Shawn, I'd be happy to help track down the right hub. The challenge is that the overall length from the grease seal to the dust cap is not usually enough by itself to identify a trailer hub. Most hubs with a 1 inch straight spindle and a 5 on 4-1/2 bolt pattern are closer to 4 inches to 4-1/16 inches in overall length, so a 5 inch measurement is a little unusual and makes me want to verify exactly what you have before recommending a replacement.
The most reliable way to identify the correct hub is by the bearing numbers or spindle measurements. If you can remove the hub and provide the bearing numbers stamped on the bearings, or the inner and outer spindle diameters where the bearings ride, we can narrow it down with confidence and avoid ending up with a hub that doesn't fit correctly.
What trailer is this for, a utility trailer, a boat trailer, or a custom build you're proud of?

Hi Heather, I can’t find any casting numbers on the hub. It is Remeq trailer from Canada that was sold with a Pincecraft boat back in 1993. The bearings are L4463. It’s a 1” straight spindle.
