Where to get Replacement Wheel Bearings -Old Camper

Look real close at edge of bearing. Most times there is a name and number. If can't find that, take the races to a trailer parts/repair shop. Note; if you don't tell the bearing it is going on a RV, it will never know. Much more likely to get what you need from a shop that does not fix toilets and stoves. You are looking for trailer parts, not RV parts.
