Pkmcgee Posted March 13, 2022 Report Share Posted March 13, 2022 I'm in the middle of a front disc brake conversion and when I disassembled the right front drum brakes, there was some scoring evident on the axle. My question to the group is this . . . Since the new hub rides on the bearings, does this scoring even matter. You can see in the second picture that the portion of the axle that both the inner and outer bearings ride on is free of scoring, so it seems like it should not matter. I'm actually not sure what caused the scoring on that part of the axle. The driver side axle had no issues whatsoever. Do you guys have any thoughts on whether I should replace the spindle or not. Thanks for any advice you can offer. Patrick Quote Link to comment Share on other sites More sharing options...
Jerry Roberts Posted March 13, 2022 Report Share Posted March 13, 2022 Don't worry about it . It doesn't matter . Left like that from the factory . Quote Link to comment Share on other sites More sharing options...
Pkmcgee Posted March 13, 2022 Author Report Share Posted March 13, 2022 Might have. I'm just using dumb logic that if the bearings do not seat on the scored part of the axle, it should not matter. But, maybe I'm missing something. Quote Link to comment Share on other sites More sharing options...

I’ve never seen one that didn’t look like that. Quote Link to comment Share on other sites More sharing options...
Pkmcgee Posted March 13, 2022 Author Report Share Posted March 13, 2022 Okay, then that's a relief. The driver side axle did not show any scoring, but if it is a common thing, I won't lose sleep over it. Thanks, guys. Quote Link to comment Share on other sites More sharing options...
DJ194950 Posted March 13, 2022 Report Share Posted March 13, 2022 One good machinist at the factory early in the week did one and the other a lazy machinist after a boozy lunch on Friday afternoon. No worries as to the rough machining as nothing rides on the area. DJ 2 1 Quote Link to comment Share on other sites More sharing options...
FarmerJon Posted March 13, 2022 Report Share Posted March 13, 2022 Even with modern cnc, rough areas like that can happen. Dull tools, aggressive cuts and high feed speeds help pad the bottom line, but make ugly parts. They are nicely finished where they matter. As a note, my '53 DeSoto spindles looks the exact same.

Sniper Posted March 13, 2022 Report Share Posted March 13, 2022 My P8 had spindles that looked like that. My P23 has nicely finished ones. Quote Link to comment Share on other sites More sharing options...
