Rear Wheel Failures

[DRAGONFRUITGSD]

Any one else have any rear wheel failures? I am on my second failure on my s10lx. It seems like water can get into the freehub and corrode the bearings. My first failure was last June at about 5500miles. My rear wheel was replaced and now i failed again after another 2k miles. My rear wheel makes an intermittent grinding noise and I will probably ride this one out while I build a wheel with a new hub. I purchased a hope pro 5 e-bike Hub to make a new/spare. It looks like there are some options to buy a replacement freehubs but mostly in Europe with high shipping costs.
