Hello Group, I have a 72 340 Challenger Rallye, with power steering. There is excessive play steering wheel to gearbox. Car is all original still but I need to resolve this issue. Can someone recommend a good overhaul kit if this will solve the problem or am I going to just have to buy a replacement box? Thank you.

You’re better off buying an Borgeson box, you can rebuild the old one, it’ll just end up the same way in a short while.

If it’s original I would try to keep it. If it’s only loose, and not leaking like the Exxon Valdez, You should definitely try adjusting the adjustment screw. Snug it up, and back it off a little. If it’s too tight it will bind when you turn sharply. It may take two or three times to get it right.

Also the column to box coupler can be very sloppy and they don’t last very long after rebuilding, so I would recommend a steering u-joint replacement similar to this: https://www.speedwaymotors.com/shop/steering-shaft-u-joints~14-15-574-31185

I don’t remember the diameter and spline count, but I replaced the Mopar coupler on two of my Dodge trucks and it was a great improvement.


Lastly; this article describes how to easily reduce the power steering assist and give you more road feel. I have done this mod a couple of times and Highly recommend it. http://www.moparts.org/Tech/MoparAction/PumpItDown.pdf

Doesn't it take decades to wear out (newly rebuilt) steering box? Buy then, we won't be driving gasoline vehicles? ha ha.
Nope, once they are rebuilt, they don’t last. It’s like adding sawdust to a transmission, an old salesman trick.

Did you just replace the gearbox or did you do the 99063 kit with box, pump, hoses and coupler...? Thank you.

I bought the box and hoses from Summit Racing with a 10% off deal and free shipping. I bought the coupler through Bergman Auto Craft. I bought a rebuilt pump through Yearone.

The Borgeson box is a huge upgrade.

Thank you sir, unfortunately it does leak heavy intermittently.

If you decide to buy a new Borgeson, John has more 10% off at Summit Racing.

If you don't care about having the original box, definitely get the Borgeson box. Contact Peter at Bergman and he will set you up with everything you need! Great guy and he's making good stuff for our Mopars!
