Do they in fact need to be mounted to the outside of the frame whereas the OEM is mounted to the inside? And do I need to have a fabricator weld a shock absorber tab to the axle?
Would the 3500lb axles be the correct size for a tandem axle Trade Wind rated at 5800 GVWR?
There is a lot to consider when ordering new axles. Load rating, bracket design & orientation, whether shock brackets are installed during the assembly process, or even come with the axles at all, torsion angle, type of finish on the components, brake sizing & type, whether the mounting hardware comes with the axles, lug pattern & of course overall dimensions. If any of these items are incorrectly spec'd, you may end up with an unhappy axle replacement experience. First off, your trailer came with 2600 lb load rating on each axle, however if you're planning any upgrades, & most of us do, you're going to want to increase the load rating to some degree. I have installed numerous axles on clients trailers over the years & all of these questions need to be answered before jumping into ordering.
