The Stovebolt Site Forums The Parking Lot Big Bolts 1968 C60 Rear Spindle Repair ??

Even though I also suggested chasing the threads, I changed my mind after it was pointed out that a close look at the bearing area of the spindle shows someone already used a center punch on it to expand it to tighten the fit of a make a replacement bearing after the previous one spun on the spindle. There is no good way to make another bearing fit properly any more.

Clean up the threads and put a new bearing on if you want but do not be surprised when it fails in short order because it cannot be adjusted correctly. Likely the reason why the hub is apart now.
