Power steering filter


Is it full of power steering fluid ? How are the hose's high pressure and low pressure ? Did you bleed the air out after changing the pump ? There is no filter .
Verify power steering fluid level per operating specification. Refer to Checking and Adding Power Steering Fluid.
Start the engine. Rotate steering wheel from left to right. Check for sign of cavitation or fluid aeration (pump noise/whining).
Verify the fluid level. Repeat the bleed procedure, if necessary.

In my 1996 toyota rav4 mainly when I am parking the car the car makes a noise when turning the steering left or right. What that could be?


Hi there !

The noise is coming from your power steering pump, And it usually happens when you have low power steering fluid or burnt fluid or bad Pump. check for fluid level and make sure its not black. Good luck

While turning the steering wheel there is a whining sound from the motor. What is it?


you can hear your power steering pump working and if it's whining, it may be low on fluid.
Check the fluid level with the engine running and be very careful of moving or rotating parts.
Locate the pump and check the level (the cap will usually have a dipstick to measure the level attached to the cap and you read it the same way as your engine oil dipstick). DO NOT overfill the pump as it will just leak out and cause other issues.
If the level is very low, top it up then work the steering from side to side a few times then recheck the level. Careful, power steering fluid can get very hot!!
If the fluid in the pump looks dark or black, take the vehicle to your local mechanic and have the fluid replaced and the system flushed.

Pontiac Grand Prix GT grinding and whining noise when turning...


If you have a warranty from your dealer, you paid for it, or whether it came with it, it doesn't matter, you MAKE them honor it. Take it back there, and MAKE THEM FIX IT! This shouldn't be your problem if you have a warranty. If they aren't honoring it, threaten them with the BBB or court. They will shape up.
I would say power steering pump.First check to make sure there is fluid in the reserve tank and at the proper level if not top it off and whine should stop.If level is correct then maybe try flushing with fresh fluid.
3.8L engine the power steering fluid was never toped/checked.. because it is a pain in the *** to get at (behind the hot as hell alternator), so it probably ran dry, top it up is probably all you have to do.. if the whining presists then you will have to try and bleed the air out by jacking it up, engine off, turn the wheel one side to the other about 25 times.. if that dont quiet it up then you will have to replace the power steering pump.


Power steering pump / fluid level is not hard to check - it is located below the alternator on the passenger side of the engine bay. You need a light to see it. You can get your hand down from the top of the engine to loosen and remove the cap/dipstick.

Our 2002 ford windstar lx has a groaning noise coming from the power steering. It is hard to turn the wheel at times and the groaning gets louder when at full lock left or right. fluid level is fine and...


if fluid not coming out then the pump is likely toast
go to salvage yard and get a new one if you have tools and time remove the pump your self for added savings and a great learning experience and hell if it comes off easily enough you can put it on your van

remember if you break it at a salvage yard it doesnt cost any thing
and theres allways another in the truck right next to the one your working on

check with dealer for years to look for
as they used same pump from year to year

1997 chevy lumina-very hard to turn to left


Most of the time the pump will make a whining noise when used. this is a warning for a bad malfunctioning pump. if there is no noise during a hard turn, it will most likely be an issue with the steering assembly. heres a step by step guide on checking the pump.


Step1 Check the fluid levels of your vehicle first. Add power steering fluid if necessary before you proceed any further. Step2 Connect the power steering pump and hose to the pressure gauge and shutoff valve. Fit the hose to the power steering pump correctly. Make sure the shutoff valve is open before test the power steering pump. Step3 Idle the engine while turning the steering wheel all the way to the right and all the way to the left to release any air from the power steering pump. Step4 Close the shutoff valve to check system pressure for about 5 seconds. If the shutoff valve is closed longer than 5 seconds, your power steering pump can overheat and this can cause damage to the pump itself. Step5 Compare the pressure reading against the manufacturer's specifications. If the pressure is within limits, your power steering pump is working correctly and you're ready to roll. Step6 Troubleshoot if the pressure reading is not the same as the manufacturers specifications. Consult the manual for your vehicle or for your power steering pump (if you just installed a new one) to determine the source of any further problems.
