hi everyone, on my 57 f250 i currently have 8 lug front and rear wheels. i need to know which donor trucks can i get a front and rear axle from to convert them to a 5 lug set up. thanks in advance.

 

F100 or F150. These are much lighter axles & you're not a "3/4" with these.

For the rear, the Ford 9", but you will probably have to find a yoke that matches your driveshaft u-joint or, at worst, have your shaft lengthened or shortened with a proper u-joint to match the 9. If you are lucky, your donor truck will be the same wb and have a good shaft. IF you are lucky.


In front, any solid front axle from 57-60 at least methinks. Maybe more. Get the tape measure out on your spring pads.

In the front, you may be able to swap spindles instead of the whole axle.

Since this will bump the thread, you may get some better answers on the front.

Lots of work to get less capacity and smaller brakes.

 

I can't say for certain on the 57-60 but on the 48-52 for sure and also the 53-56 (I think) trucks the 5 lug brakes and drums will bolt on to the 3/4 ton front spindles. If this is true for the 57-60 that would be much easier than changing out the whole front axle. Perhaps someone with more 57-60 knowledge can chime in here. Col Flashman would know. He's the 57-60 expert. The 5 lug nine inch is always a good choice.

 

thanks for the info. i will check into it.

 

For what ever it is worth (nothing!) it would be probably almost as easy to find a 57 half ton parts truck and use the running gear from it or change your engine & cab (if necessary) over to the parts truck? Some of the ¾ ton stuff is really big (and ugly IM not so HO)
