Working on a 66 front end. Has original hubs (assuming) which have been separated from the rotors - for how long I have no idea. At some point they had been painted black which I glass beaded off. The hub surface is clean and flat. Threaded rivet holes in hub and attached new rotors with flat head bolts after countersinking so bolt heads are sub flush to the face of the rotor.
Checking drivers side, runout is 0.002 max. Pass side it is coming in at 0.015" max. I swapped rotors between hubs and got the same results so the issue is in the hub - or spindle? I have not tried swapping hubs between spindles - yet. 0.015" seems excessive to me, could it be the spindle or the bearing races in the hub?
Best method to rectify? Turn on a brake lathe? I have access to one maybe just kiss the rotor to clean it up, but if there is something wrong with the hub bearings or the spindle itself, that would just be masking a different problem?
Suggestions welcome
Thanks,
Tom
