How to Determine the Correct Replacement Wheel Bearings for a 1990 Coleman Pop Up Camper

Expert Reply:

Trailer wheel bearings are specific to the spindle that is installed on the axle that is on your 1990 Coleman Pop Up. The easiest way to determine the correct replacement bearings for your trailer is to remove the hub and find the part numbers that will be stamped on the inner and outer bearings.

To remove the hub you will need to safely support the trailer, remove the wheel and tire, remove the grease cap, remove the cotter pin and washer that secures the spindle nut, remove the spindle nut, and then you will be able to remove the hub from your trailer. I have attached a video showing how to remove the bearings from your hub.

If your bearings are damaged or you are not able to find the part numbers on the bearings, then you can take a few measurements on the spindle. We would need to know the inner diameters of the inner and outer bearing and the grease seal. These measurements will need to be as precise as possible, so I recommend using a dial or digital caliper.

I have included a photo that shows where you can find the bearing part numbers on the bearings and where to measure on the spindle. You can then choose the correct bearings based on the part numbers or by the inner diameters.
