Especially with the newness of your PUP, look at the axle tube itself. It will be a Dexter and it will have a model number.
Cross reference on Dexter's website and their parts diagram PDFs will tell you exactly the part numbers and what the sizes are for sourcing them elsewhere. It is often on the upper side of the axle tube towards the curb side. You'll have to crawl under there but it will remove the guess work.
When you say there's a zerk on the axle, do you mean on the very end of the hub, pointing straight out when you remove the black rubber seal on the end? If so, those are Dexter EZLube hubs. Just pushing grease in there is ok for occasional maintenance but you still need to break it down every so often, especially if you're not the original owner and know the history of use and maintenance. The other concern with EZLube hubs is that rear seal is only good for so long before it will allow grease to seep out the back side and coat your brakes, rendering them useless. That seal needs to be inspected every year and certainly replaced every couple of years, certainly if it has messed up the rotors and pads. When I got my newest PUP, the PO had never inspected but kept pushing grease through, which never really replaces the old grease. The pads were bad enough I tossed them and replaced. It took a good cleaning with brake cleaner to get the rotors grease free again.
When I bought replacement seals, I got 4 extras beyond the immediate need so I have them handy as needed.
