  • Steering: The key to a modern PS swap on a Stude car is a reverse rotation gearbox

    Still poundin' the Internet for info: this is bugging the @#$% out of me............

    Another poster reminded me that Stude/Avanti cars; at least 1951 and up, use a reverse rotation steering gear........meaning the sector turns counterclockwise when the worm gear (steering wheel side) is turned to the right (clockwise).

    Apparently there is a Saginaw 800 series gear with reverse rotation; namely the Chevy Astro unit. I'm thinking if there is enough underhood/firewall clearance for such an animal; make up a bracket and/or notch/box the frame as needed to keep the sector (Pitman arm) shaft in the exact same location as the stock Stude piece.

    Addendum: apparently the ca. 1995 up Astro 2WD used the reverse rotation gear...........the older guys were standard (clockwise).

        Just crossing our fingers and wishing you will come up with a bolt-in PS steering box interchange which has escaped us all these years.

        If it turns out to be the Astro, I know where there is one sitting in a field and I can have the box free for pulling it.

          Question.What are the original Studebaker steering housing made from? Cast, a forging or what?

              I have half a mind to pick up a Stude sedan just to see if such a modern PS swap is feasible. Note it will take a bit of time between $$$ and getting the proper specimin.

                I used a gm gearbox on my 53.made a bracket to mount it on top of the frame,mounted it with the output shaft vertical,changed the mast to have a bearing and rag joint at the bottom.used a short gm pitman arm.Bent to swing under the oil pan rail.Hooked it up with 2 tie rod ends and one of the split tie rod end connectors.Not sure this would work with a Stud.motor as I have a small block mopar in mine.

                  Aloha: I peruse Craig's list.A couple of hot rod Stude ads refer to using a power rack and pinion steering. My 55 Comander coupe steers hard and shifts hard so I'm shoping for a power steering. I want to keep column shift(3 speed).Does anyone reading this know about using the power rack and pinion in a Stude.If so what's it from?It might solve all of our problems.Aloha Jim Ayling---Honolulu

                      This is a noble quest. Advances in restoration and in old vehicle upgrades come from just this type of research. If you are able to come up with a workable solution you will be a hero in the Stude world!

                      Maybe Gord "MacGyver" Richmond (gordr) will see this and have some ideas.

                      Good luck.

                        Jim, a search will find a dozen detailed threads about various attempts at rack and pinion steering. You've got days and days of reading to catch up on.

                          One thought comes to mind. Instead of searching the known Universe for a reverse-rotation steering box that fits, how about using whatever power steering box that best fits the Stude location (undoubtedly custom brackets will be required), and then, if the rotation is wrong, make up a little box with a pair of gears in it to reverse the rotation between the steering wheel and the worm? You will need to alter the column anyway because the Stude (Avanti's excepted) have a solid steering shaft, and the donor car for the box had a 2-piece shaft with a rag joint. So you shorten up the Stude column, attach a small box containing two pinions (like oil pump gears, maybe?), with a fitting for a rag joint or a Borgeson joint. Going this route would also give you some design flexibility in the placement of the box and its orientation.

                          There are literally hundreds of places from which one could salvage some suitable gears; a planet gear and sun gear from an old overdrive or automatic transmission come to mind. The trick would be in ensuring that they were securely attached to their respective shafts.

                            That's an interesting idea, Gord. I have used steering quickeners on race cars, so I wonder if somebody like Howe racing already makes something like you suggest.

                            I did see this page about reverse rotation boxes, don't know if it helps:
