81 Vette, replaced the steering control valve and cylinder. when I start car the steering wheel turns hard left on its own. Would this be a steering valve or cylinder issue?

SOURCE: steering wheel hard to turn; power steering fluid is full

Hi,
Intermittent hard power steering, at the begining of the turn of the steering wheel, once disturbed past the hard part, works normal.
Had fluid change, I notice a sensor, on the control block tower of the rack, is this at fault ? thanks buckleyeng.

SOURCE: ignition cylinder won't turn

I had the same problem in a 94' trooper. Basically the Ignition lock cylinder is wore out and you need a new one. Mine wouldn't turn past lock and no matter what I tried it wouldn't turn. You can go on auto zone and find the part, mine was about 61 bucks, it comes with keys and the ignition cylinder. The deal is that to get your new ignition cylinder in you have to get your original turned to off or acc I can't remember. You'll see with your new ignition cylinder that when you turn the key there is a button that can be depressed but only when the key is turned past lock and it also won't depress in start. First, disconnect battery and wait like 30 minutes. So, what you do is take a screwdriver handle and place it up against key and take some pliers or something and beat on it a couple of times, this gets the key in deep enough to where you can eventually turn it. I swear it will eventually turn, once there, take off the top and bottom plastic covers off steering wheel/unscrew electrical wires on back of ignition cylider and other side and you know the button I referred to basically you have to depress that with key in acc or off and it will slide out. If your having trouble finding the button look at new ignition cylinder in comparison to old one and you can see where the depressed button is on side closest to you, you'll see a little hole up on the side of housing that you can depress.

SOURCE: car steering wheel is very hard to turn left,

it sounds like the steering gear needs to be replaced cost varies about 500 plus alignment

SOURCE: Car makes a clunking noise when I turn to the left

YES , THIS IS CERTAINLY YOUR LEFT OUTER CV JOINT, IT'S EASIER & CHEAPER TO REPLACE THE LEFT CV SHAFT

SOURCE: when turning steering wheel to left very hard to turn

Sounds like the begining of a bad rack n pinion. We can eliminate the pump because the car turns to the right fine. There is no loss of fluid? The only thing left is the rack. It is a fairly commin issue. Use to call it morning sickness, The cars would be hard to turn in the morning or when first started but after running and warming up for a while they would start to work properly.
