I have a 1993 YJ and am able to get a set of axles from a 1975 F-250 4x4 standard cab for free.  They come with a set of rims and 35" mud tires.  Will these axles be a good set to use for the upgrade on my YJ or should I keep looking.  I also wanted to run a SOA on these with my OEM leaf springs will this work?  I am a accomplished welder and able to do all that is needed to install the axles I just don't Know if they are the right axles, but I can't beat the price.

Thanks,

I think you should keep looking. The front axle off that Ford would be a D44 and rear should be a D60 but very wide too. For the 8 lug hardware you are not getting much axle up front and with 35's you do not need a 60 in rear in a YJ. I would suggest you look for a later model IH Scout in a bone yard as they had D44's front and rear which would work fine. You could also look for axles out of a older FSJ (Full Sized Jeep) Wagoneer as they had D44's front and rear from 63 to 91 and are about 3 or 4 inches narrower than than a std P/U axle.  

Well I am going to be going to a larger tire one day so I don’t want to waste my money twice and I don’t want to worry about breakage.  The only road driving my jeep gets is from my house to the trail which is about 10 miles.  Any more then that and it gets put on a trailer.  I have 33's on it now with a 4 banger in it and it runs pretty strong.  Of course I have all the power add ons that I can get for it.  I am still running the original gears in it.  So I figured that when I do put larger tires on it I can just put different gears it the axles to compensate.  There isn't much for rocks with in a couple hundred miles so it only goes through trails and mud for now.  What axles would you recommend to put under it if I wanted to run dana 60's.  

What axle you need depends on engine and terminal tire size. Also you have to remember that a YJ weight less than a full sized P/U so it needs less axle with same tire size. Some seem to forget that. A Ford 8.8 is a easy swap into rear and it is pretty solid up to 38's or so in a YJ and weighs a lot less than a D60 and had better ground clearance too. Also if you are running stock gear with 4 cyl and 33, it is lacking for sure at times. If you keep your 4 banger I would say 4.88's for 35's. It you install those Ford 3/4 ton axles better figure on 5.13 with 4 cyl because yu are going to add a few hundred lbs to it and a bit more drive line power loss too.  

I would say look for a 1970 through mid 1975 F100-F150 pickup, they had a 44 front and a 60 or 9 inch rear but they were a 5 lug on 5.5 inch pattern not 8 lug like the F250 and 350s. they are 67 inches from WMS-WMS. they are both high pinions too. and for the ratios it really depends on tire size.  

Better still, look for a old full size Jeep Cherokee or Wagoneer as they had D44's front and rear and they are about 3 to 4 inches narrower than P/U axles and Jeep used 44's with thicker axle tubes too. You could also look for some 70's IH scouts as they had D44 front and rear too.  

I'm running early Bronco (74 model) axles under my BroncoII and really like the width of them. A little extra stability without being too wide. Dana44 front and 9" Ford rear. They are already 5x5.5 lug pattern too.

This is a good tip too. I forgot about them but you would do well to even find one in a bone yard today with good parts on it.  

dont be afraid of going full size either the rear will literally bolt right up and its not to much work to fab up something for the front  

Why go with full sized axles??? In doing so you loose the narrower width of a Jeep off road. You might as well go with a full sized SUV and stronger frame if you go with axle width.  

again sorry for the doubt. But here in Nevada a lot of people cant go where the built full width people can go, then again it is a lot of work to make this complete
