How to Determine Correct Bearings and Seals for Pop-Up Camper

Expert Reply:

I can help you determine how to find the correct bearings and seals you need for your 1988 Coleman Columbia pop-up camper although there is no database which has all of the individual parts for each year, make and model of trailer.

So what you need to do is take apart your hub assembly and look at the bearings themselves; wipe away the grease and you should be able to see the part number stamped directly on them. If you are unable to find them, you need to use a digital caliper such as # 301-17068 and measure your spindle to the thousandths of an inch where the bearings ride. You can use the photo I've attached to see exactly where you need to measure.

I've also added a link to a help article on common bearing sizes, as well as a link to our available bearing kits.
