1st make sure your power steering belt is stiil on@ tight. if so i would suspect a bad steering rack @ pinion. do you hear cracking or popping when you turn the wheel? is there any fluid leaking from under the steering rack under front of car?the steering pump may be air locked, keep turning the wheel back @ forth to see if it loosens up any at all.hope this helps!!

My 2001 pontiac montana is having problems with the power steering i checked the power steering fluids are ok but when i am driving and turning i have no power steering and makes a loud noise


Check your engine belts, you may have a seperate one for the powersteering,

if it is a serpentine belt, it may have stretched and may need to be replaced.

it could also be the belt tensioner, when the engine is off, the belt should,

be tight, check your belt or belts for cracks, it may not be grabbing the pulleys,

it could be slipping, get some liquid soap, put it in a spray bottle and spray

your belts, then start the engine and turn your power steering from right to

left, if the noise stops, you need to change your belt. if it does not , then

it could be the belt tensioner or a pulley that is binding. good luck!

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.

Have power stering flued but no power stering


If power steering fluid is full, but the belt driven power steering pump's pulley doesn't turn at a good speed, then the power steering won't work properly. Check that the belt tensioner is providing enough belt tension for the power steering pump to do its job.

If the rack and pinion is bad, it may also cause a lack of power steering in your vehicle.

Good luck on this repair.

I just had the belts changed on my 1998 Plymouth Breeze and the power steering pump and bracket changed. I have noticed lately that there is a squealing noise coming from under the hood. Could my belts...


The belts shouldn't need to be changed again. There are a number of reasons why the belt could be squealing. There could be too little tension on the belt, either adjusted incorrectly or a bad automatic tensioner. Fluids could be leaking onto the belt. Pulleys could be misaligned or it's possible that the wrong size belt was used. I would bring it back to whomever changed the belts and explain what is occurring and under what conditions.

Power steering failed , came back on went out again , do I need to replace p/s motor


First of all, check your fluid level. If you have already done so, then check the tension of the belt driving the pump. Also, check the belt for anything that may make it slip, such as grease, oil, etc.

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.
