How to Find Replacement Hubs With 4 on 4" Bolt Pattern


I need 4 on 4 hubs for a 3/4inch axle that is 5 1/2inch long


Expert Reply:

There are hubs available with a 4 on 4" bolt pattern but the measurements you gave are not what is needed to find them. Instead you need to know the weight rating of your axle, and also what bearings your current hub has. You will need to take apart your current 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 and grease seal ride.

You can use the photo I've attached to see exactly where you need to measure. If you get back to me with this information I'd be happy to try and help you find the correct hub.
