Regular readers will recall that last month we documented the procedure for a Saginaw power steering conversion on an FJ-45, and gained more steering control, at less effort, for our pains. This month, we focus on the axles. The differentials come from a '77 FJ-40 with front disc brakes; our '65 stocker came with drums.
Both front and rear get new 4.88:1 gears, while the front receives new Marfield axles and a complete rebuild. "From hub to hub, it'll be totally fresh,'' says Downey Offroad's Jim Sickles, the buildup's architect. That means rebuilt steering knuckles, new rotors, calipers and Warn hubs-the works. The rear diff is already stuffed with an ARB, so when this particular FJ is finished, it should be plenty stout on trail. The rear will also be prepped for its imminent disc brake conversion.
