yes they are full width unless it is a 77 and older bronco.....77 and older broncos were smaller and about the same width as a stock cherokee axle.

78-79 broncos have cast wedges that cannot be cut off. not good for axle swap unless you are gonna run modified ford radius arms.

ALL f-150 axles are full width.......

your best bet would be the waggy d44s front and rear, 77 older bronco axles, or fullwidth 77 and older f-150/100 axles.....have welded wedges that can be cut off.

 

I'm running waggy full widths with 4:10's and rear locker in my MJ. I kept the 6 on 5.5 bolt pattern. Everyone knocks low pinion front axles but this thing has been a very tough axle I have been trying very hard to break something and so far that has not happened. I had 35x12.5x15 on it with 10.5 wide offset cragars on it and Bushwackers covered the tires perfectly. I've since switched to soft 8's and 34x10.5x16 Super Swamper LTB's and they stick way in the flares looks kind of stupid might end up getting wheel spacers. With that being said the waggy axles aren't much wider than an XJ's and lock out hubs are nice with bigger disc brakes I'm running its a nice set up. The front axle was swapped doing a front leaf conversion with revolver shackles it works quite well but I have a 3 link long arm set up, pre runner shocks, 8" coils, double shear trac bar, etc pretty much everything I need to build it back to coils and swap the revolvers to the rear which I'm starting on soon like hopefully within a week. $200 for the complete front and rear waggy axles from the you pull it their cheap and if you can weld/fab I would recommend this route for the easiest swap. Matter of fact there is a waggy at the junk yard now that I believe the rear axle is not the one with the offset diff I'm thinking about grabbing them for future builds. Hope this helped!
