Why the hell do these machines eat wheel bearings like they do??

I must say mine have been fine touch wood.... especially compared to the orange variety machine!! Make sure you buy good quality sealed bearings, and pack in plenty of grease, ensuring the seals are also intact and clean when inserting, should be OK really.

To be fair, there not the biggest of bearings, and, jet washing, as well as only having a single bearing on the drive side all takes it's toll.
But, on the up side, you'll e be an absolute dab hand at wheel bearings in no time
+, changing frequently means there's less chance of them seizing in there.
