As SWMBOs ability to walk is worsening, I've tried to use the advantage of time, to snap up some bargains for mobility.
Have currently amassed 3 portable "Aqua soothe" scooters, and a Roma Medical UL7 "Vienna" electric wheelchair.
The Scooter is a godsend (hence having more than one - a failure would be problematic). Currently, we have "good" on, which whizzes along quietly, with plenty of power.
Which leaves the 2 "spares" which are fully functional. However, they both make a "growling" noise when going along.
As does the powerchair.
Has anyone ever risked opening the sealed motor/gear assembly ? If so, what did you find ? (Hopefully not nylon gears). I note the only spares available seem to be brushes - however I doubt they'd cause the noise I'm hearing.
The powerchair needs new back tyres at £65 a pop (each), so I'm trying to avoid spending money if it'll be a waste.
