JEEP POWER STEERING SWAP
Here is the whole system hooked up, tested, and ready to rock. A little cleanup and paint on the power steering pump and it looked like new. A drivebelt for the pump was sourced from a 1976 Buick Skylark with a 231 V-6, Master Pro part number 7370 from O’Reilly Auto Parts. The steering shaft was a perfect fit with a smooth rotation thanks to the universal joints. A little reassembly of the fender, and the Jeep project is done. There’s more than one way to do everything, especially something custom like this power steering box mount. John Cappa also used a Saginaw power steering box on his flatfender, but instead of fabricating a plate, he welded tubes to the frame to mount the steering box. AN-6 fittings and hose were also used for the high-pressure line, along with a basic 11⁄16-18 to AN-6 adapter for the steering box and an elbow. Our friend RJ used the Advance Adapters weld-on bracket to mount the Saginaw steering box to his CJ-3A frame. He was able to have a local snowplow parts dealer form him power steering lines that were routed through a strategic hole cut in the grille. This bracket takes some of the fabrication time out of a power steering swap, but requires a welder who knows how to weld cast iron effectively. If you want power steering but don’t want a steering box visible on the front of your Jeep, you have options too. You can use a Ford reverse-rotation steering box along with one of Herm The Overdrive Guy’s mounting bracket and pitman arm kit. The box mounts behind the front crossmember and behind the grille, out of sight. This Jeep is outfitted with a Chevy 4.3 Vortec V-6 and uses the factory power steering pump on the motor. From the outside the Jeep looks like it hasn’t been modified. This is an example of a high-mount Buick power steering pump that is a little more common, at least in the junkyards I pick through. This style is needed on a Buick motor to use the Ford reverse rotation steering box and still have room for the hydraulic lines to fit. Some of you may recognize this iconic Jeep as the Killer Bee Jeep. This Jeep’s steering box is a hybrid compilation of a Scout box stuffed with different internals. This particular box is also set up for hydraulic ram assist. The box is mounted way out in front of the Jeep to accommodate the front wheelbase stretch. The owner, Ned Bacon, said that in all of the years that box has been mounted there he has never had a problem smashing it on the rocks. Our buddy Sammy Sievert’s tricked-out CJ-2A is outfitted with a steering box from a Jeep
TJ. It was mounted up high so that the steering shaft would clear the front crossmember without having to cut a hole in it, and so the pitman arm was up and out of harm’s way.
The grille did need a little trimming though. He made a custom bracket for the Chevy 350 under the hood to mount a compact power steering pump out of a Nissan Altima. A hose shop was able to silver solder the factory TJ and Altima hard lines into a high-pressure flex hose to link them together.
