I have come across two of these lately. Carrier bearing race 3.025 with came in a kit from Quick Performance. If you have your carrier installed into the housing but having trouble turning the adjusters this might be your problem. If the carrier brg race number is LM104912 it is wrong, should be LM104911. LM104912 is .0015 larger in diameter and if you use it, you will not be able to to make carrier brg adjustment. These bearing were part of the Yukon bolt through aluminum housing with 3.025 diameter brgs.
