Yes, we do. For the Dexter Idler Hub Assembly, Item # 8-213-5UC1, you can use spindle, Item # TRU57FR. If you are open to shifting to an EZ-Lube option, you could get a Dexter Idler Hub Assembly, Item # 8-213-5UC1-EZ, and TruRyde EZ Lube Spindle, Item # TRU37FR. Both spindles also work with inner bearings like Item # 25580 and outer bearings like Item # LM67048.

When you change your spindles, be sure to have a professional welder that knows about trailers do the work so that they are installed properly. The spindles need to be perfect in their installation so that your trailer rides safely and your tires and hubs do not wear out prematurely.

I have attached additional information and videos for you to check out.

Answer 5

A BT8 spindle would have a diameter of .99 of an inch where the bearings would both install and would have a diameter of 1.24 where the great seal would ride. That would require a hub part #AKIHUB-440-2-1K for an idler hub. A BTR spindle would have…

To determine the size of the hub assembly you need to purchase you have to determine which bearings are in the old assembly. If the old assembly has L44649 inner bearings, you would use the hub you chose #8-258-5UC1. If the inner bearings are marked…

Answer 9
