Just Replace that 1st,its around 10-$13.00,If your problem still exsists,Your powersterring pressure switch may haved a loose connection or has went Bad.Try replacing the switch before buying a new power Steering Pump,The Power Steering Pressure Swith is around $35.00.Or Go Ahead and Get a New Power Steering Pump after you have changed the filter.Power Sterring Remanafactored Pumps run around $75.00- $90.00,there are 2-Types of pumps to Fit your Model, 1-with Vacum Assist,And 1-With Hyroboost.

Power steering pump is making a lot of noise, especially in the morning when it's cold outside.


It is the pump itself making the noise, or is it the drive belt slipping on the pulley? Sometimes the belt just need tightened, or replaced if it is glazed.

Replaced power steering pump in 2004 accord. Steering goes in and out while driving. rev up motor to about 2000rmp and steering works fine. belt appears to be tight and in good shape.


Low on fluid ?? Air in system?? wrong type of fluid?? bad pump?? while car is running and in "park" try turning wheel from left to right all the way in both dirrections,, do this a few times then check for any leaks... then with engine "off" check your fluid level... if nothing fixes the problem then concider this> bad pump "OR" bad steering rack!! Oh please make sure that none of your power steering hoses are kincked or squashed restricking the lines !!!. Good Luck!!

Did you check the belt? When it is not working, is the power steering pulley turning? Is the power steering fluid level OK?

2004 F150 2X4 crew cab The steering was hard then works fine now its back to hard again have no idea where to look the fluid is full. The pump whines when it dosent work some time just at a lost would...


It sounds very much like your power steering pump is going out. It was very good to check the fluid, something else that you may want to check is the tension on the belt that is turning the power steering pump. In few cases a worn belt can lose it's grip on the pully, especially if it's cold outside. Also, sometimes the tension pully is bad and isn't able to keep the belt tight enough to get a good grip on the pully.
If you are sure the whining is comming from the power steering pump, you will most likely have to replace it.

I hope this helps you.

Power steering only works when I rev the motor do i need a new pump it drives fine except when i turn i have to rev the motor or i have no power steering


It may be a bad pump but it could also be a simple as being low on fluid or needing a new belt or belt tightning. Check your fluid first and make sue the belt is good and not streched out. If this all checks out then replace the pump.

I have a 2003 chevy blazerthat has power steering problem no leak


There is a "pressure regulator" located in the pump just behind the high pressure line that directs high pressure fluid to the steering rack when you turn the steering wheel. It sounds like the regulator valve is sticking and not sending the high pressure fluid to the steering rack when you turn the wheel.
You can remove the pump and clean the valve, reinstall the pump and flush the steering system with fresh fluid or replace the pump and flush the system with new fluid.
Good luck.
