I may have a solution for you, but we do not have any hubs that are compatible with the # LM48548 inner bearing that you've currently got in your hubs. Additionally the # 84556UC3 is not going to fit your spindle because the # L68149 outer bearing it contains is going to be slightly too big.

You could continue to use your old hubs and simply replace the bearings with the # LM48548 and # L44649. For the races, you'll want # Replacement Race for LM48548 Bearing # LM48510 and # L44610 and for the grease seals you'll need Grease Seal - Double Lip - ID 1.719" / OD 2.565" - for 3,500-lb Axles - Qty 2 # RG06-050.

It wouldn't let you switch to new wheels with a different bolt pattern, but using these parts would at least allow to replace the internal components of your hubs and get the trailer back up and running. If you wanted to go with new wheels, just let me know what the existing bolt pattern is and I can help you locate a good replacement set!

The inner bearings should be #LM48548 (1.375 inch inner diameter), outer bearing should be #L44649 (1.06 inch inner diameter) and the grease seal should be #58846. I would recommend you pull your bearings out to verify that but that SHOULD be what…

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…

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…
