I do not have any exact sizes on the parts used for the Dilly trailer, but fortunately all it takes to figure out the correct parts is a bit of measuring.

If you would like to send me the following information, I'll be happy to recommend an axle and bearings for you:

-The inner and outer wheel bearings
-The hub face to hub face dimension
-The distance between the spring seats, measured center hole to center hole
-Axle capacity

I've attached an image showing how to measure these parts.

To measure for a leaf spring, you'll want to jack the trailer up so that the axle is hanging freely, then measure directly across from the center of one spring eye to the other. The height of the spring and the distance from the spring eye to the center of the spring can also be helpful in finding the correct replacement. I've attached an image demonstrating how to get these measurements.

Again, if you would like to send me this information, I will be happy to make a specific recommendation for the parts you need. I've also linked you to our product listing for bearings, leaf springs, and axles. In addition, I've included two videos, one on replacing leaf springs on a trailer and the other on replacing both the suspension and the axle.
