Troubleshooting Leaf Spring Fit on Top of the Axle on a Tandem-Axle Trailer

Expert Reply:

I assume by flip, you mean you moved the leaf springs to the top of the axle. If this is the case, then all of the springs should sit the same. There are a few things you can check to ensure everything is in place.

If you had to weld on new hangers to the trailer frame, then I would check and make sure they are attached properly. You will also have to weld new spring seats like # TRSS238 on the top of the axles for the leaf springs to sit on. You can also use a conversion kit like the Dexter Trailer Springs Over-Under Kit, # K71-385-00, which will allow you to put the springs on top of the axles.

You should not flip the axle itself, the axles will have a slight upward bend to them and that is to compensate for additional weight on the trailer. I have attached an image of how the trailer suspension system should look after moving the leaf springs on top of the axles.

I have attached an image of what the suspension system should look like below and on top of the axles for you to check out.
