> something stuck in the bearings/bushings This is tracks with my experience. I used to work for a mid-sized US grocery chain in the Midwest (Farmer Jack if anyone remembers those, gone now) and I once got reprimanded for cleaning the cart wheels. I didn't even have to take the wheels apart most of the time, just get in there with some WD-40 or pop out the small bits of concrete or rock with a screwdriver. Apparently that was a waste of time in my manager's eyes since "the carts were always broken anyway" and I was supposed to be unloading stock.
