A jet of dry, compressed air directed at the bearings from underneath
while spinning the wheels seems to work well for me; most of the time
dust seems to be the problem.
Pasco recommends dusting, followed by application of silicone oil:

If you use something with solvents, take care not to get any on the
plastic wheels, it will attack them.
Pasco does sell spare wheels/axles:
