[Chevelle-list] Q: Jerky steering

Wed Apr 18 02:35:12 MDT 2007

Sorry! Should hav read it more care carefully!
I found a used pump for $15 (a Volvo 240 pump that's identical to newer chevy pumps) so I'll try that first.
If that doesen't help I'll change the gear box!
I'll keep you updated.

  He is talking about the gear box where the steering shaft goes in one way and the shaft for teh pitman arm comes out the bottom.  There is a worm gear inside with ball bearings that run along it.  See this article:

    Sounds like you're talking about another type of power steering pump!?
    Do you mean the pump vanes??

      It is possible that the steering box has developed what is knowing as 'stick slip condition'. That is the balls in the guide tubes and sticking and binding, especially when engine is cold and just starting up after sitting for a few hours.  After warm up and getting the balls moving the condition will go away but will return after a long cool down.  The tubes in the steering box are worn.  You could replace the tubes and balls in the steering box and correct the problem but at the age of the box other parts are also worn.  A replacement unit will correct all worn parts.

        Nope!
        I guess It's been there since I bought the car but I didn't notice it in the beginning
        because the engine was idling quite high! Now when the carb is OK and
        the engine is starting to act normal I've noticed this!
        But it's also possible that the problem have popped up lately.

        My guess is that it's the steering pump.
        If it's the pump? Is it enough to buy a gasket kit to get rid of the problem or is it
        something else (hard to fix) that's worn out or broken in the pump?

          Did it start after replacing the hoses?  Could have air in the system.

          The belt is new, the fluid is fresh and at a proper level, the hoses to/from the pump are new!

            You don't mention if you have power steering or not but low fluid or loose p/s belt can cause this if so equipped.

            Hi!

            The steering's a bit jerky at low rpm's, like when I'm parking the car!

            Something wrong or normal?

            The steering seems to be working fine but I can feel pulses/vibrations

            in the steering wheel & the wheels move a bit "nervous" when steering.

            Best regards
            Pelle
