Introduction: Replacing the Power Chair Bearings- Permobile C300

Living a life of limited mobility is difficult, to do so in the country more so.  Living where a service call might take 2 weeks, more if parts are needed can make owning a power chair frustrating.  I have worked with Kelli's chairs since she was a student of mine.  This new chair is very nice but has issues about every four months with the rear pivot wheels.  By the time she knows they are failing and can make the service call sometimes it is too late.  Total bearing failure leads to damaged and missing parts and on one occasion being stranded in the road.  I am working with her to make bearing failure far less frequent and much less expensive.
