Hi Bill, If possible, I'd like a more detailed explanation of how to convert to "Green"-type bearings on the older style rear ends, as those found in 1955 thru 1964 Chryslers. I was not aware that this modification could be made. Have you personally done this to one of those rears ? Yes, I know this can be done on the '65 and younger Mopars.. Also curious about the removal of the thrust pin, in SureGrip rears. What does one do if it's a non-SureGrip? There is no thrust pin.. On this topic, I agree with John Nowasacki - the original design was good for 30+ years or 150,000 + miles. Bearing failure usually occured when the inner seal got weak and rear end fluid washed out the grease on the bearing. This is easily remedied with all new seals, and a new bearing - and should be good for another few decades. As to what caused Pete Fitch's bearing failure in his "G" - no idea, but perhaps a defective bearing, or improper installation.
