Expert Reply:

I checked with Lippert and could not find any information on NV304664. Do you know the capacity of the axle? If it is a 7,000 pound axle then the likely inner bearing is # 25580 and the outer bearing is # 14125A. If a 2-1/4 inch seal diameter is needed it is a 10-36 seal, # RG06-070. Or it could also be a 2-1/8 inch diameter seal # RG06-090.

If it is a 3,500 pound axle it likely uses inner bearing # L68149 and outer bearing # L44649 and a 10-19 seal # RG06-050.

To determine which hubs will fit I really need to know the inner and outer bearing numbers stamped on the sides of the bearings. If the bearings are not available you would need to measure the spindle where the seal and bearings ride using dial or digital calipers. I have included a picture that shows where to measure.
