Hello Ed, thanks for reaching out. It can be tricky to find hubs for mobile home axles since a lot of them use oddball/obsolete bearing sizes. There is a chance you will be able to use a hub for the standard # 42 spindle such as part # AKIHUB-865-7-1-K. This idler hub uses the # 25580 (1.75" inner diameter) inner bearing and # 14125A (1.25" inner diameter) outer bearing. Measure the diameter of your spindle to get the exact dimensions of where the bearings and seals ride. If the bearing dimensions are 1.74 and 1.25 and the seal diameter is 2.24 then you are in luck and you will be able to use the # AKIHUB-865-7-1-K hub. If you spindle dimensions are different I am afraid we do not have a hub that will work for you and your best option will be a new axle.
