This wheel hub does not exist as a spare part. You need to buy the total drive train.
So I revers engeneered it…

Water gets past the seal and makes the aluminium hub to rot. Ours was broken of as well… Not only that the bearing in the planatery gearbox starts to rust.
I printed on in Carbon fiber reinforced PA and one in PETG. I will be going for PETG even if it flexes more.

I would highly recommend to change the bearing at the same time. thy cost 10Eur for 10 on amazon. 698ZZ is the one you need (8x19x6)
Noth that you then need to dissablbe the gerabox some as well. Not that hard if you got this far taking the mover apart.
