How to Determine Replacement Bearing for 3,500 lb Axle
Question:
I need to find out the part number for the inner wheel bearing on a 3500 lb axle
asked by: Christopher R
Expert Reply:
The most popular inner bearing on a 3,500 lb axle is Bearing # L68149, though there is only one way to know for certain because of the variety of spindles.
To do this you can 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 to measure your spindle to the thousandths of an inch where the bearings ride.
I've also added a link to a help article on common bearing sizes, as well as a link to our available bearing kits.
