Hi all! I'm helping my dad switch from a 4.11 to a 3.9 rear end in his '53 100. He also is swapping to to a different pair of axles, as a shop once told him his current axle's splines are worn (We'll see when we pull them out).
Questions: anything to watch out for? It looks fairly simple - he has the entire pumpkin, which he's going to take to a differential shop to get cleaned and inspected prior to installation. Hopefully, it's a temporary install until the next run of Lempert 3.54 gearsets.
Also - the used axles he acquired are slightly different from eachother. One has a geometric (hexagonal?) shaped flange (at the brake drum end), the other is circular. I'll do a more detailed examination when I can, but the difference makes me suspicious. He got the parts essentially free,, from a friendly club member.
Thanks in advance for your help!
