steering gear box question
so for some time i have been wondering how hard it would be to swap over a power steering gear box from a later model truck like an 88-98 truck over to my 72 gmc. my 72 already has power steering, its just that i like the stiffer power steering of the newer trucks rather than the effortless power steering of my 72 gmc. thanks

Re: steering gear box question
i just hate how light my steering is on myn 72 compared to my 01 tahoe. i just want a bit of a stiffer feel to my steering is all and i thought a gear box from an 88-95(maybe) would do the trick.

Re: steering gear box question
the amount of power assist is in the pump, not the box.
Remove the line from the high pressure side of the pump (the steel line fitting) then remove the fitting that is left there, a spring will pop out with a filter. Clean the filter and install a stiffer spring from a junkyard vehicle. |

Re: steering gear box question
Ok, so now i'm getting some conflicting info. Anyone else have imputs? Ticker, captain, cableguy? Changing the gear box is fine, but i would like to know for sure.

Re: steering gear box question
I replaced my steering gear with one from a 73 - 78. It was a direct bolt on. It is 3.5 turns lock to lock VS 4.5 on the 72 gear. It feels stiffer. You can use the gear from 79 - 87 as well but it has metric o-ring fittings. You either need adapters or the lines from the later model if you use the 79 - 87 gear.
I did read some posts where people said it will not turn as sharp with the later gear. That is not the case with my truck. It turns all the way to the stops on the control arm with either gear. There is no difference in turning radius. I did use the 72 pitman arm.

Re: steering gear box question
my truck has a caddy engine in it, and on that engine is the steering pump off the same eldorodo. When I first did the swap, the steering was way over assisted. sping the wheel and let go and I swear it woulda kept on turning. Gave you no feedback of what was going on under the truck. I was told that this spring was too weak, and possibly broken. The weaker the spring, the more assist you will get.
I then took he spring out of the pump that was bolted to the Pontiac 350 that was in the truck when I got it. Upon doing that, and nothing else, the assist level was reduced, and feedback was improved a lot. Maybe the spring won'd to anything... but is sure did on mine. |

Re: steering gear box question
You need more caster. Have your truck re-aligned with 3-3 1/2 degrees caster and it should feel a lot better.

Re: steering gear box question
As andy put it i am getting too much assist. I want less assist. Since swapping the spring seems the easiest thats what i'll do first
