If the screech varies when the throttle is applied it could be the bearing of a tensioner or idler pulley for the serpentine belts. If it is a high pitched whine it could be a water pump. Take it to someone with some automotive experience and have it diagnosed. Then have the worn out part replaced. Hope this helps. "G" You might want to check your belt also. My car was screeching too and it was the belt, even though the belt didn't look bad at all. I was kind of shocked that that's all it was. Simple fix. R1-guy
If you have plenty of fluid it could be the power steering pump itself going bad or it could be the rack and pinion assembly.
your pump could be low on power steering fluid, your power steering belt could have came off if equiped with a separate belt and finally the pump could have failed from low fluid, or dirty fluid
It could be. Some cars use auto trans fluid in the power steering system.
Synthetic power steering fluid from the dealer only. Do NOT mix drugstore power steering fluid, ATF, or non-synthetic fluid in your steering system. Damage to the seals/gaskets could result in leaks.
Polaris rangers do not have any steering fluid. You could grease the steering shaft while you're in there though.
You may need power steering fluid
Power Steering Belt could be loose or worn. Power steering pump could be low on fluid.
There could be many causes to a car leaking power steering fluid. There could be a hole in the reservoir, or the seals could be worn or broken.
Yes it could. If you put power steering fluid in the transmission you need to change the transmission fluid.
you could use regular transmission fluid.
The fluid could be leaking from the pump, hoses, or steering rack. Wash the steering system, then you can see where the leak is coming from.
