I just bought a 1987 fj60 and I just sold the axles from my 85 runner. How much trouble would it be to put the fj60 frount axle in the runner? I have a mini truck wide rear axle for the back. Would I have to move my spring perches? What about the steering?

I don't know 4Runners that well but I'll take a stab at it. I would bet you'll have to outboard the springs on the frame to match the width of the FJ60 axle. Further, since the Cruiser axle is spring under while the 4Runner is spring over your gonna have to relocate the spring perches on the axle. Finally I would plan on adding high steer arms to the axle to get the steering linkage over the springs. Plus you'll need to swap in an IFS steering box to make the steering system work with the crossover style steering on the Cruiser axle.
But after all that I can't see how that's better than the stock 4Runner axle you had to start with. The birfields are the same, same knuckles and brakes with only a larger diff in the Cruiser axle. But the Cruiser diff is low pinion while the 4Runner axle is high pinion and the 80 series elocker drops in. I would still do a crossover steering conversion if your truck has push/pull steering but other than that using a FJ60 axle seems like a step backwards to me...
HTH,

The runner is gettin parted out. It's still drivable but The axles for it are leaving this comming weekend. I was just trying to see if it was an easy swap. I only wanted something to stick in the frount so that I could drive it around until I sell the engine and tranny. I have the cruiser axle at my disposal and that is why I was going to try it.
