    Re: Gm a body Jeep steering box swap

    do you know what specs were used to align your car? old cars have less castor then newer cars - thus, the box is going to react 'faster' to input to overcome that castor. Put as much castor as you can into it, if you want the cheapest 'fix' (and you'll love how it handles), do a b-body spindle conversion. Find a 9A brake kit (cop car, Impala) and you'll get better brakes to boot. CPP sells the kit - you can shop and do a bit better, but it's good to know what the upper dollar figure is. It changes the spindle length (taller), lowers the car about an inch, and the conversion upper control arms give you more castor.....

    yeah, oops - not camber - that said, the longer spindles give you more camber gain (that is, the wheel tilts in more as the suspension compresses)... so camber is there...

      Would be nice to have someone move the steering wheel while you are looking for the leak.
      a bungee cord at full lock usually is top pressure. Like I said, I dont know why a Jeep conversion would be better, but if you have leaks you are not getting the proper flow to that box and might be sucking air as well.

        like I said, faster steering response, removes variable steering, fewer turns lock to lock. People (still) seek the box out of the Monte Carlo SS and the Buick GNX to upgrade the A-bodies - but those are rare and expensive. The Jeep box is close to those most desired boxes and as common as a SBC (and cheap - to the point where you could buy a Jeep with the box for less than the cost of the 'right' box).

          But standard replacements give you the option to go from 2 1/2 to 4 turns lock to lock and can get a remanufactured for less than 100.00.

            I think you're overlooking something. The Jeep box IS a GM designed and built box.... there is no difference, it's just a cheap way of sourcing the box from a wrecking yard.

              Caster is what you want to look into.

              General rule is heavy cars like less caster, light cars more, but with modern tires etc. 5 degrees positive is in my experience about right for an A-body to handle nice. Too much and the car starts driving you, not you - it.

              Again, caster is what is desired, the aftermarket a-arms get you that by putting the upper ball joint rearward more than what you could get by shimming up stock a-arms. Ditto on the rest of it, not needed for a street machine/cruiser but makes a big difference for spirited driving if you wind up going that way, my El Camino done in '95 was some of the best effort spent on the car.. 1LE rotors, long gone from the GM parts counter but available Chinese, are 12" dia. and have the 4 3/4 bolt circle you'd need.

                Re: Gm a body Jeep steering box swap

                Yea that steering box cost me 20 or 30$ and the lee kit cost I donít even know how much. Maybe 60$ 70$ total guesstimate when Iím done. I just need new hoses and the fittings on the box then everything should be peachy.

                As as far as the Jeep box I read up on this swap because itís one of the cheapest to do but requires another step or 2 because of the whole standard and metric threads you have to deal with.

                im paying for it with time I guess. Whatever I like trial and error..... really good at trying. And really good at erroring

                but seriously Iím starting to feel that the 200$ plus to rebuild my box to newer style specs might have been smarter but then I have a car I canít drive or move till the part comes back

                  And Saginaw built the gm box and the Jeep box. Same box but different internals. Jeep just happened to use that same box in their vehicle and we get to take them from the junkyards across America.

                    oops... correct, castor.

                        And, as noted by SBG, the camber gain w/ the mods is awesome. The mentioned El Camino with (now old-school) 265-50 front rubber became a whole different car under hard driving.
