Re: Difference between 55 & 56 rear end assemblies

What is the 56 senior rear axle, a Dana 53? I only have one experience with them and that's on my 56 Carib that had the TT. When I bought it at about 78,000 miles from the original owner who gave the car overall impeccable maintenance, the TT components of the carrier were very severely worn, pinion bearings shot, and as a result the ring and pinion useless. I replaced it with an NOS non-TT carrier and new ring and pinion sourced as I remember from Patrician Industries.
The TT part of the system aside, I'd much rather work on a Packard-made rear, far easier to service (no need for a case spreader, etc.). My experience limited as it is says the TT is not particularly robust. Both of my rear axles had the white (or yellowish) daub of paint on the ends indicating that they were the final generation of the axle upgrades. I don't hear anyone talking of axle breakage so I'd guess all the defective axles are long since out of circulation.
EDIT: I rather doubt lubrication was involved in the wear of my TT, there was a partial case of this stuff in the trunk when I bought the car. Unfortunately I was retired at the time and never had a chance to have this stuff analyzed to see what it contained.
