1940 pinion seal replacement

Recommended Posts

Anyone have experience with this task?  The shop manual indicates special tools are needed and that the pin used in the propellor shaft to pinion shaft connection will need to be replaced.

Hi Ken,

I recall doing work on a '39-41 GM rear end in the mid 50's, can't remember exactly why but I do recall that it was not an easy job. Getting the axles out of the housing required removing a block between the axle ends, once this block was removed the axle (s) could be pushed in which allowed the removal of a C clip, then the axle could be removed. The re-assembly required a dial indicator set up on the axle housing to get the proper alignment, back lash, of the gears, etc.
