Is there a "best" release bearing - 2005 3500 4x4 w/ g56. Is the NAPA, Sachs, National or xx brand best? Also I have made the decision to seperate the trans, take a look at clutch assembly and only replace release bearing if clutch is fine. I have had no indications of clutch issues just the bearing squeeling like a pig. I have the south bend SBCG56-OFEK with about 45k on it. thanks
