Not enough information- - - -is the pin worn, or is the hole egg shaped? It would be possible for a really good machinist to line ream the carrier and press sleeves into it, but it would be cheaper to just buy another carrier. Back when automatic transmission "shift kits" were popular with people who didn't know any better, I saw several carriers with the pin hole worn oval by 1/8" or more. There was a good reason for the wear, which isn't really important to this thread, but it was a direct result of altering the transmission shift strategy.
