3.42 gears instead of 3.73, but hey I can live with it. Probably gonna make a trip to visit my uncle as he has been a GM mechanic since the last year of these beauties. That way I can have it done right but also learn to do it myself.
