Most likely. Dr Diff has the shafts for $50 a pair, so it must not be that uncommon of a problem.

I am now trying to decide whether to repair the Sure Grip or to swap in a spool. And whether or not to replace the ring and pinion along with the bearings. I have never ran a spool before, so I am not sure if I would like it or not. And I only put 1,000 to 1,500 miles a year on the car. So I doubt I would wear the bearings out even if they have had some trash ran through them. They are smooth now and look good. And I won't know until I re-set the gears and run them, just how quiet they might be. As long as I can hear the radio and talk at road speed, then I would be happy. But, of course, I won't know that unless I run them.

I would welcome opinions and experiences on running a spool on the street.

Decisions, decisions.
