The only ends you need to mark are where the two halves meet. Those have to go back together the same way after you replace the carrier. I had our Napa store do my carrier. I bought the u joints and carrier there and the labor was minimal. He also checked balance and while it was in the lathe he hit it with emery cloth to knock all the nasty scaly rust off. I'm thinking it was like $25 total.
