too much power steering assist - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 1985 Chevy 350 with power steering. It has too much power assist on the steering. I can freely spin the steering wheel. WHAT IS THE FIX ??
Thanks

You might have better luck in the 73-87 message board...

I have taken your suggestion. I have a 1968 there is the confusion. brad

I read something on here somewhere that the newer pumps have that effect maybe an older pump will fix it maybe someone who knows for sure can help more

Welcome to the world of GM: heavy assist has long been a quality of their products.

Here's your issue. You probably have a 68 PS box. The 68-72 PS gearbox was 4 1/2 turns lock to lock (LTL). Later models went to a different ratio in the PS Gearbox, it is 3 1/2 turns LTL. The 68-72 has always been too soft or mushy for me, but even more so since most modern cars use R&P. I used a 76 box in mine and it feels much better to me. The original was so easy to turn in these trucks you could do it with your pinky. Keep in mind that if you go to a later box, they changed the hose fittings at some point and you will want to have the right ones. The hex nut on the back of the pump is interchangeable. There are some good threads on this if you do a search.
