I don't worry about the
axle. I worry about the
tires. I jack it up by the frame close to the
axle as I can and support it there. I jack it enough to reduce the tire bulge but not lift the tire off the pavement. I am reducing the load not removing it. I then deploy the stabilizers and front jack and make the trailer level. I feel it is important to reduce stress on the sidewall on the
tires. I make sure it is stabilized but not unnecessary force in the frame. I want the door to stay in its original position and not be stressing anything. In my opinion if the door is not in the same position it was when the trailer is just sitting on its
tires You are over loading and racking the structure. Most of the small
fiberglass trailers I have seen use such lightweight frames that suspending them by the stabilizers with the tires off the ground will probably do them much more harm than good. Best put support on the frame close to the
axle where the frame is designed to carry the
weight.
