Sensitive Steering - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 72 chev 4x4 with factory power steering. It's very sensitive. I am able to turn the wheel with my pinky finger with no effort. Any suggestions on how to make it less sensitive?

The steering is one of the things I love about these trucks.

The spring in the bypass pressure relief is probably broken. On the back of the pump, where the hard line (pressure line) goes in, ot goes into a fitting that looks like a jamb nut of sorts. Remove the line, then remove the fitting, and look for a kerfagled spring. If it is in one piece, you'll want to replace it still, but with a stiffer one.

These trucks have a more primitive power steering system than what later-built vehicles have.It was great to not have to "fight" the wheel or be a bodybuilder to relax while driving.In the earlt-70s,first with cars,they started valving boxes for pressure/counter preasure to give some resistance and a better "back to straight" feel.You`re probably just used to the modern stuff.All my 4wds steer like that.

after driving my vehicle for work, with a stiff steering wheel, i get in my chev on the weekend, and it feels like i'm oversteering the thing. it may be a hazard.

Are you driving a 35 year old truck at work?If not,simple adjust yourself to what you are driving.I`ve never felt unsafe in my trucks.

Mordachai · 05-25-2006, 10:53 PM

yeah, mine is the same, I put PS in from manual, and man, it's sweeet.

Now I can actually enjoy driving the truck, instead of working hard to drive it!
( I also ditched the 3 on the tree for T350, but I still have manual brakes!!)

I think it's something you should easily be able to adjust to......

The steering on my 68 is that way, requires almost no effort. I like it!

da-burb · 05-25-2006, 11:10 PM

The brochures of the time advertised 1.5#'s of force required to turn the wheel. Look at it this way, if it required more it would mean your ball joints had siezed.

Green Monster · 05-25-2006, 11:21 PM

You can replace the steering gear with a variable ratio steering gear.

I was not happy with my sloppy worn out steering gear. Too much slack when driving down the highway. Constantly correcting. Wes of ClassicHeartbeat.com was able to obtain a custom made a variable steering gear for me. Same price as a stock replacment. I love it. The steering is soooo much more precise making driving more peasurable. The wheel feels closer to a normal vehicle, with a little more resistance than before. It's only 3 1/2 turns lock to lock as oppossed to the 4 1/2 turns I had before. I make turns quicker now. Good for avoiding road obsticles as well as parking.

Here is the thread about the steering.

That`s a great idea.It also,occured to me that these trucks have a much larger diameter steering wheel than newer vehicles.That adds to this feel.

*MisterMan* · 05-26-2006, 08:04 PM

i have a 71 gmc long bed, its the same way, orig awner said it was always like that. persopnally i hate it. when jumpin outta a conor we always go flying over into the opposing lane.... i can never feel "where" i am. looking for a way to stiffning it up also.... also soon going to shorten the steering colum. its too far in my face.

if ya find an easy way, drop me a pm.

^ ^I think your guy's trucks are worn out. ^
slack in the steering wheel and low force to turn it are two differnt things(did I say that right?)
check out ball joints and tie rod ends.
Also make sure your pitman arm and idler arm aren't bent.

if everything's up to shape, it should steer very well, but just requires less force to turn the wheel than a modern truck(or car).

My old van had a idler arm bent over 10 degrees, and a slightyl twisted pitman arm.
Once those were replaced, the 4-6 inches of freeplay in the wheel suddenly dissappeared!!
