How to Pick Out Bearings for a Trailer

Question:

I have a tent camper that has one side in bad need of repair. I have pictures attached of the area in question, and the identification sticker on the side. I dont have the tools to take the wheel off and see what size the bearings are. I hope you can tell me by looking up the model or VIN number on the sticker. Its a flagstaff by forest river pop up camper. Also I need to know how to make sure it doesnt happen again. What grease do I need, etc. The other side looks fine but Im sure ill need to grease that too as I havent since Ive owned it, and its been probably 1000 miles traveled since then. Couldnt say when they were greased before then. Thanks.

I really wish there was a way to determine what bearings a trailer needed without actually pulling the wheel off and checking, but there isn't. The only two solution I have for you would be to remove the hubs and get the numbers that are stamped on the bearing or for you to remove the hubs and use a digital or dial caliper to measure where the bearings and seal ride (see pic).

With that info I can help you figure out what you need.

The best grease to use in a hub assembly is the "red" grease like part # L11390. This grease is the most heavy duty and would work well for you.
