How to Pick Out Replacement Bearings/Races for a Wesco Boat Trailer


I have a 2005 dual axle Wesco trailer for my 21 foot boat. How can I figure out which bearings / races I need?


Helpful Expert Reply:

There are two ways to determine what would be the correct bearings/races you would need for a trailer hub.

Once way is to remove the hub and get the numbers stamped on the bearings/races/seal.

The other is to pull the hub and then using a micrometer get the dimensions off of the spindle and hub bore so that you can determine what would work based on that. See the picture I attached to see what needs to get measured and what the numbers should look like.
