Well my 2-speed motor starting making noises this week. The pump its self is a Sta-rite Duraglas PEA5D-180L/P2R5D-181L (Impeller C105-92PS Diffuser C1-216P) (Frankensteined to a 2-speed) Ordered a new shaft seal and bearings for my AO Smith SQL1072R. Motor was installed in summer of 2013.

The shaft seal was $5 for a PS200 and the bearings 6203-2RS (ABEC3) were $6 for both ends.
Hopefully the motor will come apart without too many issues.
I'll try to take some pictures and post the results here. In case it takes longer than a day I've got a 3/4 single speed standing by.
