Power steering hard to turn on 2004 pontiac grand prix gt what would be the problem

Thanks for choosing FixYa and welcome. Check to make sure your power steering fluid is not low. Make sure it is not leaking also. If that is not the case, you probably have a bad power steering pump.

Check your power steering fluid.

The power steering pump is belt driven so look at the front of your engine ,there is the alternator,power steering pump,the tank for the fluid can't be far from the pump .

there should be a cap on drivers side that says power steering fluid on it un screw it and check level on the dipstick do not overfill

Look down in between the fire wall and the backside of the passenger side of the engine. you will eventually see the powersteering reservoir.

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.

wheel off /steering turned hard left /loosen trackrod end and remove/open both clips remove boot and replace .adrian,,,,

did you over fill it ?? does the pump whine at all if you over fill them the can mess up the pump by building up pressure and being over filled thers no where for the excess to go and bam pump may freeze up and have to be replaced and sometimes you can drain the excess and be ok

If you look and see the hydralic line from the rack & pinion going up to a box, that is your power steering pump
