SOURCE: Power steering pump pulley removal

Go to your local auto parts retailer and buy or rent a power steering pulley puller. They usually run about $39 to do either, but since you probably will not use it much, why add another dusty tool to your box? If you rent it, the $39 is usually just a fully refundable security deposit, so you basically get to use it for free. Most of the pullers usually consist of a two section fixture that slips over the hub of the pulley, then a nut and a long shaft bolt are threaded through, and a sleeve goes over the assembly. You then turn the nut to back off the pulley. The kit should also include the installation tool, which consists of a bolt that you thread into the shaft of the pump and a nut and washer that you turn to slowly press the pulley on to the shaft. It is easier to do this job with the pump out of the car, with the pump clamped on your bench, but can be done with the pump on the car. Just be prepared to lose some skin and blood if you are not wearing gloves. The pulley is made of phenolic resin, formerly known as bakelite, and will break or chip easily, so be careful. Although the temptation will be strong to whack it with a hammer, don't give in. You can easily damage the new pulley and the pump itself.

SOURCE: 2004 pacifica impact sensors, airbags

you may not always have to replace sensors, but you will have to change the airbag module (usually under front seat, sometimes in middle of dash) To remove the passenger airbag you have to take out the dash.

Whining noise when step on gas

Sounds like the power steering pump. check the fluid level. Have someone listen under the hood while you are turning the steering wheel. If the whine gets louder, your pump could be the issue.

My power steering pump pulley is making a terrible noise, it just started sunday and we have just replaced the idler and ac by pass pulley. The power steering pulley noise comes and goes...?

It sounds like the power steering pump itself is bad. You mentioned changing the pulleys. Does the vehicle screech or whine when turning the wheel in a parked position? There is also what is called the power steering gear box. They do sometimes go bad as well. I would also look for any leaks in the power steering hoses.

Engine makes whining sound

Take the belt off and spin all of the pulleys. the bad component should be obvious. high pitch whine is usually alternator bearing for the 98 3800 its timkin part# 100ccab or it can be the power steering pump(but the pitch will change as your steering if it is that) water pump, idler and tensioner pulleys(if you have to change either one, replace the tensioner itself). if you have the supercharged model there are a few parts that can whine( or the s/c is low on oil.)

Engine whine, follows engine rpms, louder when I turn.

generally means a power steering pump issue. Go to a car parts store website and find one for your car, then find the thing under the hood, mounted to the engine and being spun by the belt, which looks just like it. often there is a cap with a dipstick and you can check the steering fluid level. if the level is way down you may have a leaking hose or other component.

about 2000 there was a shift away from the old style fluid pumps to electronic systems so do not be stunned if there is no such thing as a power steering pump for your car. but if the noise gets louder by moving the steering wheel, you still need to look at whatever is boosting the steering wheel motion to steer the car.

Whining sound on driver's side and i was told it was power steering but after new fluid put in and additive it is still whining and now it whines when i am driving straight and not just turning to the...

. Additive in a can isnt going to fix a bad pump. Make sure the sound really is the pump. Take the belt off and see if the noise goes away, if so, then spin and fell every pulley. The tensioner pulley and /or idler pulley could be bad, alternator bearings? a/c pulley bearings?

High pitched whining sound, I've already changed out the power steering pump. How can I find the problem. The belt is in good shape. The whining sound increases when th accelerator is depressed

You may have a bad idler pulley. Locate it, spray a lubricant (WD-40) behind it. You don't want to get it on the belt surface. If the noise goes away, you have found the problem.
