If the axle isn't bent from being overloaded (wear on outside of tire tread), then you're probably okay. If it's bent, you'd want to replace it. Since you don't know the axle capacity, we can make a pretty good guess if we know the bolt pattern of the wheel/hub as well as the inner and outer wheel bearing reference numbers. Knowing the axle capacity is important, so you can choose the proper replacement parts.

We offer a few standard sized 2K and 3.5K axles. To recommend a replacement, I'd need to know the hub face to hub face dimension as well as the spring center to spring center distance. I'll provide a diagram showing these measurements.

Since leaf springs can flatten out over time, the best way to get an accurate measurement of their length is to jack up the trailer so the axle hangs free and then measure the length. 25-1/4 is a common length spring for a 3500 lb axle.

For spring hangers, we don't offer a 4 inch tall hanger, but the # E4139 at 4-1/4 inches would be an acceptable replacement. For the rear hanger, use part # 115917. You'll also need 4 shackle straps, part # 115208GALV and 6 shackle bolts part # TRFA73Z916DLNZ.

If you're replacing axles, you'll also need U-bolts and plates. Which ones you'll need will depend on the diameter of your axle. If you can reply with the information I've requested above, I'd be happy to make further recommendations.
