Re: What weight spring should be used in replacment?
If your trailer "frame" can handle the weight, that is one thing. But the axle AND springs have to be able to handle the weight as well. So it is a total package deal. If your springs are flattened, it tells me there is a problem. So at a minimum, new axle AND springs are the least. But if the actual frame isn't up to the task, it is an accident waiting to happen... If you don't know if the frame is capable, take it to a shop that can evaluate it and tell you the truth. Then IF the frame can handle the weight, get the new axle and springs. Most axle and springs will tell you how much weight they are designed to handle on them. Let that be your guide...
