Replacing Spindle on Boat Trailer Using Digital Caliper
Question:
I need to replace the Hub on a boat trailer that I have but Im really struggling to the correct one. I have taken measurements with a digital micrometer and have those measurements in both metric and standard. The spindle is trashed and needs replacement as well but I need to get it transportable. If Im not mistaken, I believe the spindle would have to be cut off and rewelded on as new. In the meantime, can you help me identify the hub that I need to replace so that I can get this thing mobile? Pictures available on request

It looks like the inner bearing you measured at 1.369" and the outer bearing at 1.059" and if that's the case you likely have a 3,500 lb axle as the inner is probably L68149 (1.378") and the outer is probably L44649 (1.063"). If you're looking for a new spindle you'd need the #84 E-Z Lube Spindle part # TRU74FR or if you're looking for a new hub you'd need the Easy Grease Trailer Idler Hub Assembly for 3.5K Axles part # AKIHUB-545-35-EZ-K.
