I Think I Fixed (or At Least Improved) My Cj2a's Steering

    My father and his friends put power steering in his '46 CJ2A in 1970-71 or so. These days, the steering had a LOT of play. Most of this seemed to come from the universal joint that attached to the steering box. Replacement seemed doable, even for me.

    The U-joint was super difficult to remove from both the steering shaft and the steering box staff. Five decades, I guess.) I had to remove the steering box to get some room to work at removing the U-joint, and the Pitman arm, for that matter. When I finally had everything apart, I'd discovered more of my Dad's mysterious home-made, hodge-podge engineering (of which there is so much on this Jeep):

    -- A quarter-inch of one end of the U-joint had been sawn off, for no obvious reason. (Photo 8030)

    -- On the upper end of the U-joint, the 3/4-inch round sleeve fit over a 3/4-inch round shaft (No splines, no welds, just a slight flat spot for the set screw. Seems wrong, but it lasted five decades). (Photo 8009)

    -- The splines on the steering box input shaft had all been intentionally ground down to accept the 3/4-inch round U-joint. Also, the very end of the shaft was sawn off, for no apparent reason. (Photo 8000) _DSC8000.jpg

    I went ahead and bought a rebuilt steering box (Saginaw 5691676, $139). The shaft is 13/16-inch diameter, with 36 splines.

    I could find U-joints with 3/4-inch round sleeves for the upper connection, but not with set screws. They are supposed to be welded. I don't weld, so I ordered a U-joint with a 3/4-inch DD sleeve, then ground down two sides of my steering shaft. (Photo 8029)

    I kinda like the silver-gray powder-coat (I assume) finish on the new steering box, so left it. (Photo 8026) Note Dad's fabricated mounting plate.

    Bottom line: It works. My Jeep will never steer like a sports car, but all that sloppy play is gone.

    Unless one is a professional welder (and maybe even then) a double D with set screws is probably the safest design there is. Most aftermarket joints have two set screws and I run one long set screw all the way in so it pinches the far side of the DD into the U-joint bore.

    Nice job!

    Thanks. Yes, when I saw the DD option, I figured that's the way to go. My grinding job wasn't perfect, but even without the set screws, the U-joint can't slip off (Though I am keeping the set screws tight anyway!).

    Also, I took the Jeep for another, longer drive with some curvy turns. What a difference! I think this goes in the you-don't-realize-how-bad-it-was-until-it's-fixed category.

    Do you have any specs on that Saginaw power steering box. What I really want to know is if there is any reason that would not work on 1962 CJ5. Gathering parts for my Power Steering project. Also do you know what steering column your dad used? Thanks.

    05rider: Sorry, I know nothing about the specs. I ordered it from CarSteering.com, if that helps. I remember overhearing that the steering column from a Mustang, but honestly, they could have been talking about another Jeep, or I may have misunderstood completely. I could post photos if you think it would be helpful.

    Thanks for the response. Photos would be appreciated. If that box works on your CJ2 I don't see why it would not work on my CJ5. If I am wrong somebody should let me know. That box is at a good price.

    Thank you for the pictures, nice looking interior, but I should have been more specific. I should have asked for pictures of the under hood steering column linkage to the steering box, (not tie rods), that is where I am going to have to be creative I think. Thanks again.
