A Possible T Purchase and a Rear End Question

[rotorwrench]

From what I've read about the rear axle thrust washers is that Ford always used the babbitt washers with the steels. Since the trust washer is what limits axle movement for the most part, a person can jack one wheel at a time and see now much end play there is between the two. The left one is the first on the list since it is usually the one that controls the ring gear location. Too much gear noise is another indication since any looseness in there will start to affect the ring and pinion as well. Chunks of babbitt in the differential oil would be another indication. The model Ts always used the Hyatt spiral wound flat roller bearings for most load bearing journals so this is why they needed thrust bearings. The Timken tapered rollers in the model A cars took up all the thrust loads.

This is a good link but it's a later 26/27 one with the rear hub brakes:
