Hi Michael; the Replacement Grease Caps for Dexter/Tie Down Engineering Vortex Trailer Hubs # DX66UR have an outer diameter of 2.32". Do you have Vortex hubs on the wood splitter?

Not Dexter Vortex. They look very similar. I can't see the brand name but the caps are smaller... Thread diameter: 2 5/32 " or 55mm Overall Height: 1 3/8" or 35mm Outside ring diameter: 2 5/16" or 60mm Thank you

@Michael it doesn't look like we have anything that matches, can you see a brand or any other kind of part numbers on the hubs? If the wood splitter manufacturer is still in business you can try asking them to see if they know of a replacement as well.
