If you're talking about the solid axle that came with the 84/85 4Runner then the answer is no. The mini truck axle is too narrow for a FJ Cruiser. You will need to make a custom width housing and from there you can use Toyota knuckles and steering to complete the rest.I have seen a picture of this before, but is there someone who is doing this in a kit form? I love the look of the FJ, but would enjoy the extra space of a 4 Runner.
