In order to replace the hubs on your 1974 Prowler camper, you need to find a hub with bearings that will fit on the spindles of your current 3500-lbs axles. Since you're looking for hubs with a bolt pattern 5 on 4-1/2", as long as your current spindles have # L68149 inner bearings(1.378" inner diameter) and # L44649 outer bearing (1.063" inner diameter) you can use the # AKIHUB-545-35-EZ-K to replace your current hubs. These hubs are pre-greased and ready to install. These hubs also use the following grease seals and races that you'll need to match, as well:

Races (included)
Inner race: # L68111
Outer race: # L44610
Grease seal (included): # 58846
Inner diameter: 1.719"
Outer diameter: 2.565"

You'll want to remove your current hubs and pull the bearings, races and seal to check them for the numbers stamped on the backs of them to find out which components you currently have. If your bearings, races and seals don't have any numbers stamped on the backs of them, you'll want to measure them using a digital caliper to ensure that you're getting an accurate measurement.

If for some reason you pull your hubs and find that you've got a different sized bearing in your hubs, please let me know what numbers you find or the measurements of those bearings and I can work to find you a suitable replacement.
