And that's why I never use the 3 point puller, only the one that uses all 5, or I pull the whole thing and use my press.
What Trader said - pull the key out of the keyway, line the hub up, mark for a new keyway, etc. The key is there ONLY to index the same hub back onto it's mating axle. The key has zero to do with strength. It's so you can service the thing by pulling the hub, replacing the seal(s), bearings, whatever, then put the hub back onto the axle and the key indexes it back to the exact same location to align it on the original splines (since the axle cut those splines into the hub anyway) That wimpy key is an index, it's not holding the hub from spinning. Anyone that thinks that tiny little key is holding back over 300 hp and as much torque should give back their engineering degree. |

If you still need axles and hubs, I have a set of what I think are AMC20 axles and hubs, used but matched, hot tanked media blasted (where appropriate) and painted. Pressed apart obviously, ready to install. 1977 Hornet wagon. I pulled them myself long ago. I'll never use them. There may be different lengths and all that, and you'll want to verify fitment; PM me if interested.

FYI, my 1960 AMC15 does not have keyways. There's a stamped mark across the threads, and on the hub. First time I'd seen that. Apropos to nothing.

(3 posts! sorry) for the record, I've long since given up on hub pullers. My axle service is always repair, eg. not performance upgrades etc so when I pull it's for bearings and brakes etc.
I take them to a machine shop for removal by a press. Of the last four axles two required extra effort, and one required heroic effort. As they get older they get stucker, or something. The difficult one took many interventions, heat, fluids, added a nut to spread force (and ended up squashing the threads a tiny bit, nonetheless), and on the second try, left in the big press overnight. I bring in the axle+hub+brake rattling assembly, have the shop press off hub, bearing, press on new bearing. It's a nice synergy of operations for the shop. Then home with clean parts for bearing packing and assembly. I'm over myself having to do everything at home, I don't have to own or maintain or equip a big tool I use once or twice a year, etc. YMMV. |

They may not work for his application if the brake sizes were different. They may, but they may not - because the hub was different to account for the different width of drums. Wrong hub, say a hub for the smaller brakes, will set the brake drum for the larger brakes up against the backing plate and it won't clear. For disk brakes, the difference will be where it sets the rotor in the caliper. It may move it in or out from where it was. There were indeed different hubs - the parts book explains. |

Thank you very much for the offer! I have a line on an axle shaft w/ hub that is from a '79 Spirit with an AMC 20, so that's a known quantity, but is more $$$ and effort than just doing a hub, so it's down on the list for now (but rising as the unavailability of hubs becomes apparent).

Check the pics I included in his other thread - the hub is considered part of the brakes, group 8. It's not part of the axle, etc. I showed a couple of pics of the possible combinations. More than just 1 or 2 for a 20 and 1 or 2 for a 15. |

I did! I assumed hub was part of the axle's group. Upsetting to my assumptions! lol |
