Re: Best place to buy bearings...
ANY auto parts store will have the bearings you need, contrary to popular belief, auto parts stores have almost ALL the basic trailer bearings, races and seals, IN STOCK, just make sure you get a parts man who knows what he's doing and not scared to open a paper catalog to find them. Because if the man doesn't know what he's doing, he'll tell you he doesn't have them in stock while the parts you need sit on the shelf behind the counter 20 feet from him.
what i've found is About 90% of trailers use only about 10 different part numbers of bearings and seals which everyone keeps in stock!
