    1/2 ton workshop trailer axle - solid or hollow?

    ozrob in his post here indicates his axle was hollow.

    I made arrangements with my local mechanic to extend my axle for me to match the defender track width. He drilled a 7-8mm hole in it and thinks its probably a solid axle. It certainyl feels solid based on its weight, but if the walls of the tube are really thick it will have a bit of weight anyway.

    I don't really want to keep drilling - can anyone confirm whether all of the axles of 1/2 ton trailers are hollow? Anyone know what the thickness of the tube is? ie. do I need to keep drilling?

    The axle is 48mm think - could you sleeve it with 48mm ID tube? Would that have the necessary strength?

    I've made quite a few different size trailer axles by chopping out diff centres and sleeping pipe over the ends and welding them together. You would have no trouble with extending yours. A piece of 50 mm NB pipe with extra heavy wall of 5.4 mm would fit nicely. Weld around the ends and drill and plug weld where the cuts are made.

    My suggestion would be knocking up a new one out of solid square with flanges on either end, this way you can fit defender stubs......than you can fit defender hubs and if you are really keen fit defender calipers and have electric over hydraulic brakes.......but brakes could be an over kill for a 1/2 Ton. I have this axel set up on my camper trailer.

    This way you have you old axle if you want to return it to original.

    Are you extending the mud guards to accept the wider track?? If so I'm guessing it won't be returned to original.

    Sorry - should have been clearer - hole is 7-8mm deep

    That would make it very thick walled tube.

    I doubt they would be solid. The axle of he 1 ton is hollow. It must be. I can lift it.
    I have seen a few 1 ton trailers that the owners have replaced the axles with new commercially available axles. I reckon that is the way to go.

    What are the legalities of running spacers on trailer hubs? Have you looked at adjusting the track width from that perspective?

    If the axle is one piece from end to end it's more likely to be machined with the bearing stubs from solid. If the stub axles have been welded on it will be more likely to be hollow. If it were actually machined in one piece from hollow bar it would be visible under the bearing cap.

    I don't know if it is legal, but that is what the army did when they fitted Land Rover wheels to Jeep trailers.
