Had three wheel bearings fail within the first year from New, suplier said I should wash the bearings out more even though I had been , took the trailer to a trailer specialist and found the trailer was under rated for the boat and equipment fitted and it was the brakes coming on prematurely that fried the bearings, pointed that out to the supplier and they swaped out the trailer for a new higher rated trailer without so much as as murmer.
