Inside the P/S box are whats called reaction discs. They translate the steering wheel turning force, relative to the force at the tire that is resisting this turning force. Its like a torque meter. So the harder/faster you are turning the steering wheel, the more boost will be delivered to the linkage. Thus when you are cruising in a straight line, no boost. When you are parallel parking, plenty boost.
-The problem is Chrysler made that reaction disc so soft, it boosts under the slightest provocation. In doing so, it becomes easy to oversteer in a corner due to the way our brains work. You see the corner, you decide how far to turn the wheel, you yank it over, holy cow-too far; because it was so easy and youre so excited.At least thats the way I see it. So the cure is to make it a bit harder to steer, so that you dont yank it over so far in the first place. Well That little disc has got to go. Chrysler used to sell a kit with multiple discs in it(maybe 3 or 4, cant remember). Maybe they still do. You just put as many in there, stacked up, as it takes to make your brain happy. I think I put 3 in mine-total. Mightabin 4.
-To change those discs, the box has got to come out and apart.Its not difficult or complicated.I dont recall using any special tools( it was about a dozen years ago). I had to do it twice because I wasnt satisfied with the number of discs that I installed the first time. Yeah pulling the box was a pain with headers on it. I was younger then. I had the extra disc(s), and free axcess to the hoist/shop.
-Was it worth it? Yeah, absolutely. Much more fun to flick around. And as a bonus it seemed the car had less tendency to wander on rutted roads and grooved highways.And parallel parking is no more difficult. I wonder who Chrysler were intending to sell all these overboosted A-bodies to? Mustabin young girls or old ladies.
-Some of those fasteners inside the box have torque specs and tightening procedures. That info is in the SM, even Haynes/Clymers. Do it right so it doesnt come apart at speed. After its back in you will need to center the valve body so it doesnt self-steer and rip your thumbs off the first time you start the engine. Its in the SM, too.
-nuthin to it.
