I tried rebuilding (two days at it), I can't do it with hand tools.
I used a grinder to cut the race that is pressed to the shaft.
When I reassembled it wouldn't turn freely.
I have a feeling that NAPA gave me the wrong bearings or I am doing something wrong.
Lots of work involved with rebuilding I think my cost for bearings was $70.
May try again sometime, but not soon!
