I don't think Jeff meant he was going to put a squealer back in...but
I've fixed up four or five blower motors and all worked for years
with no problems.  All had little wear on brushes and commutators but
were seized or almost.  I would be very hesitant to re-use a motor
whose bearings were loose enough to chatter in this application
(though I've kept sanders, saws, computer fans and such going for
years with frequent oiling - each use in the case of power tools).

Repair involved removing the motor from the housing, cleanup with
multiple changes of Marvel Mystery Oil and bench running, oiling of
bearings and bearing felts with machine oil, bench running for 2-3
days continuous and then replacement into the housing.

R&R in the housing is thoughtful work because you can't exert much
pressure between shaft and motor case without wrecking a bearing or
moving the armature on the shaft  (and if you drop the motor when it
falls out of the housing as you tap the shaft off the blower wheel it
may injure itself).

Yrs,
