My power sterring makes a noise when i turn it hard over

Are you certain the grinding is coming from the sterring shaft, or is it simply transmitted through the shaft from the sterring box? Grinding of this critical aspect of controlling your vehicle is tremendously dangerous. If the noise happens when turning the sterring wheel, there is something critically wrong-get the vehilce to a shop ASAP.

Power steering makes wering noise and goes hard due to more than like been very lowe on pwer steering fluid .

1.power steering pumps normal leak fluid in the commodores and need replacing.
2.steerings always leak.
3.Also check the hose that come from the p/steer resvoir and even p/steeer cooler hoses and the metal pipe that mounted at the front of the radiator these are all very common faults

either too much, or, too little power steering fluid.

You could have air in the system, does your truck have rack and pinoin sterring? IF so it could be going out, hope this helps.

The most common problem with noisy power steering (whining noise) is that the power steering pump is defective. If you replace the pump make sure you flush the system with clean PS fluid or it can ruin the new pump.

check your alternator and your power sterring if you rev the engine and the sound gets worse it could be the power sterring pump but there are also idle pulleys that have bearings in them and can make similar noises

You might want to check the power steering fluid. The resevoir is on the passenger side toward the passenger seat it is kind of hard to find. But i have a '97 Grand Prix and i noticed that whenever i would turn sharp while going pretty fast it would make a grinding noise and i could feel my steering wheel pulling me. But the thing is the power steering never whinned or anything. So i checked it and there was absolutely none in there. So check the fluids first.

Do you hear noises while turning the wheel at low speeds or stationary? If you hear a whining noise check the power steering fluid level. A low fluid level would make a whining noise as well as cause stiff steering. If you hear a squealing noise check the power steering belt tension. A slipping belt would cause stiff steering also. If you hear no abnormal noises check to make sure the power steering belt is there. If all of the above check out ok you may have a bad power steering pump, steering gear or a blockage in a pressure line.

it sounds like a rubber bushing in the steering or suspension, also check the coil spring base at the struts

how it seems that your rack and pinion is going out making the vehicle very hard to steer. first i would check your fluid and make sure that it's full and make sure it's not over full if it's over full the unit will mess up.
