There are a few ways to determine the axle capacity on your Jayco 5th wheel trailer.

The trailer's main identification plate will often indicate axle ratings along with gross vehicle weight (GVWR) and the unit's VIN. This plate will typically be located near the front of the trailer. Also the trailer's owner documentation may include this information.

Axles themselves will often have a sticker or plate applied by the axle manufacturer that indicates the weight rating. This sticker/plate will generally be located near the center of the axle.

If neither of these options is available an axle's diameter can give you a general idea of its weight capacity.

Typical Trailer Axle Diameters Based on Axle Capacity are as follows:
1,000-lb - 2,000-lb Axles: 1-1/2" - 1-3/4" diameter
3,500-lb Axles: 2-3/8" diameter (can have a 3-1/2" diameter, but rarely)
6,000-lb - 7,200-lb Axles: 3" diameter
8,000-lb Axles: 3-1/2" diameter
9,000-lb Axles: 4" diameter
10,000-lb Or more axles: 5" diameter

If you can tell me the specific year, model/number, and VIN I would be happy to look up the specs for you.
