I believe the correct replacement hub assembly for your Dexter 8-259 is the part # DX38XR for a black powder coat finish or part # 8-259-50UC1-EZ for a galvanized finish.

Both of these use a # L44649 bearing for both the inner and outer bearing locations. You can verify your current bearing number by removing your hub assembly, removing the bearings, and then looking on the inside ring for the part number (see attached photo). If you have something other than L44649 let me know and I can help you find the correct replacement.

The BTR and BT8 denotations refer to the spindle, not the trailer hub. The difference between a BTR and BT8 spindle is that the BTR spindle uses a 1.063" diameter L44649 bearing and the BT8 spindle uses a 0.99" diameter L44643 bearing. In…

Answer 6

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…
