Your spindle is an obsolete size and will need to be replaced. We have a couple options such as our Replacement Weld On Straight Spindle # TRU77FR or the 4" Drop Spindle # TRU87FR both of which are designed to weld onto a 2-3/8" outside diameter axle tube. Then you will be able to use a standard size 3,500LB Idler Hub # AKIHUB-545-35-EZ-K.

We also have some axle options if you would rather just get a replacement axle you can bolt on.

Answer 1

The #TRU77FR spindle accepts a 3 inch axle beam, and the spindle is designed to be welded into place. If the axle tube is painted on the ends, you'll want to take the tubing down to bare metal so you get the proper penetration on your weld.
