Hey Harry! Thanks for asking.
It sounds like you have a standard 2k axle with the inner and outer bearings both being L44649. When you say straight spindle, I assume you mean it's an idler hub where it doesn't have brakes on it; that is common for axles of this capacity. For that you can use the Easy Grease Trailer Idler Hub Assembly for 2K Axles - 5 on 4-1/2 - Galvanized # AKIHUB-545-2-G-EZ-2K.
This comes with the hub and studs that match your 5 on 4-1/2" pattern, the bearings you need, grease seal, lug nuts etc. You won't need anything else aside from grease if you don't have that already: # L11380.
What kind of trailer is this? Is it a boat trailer? If so, this hub is galvanized which is good for that.

Hello Andrew: Yes, mine is an idler hub. I had looked at the hub you recommended, but in the "Features to know about" section it notes: "This hub measures 4-1/8" from the outside of the inner bearing to the outside of the outer bearing." However, that distance on my hub is 3-1/2" (with an overall length of 4-1/4"), which means that hub would be too long for my spindle. I have also looked at similar hubs, but none of them provide that critical information. Thank you, Harry van den Berg
