How To Determine Correct Replacement Bearing Kit


I need help on a size of bearing kit for a trailer


Expert Reply:

To find the correct size replacement bearings for your spindle on your trailer there are couple different ways to measure. You first would need to remove the hubs from the spindle. You can remove the existing bearings and check for a number stamped on the side of them. If the bearings are too damaged to read or they are missing, you can measure the spindle in the areas pointed out in the accompanying diagram I have attached.

You would need to measure the spindle with a digital caliper like part # PTW80157. You want to ensure you get the most accurate measurement possible to determine the correct bearing. I have attached a FAQ with popular bearing dimensions for your reference. If you are not able to cross reference please let me know the measurements you get and I can help.
