I ordered the wrong size. Can I get a cap with a 1 1/2inch OD diameter?

Hey Roger, thanks for reaching out!

The smallest grease cap we have is the part # DX84CR which has a 1.758" OD. Since you need something quite a bit smaller than that, I recommend reaching out to your local trailer or RV dealership to see if they can help you order the correct size.

Hey Roger, did you manage to find the right size grease cap at your local trailer or RV dealership? I'd love to hear what worked for you, as it could help others facing a similar issue.

@JonG No, I haven't found the right size grease cap.. I'm also looking for a 13" wheel with 4 1/2" 4 bolt diameter measurement across the diameter of the bolt holes.

@RogerN We don't have any with a 4-1/2" bolt pattern. How did you measure the 4-1/2"?

Center to center diagonally across the opposite bolt holes. Most are 4".

@RogerN Well that's definitely the right way to measure it. I can help you get setup with a standard hub with the 4" bolt pattern but that would also require the right wheel bolt pattern and such. If you end up wanting to go this route just let me know what your bearing numbers are and the ID of your grease seal and I'll be more than happy to help you get everything setup!
