Is Rack and pinion on a 64impala worth the expense

IMO, installing a R&P is much more disruptive than replacing the steering gearbox. The only possible argument I can see for R&P is if you have an unresolvable clearance issue between the steering box and radiator. That can usually be avoided by careful selection of the radiator and/or steering box.

Have you changed upper a arms? The integral power steering boxes require approx +4 degrees of caster that can't be achieved by the original stamped steel ones (they max out at about 1 degree).

NO NO NO NO NO NO....Get the DRIFT ?? NEVER...I have a complete system (got it for a backup) I would not GIVE you..as it is not a safe thing to put on your car. 1. What is does : replaces a push pull slave system with a bolt on (hahaha) rack and pinion (flaming river/Unisteer) 2. What is DOES NOT DO : make your car handle better, track better, drive better...it made mine unsafe to drive, so have removed it. IMHO..either replace the stock components...OR choose the Global West conversion (converts you to a borgeson unit with bump steer elimination ..includes a new sway bar). Several on this forum have made the same mistake. Agree with replacing the stamped steel arms..many vendors including Global West. VIsit their website to look at the videos. Good luck

I had the same problem with one of my Corvairs. It is called "bump steer", and is caused by the center drag link being out of alignment with the geometry of the steering. Mine was the result of using a "grease able" ball bearing idler arm. Once I put back a NOS Chevrolet part, all the problems went away. The shop that did my alignment diagnosed the problem after they did the work, and took it out for a test drive. They were an old shop with Bear equipment. He even had a tin "toy" that he could demonstrate what was happening with the wheels. One of my cars, was the last car that the shop worked on before the owner closed and retired. When I came to pick up the car, he gave me that tin demonstration toy. I would post a picture of it, but right now, I don't know where it is. If I come across it, I will post a picture of it. It shows how the tire/wheel move to a "toe in" position when the car bounces as it goes down the street.

Is your present steering completely stock?

A rebuilt front end handles well if the control arm bushings /sway bar bushings, etc are all new. Don't even need expensive poly kit.


Also many people forget suspension, drop spindles change your geometry - lowering springs might be better for that.

And please remember to adjust your steering box per factory specs. It needs the worm gear and lash adjusted in that order with pitman arm disconnected using a fish scale at the steering wheel. The book outlines the procedure well.

Once all that is done, and alignment is done correctly, and well balanced good tires, car should handle like new if frame has never been hit.

I think you will find a lot of people who take issue with that statement.

Lowering springs "raise" the control arms with respect to the rest of the suspension. How can that NOT change the suspension geometry?

Drop spindles leave everything exactly as it was except for moving the wheel axis up. The wheels can't really move up because they are in contact with the ground, so the rest of the car moves down. Nothing else changes.

Drop spindles do NOT change the steering geometry. Short springs changes the geometry.

Dropped spindles could affect bump steer if the steering arms no longer remain in the same plane as the original spindles. In other words, you want the tie rods as close to parallel with the ground as possible with the car at ride height.

it's possible my statement about dropped spindles is inaccurate, all I know is that after installing 2" lowering springs on original spindles, my handling seemed to improve. Might be in my head.

Lowering with springs or any other way may improve the handling just because you are lowering the car's center of gravity.

Agree Ray, I have not noticed any negative side effects by going to lowering springs. I got them new versus trying to cut a coil from the old springs.

Car handles excellent with all the attention given to it that I posted above.
