Question:

I need to replace the bearings on my Dexter 3500 lb. axles on a car trailer. How can I tell if the spindle is a #84?

Expert Reply:

There are going to be 2 ways to find out what size spindle is on your Dexter 3500lb axles under your car trailer.

First every Dexter axle manufactured after April 2001 will have a serial number stamped on the rear of the axle tube near the passenger side, or on a sticker on the center of the axle. With these serial numbers we can contact Dexter to determine exactly what size components are on your axle. Please let me know what those numbers are if you have them.

If you have an older axle, can't find the numbers, or worry that the spindles have been changed at some point after manufactured, the best option is to disassemble a hub. If you disassemble the hub you can check the measurements with a Digital Caliper # PTW80157. You can also check the bearing numbers on the current bearings.

The Hub Bearing Kit # BK2-100 will contain the following components.

Inner Bearing # L68149 (ID 1.378")
Outer Bearing # L44649 (ID 1.063")
Inner Race # L68111 (OD 2.361")
Outer Race # L44610 (OD 1.980")
Grease Seal 10-19 # RG06-050 (ID 1.719", OD 2.565")
