Didn't have time to source a replacement part, so I fabbed one up. Pretty easy to do actually.
The PN4 has been disassembled, cleaned, sanitized, and the bearing fixed.
Major lint buildup under the power nozzle neck, and around the motor. (it couldn't breathe)
I always put a little piece of sound dampening under the motor to keeps things quiet.
It runs much better.
