Expert Reply:

I would be happy to help you determine the correct replacement hub with the 5 on 4-1/2" bolt pattern for your 1971 Norris Camper, but we do not have a breakdown of the specific components your trailer uses so you will need to take a few meaurements.

First you will need to determine your bearing combination. To do this you will need to remove one of your hubs and look for the bearing numbers stamped in the face of the inner and outer bearings as shown in the picture of the # L44649.

If the bearings are worn to the point that the bearing numbers are unreadable you will need to use digital calipers like # PTW80157 to precisely measure you spindle according to the diagram.

Next you will need to measure your spindle where the grease seal goes to confirm the correct grease seal.

If you can follow up with this information I would be happy to go over the available hubs for your trailer.
