My power steering on my 2000 Lasbre started make the classic noise when the fluid is low, only the fluid was not low. the power steering has worked fine but noisey for a long time. then a short time ago it stopped making that noise. then something started making a loud, loud kind of grinding noise, once in a while always in the morning. but sometimes not in the afternoon. power steering still seems to work great when turning the wheel. It does feel like some fine metal shaving is in the pump. If its the pump what all needs to be changed. where do I find instructions. what would cost appox. be? Russ

Classic pump problems
short answer is there a lot of aftermarket friction modifiers out there now than may provide relief or solutions today

the best, i my opinion is by Lucas
http://www.lucasoil.com/products/display_products.sd?iid=273&catid=9&loc=show

However, if the pump is too far gone, and by the "sounds" of things it may be, then replacement may be your only solution

the bad news is that there are a lot of re-manufactured pumps out there that when installed will make a similar noise

I find the best solution for most Buick's is a pump from the dealer

sure the part is a lot more money, but its worth it if you have o install a pump 4-5 times to get one that is "good"

as for prices
if you go with aftermarket parts
$300+ if a garage does the work
$100+ if you do the work yourself

if you go with factory parts...
pump is $500 plus 2 hours labor

if you do it yourself and have limited experience and/or tools you may find its a bigger deal than expected

  1. Remove the drive belt.
  2. Raise and support the vehicle.
  3. Install a drain pan under the vehicle.
  4. Disconnect the power steering pressure hose from the power steering pump.
  5. Disconnect the power steering return hose from the power steering pump.
  6. Disconnect the wiring harness from the power steering pump.
  7. Lower the vehicle.
  8. Remove the coolant recovery reservoir.
  9. Remove the power steering pump retaining bolts.
  10. Remove the power steering pump.
  11. Transfer the power steering pulley as needed.My power steering on my - 1fff950.gif

    my biggest worry is the fine metal shaving that is in the pump if that is in the rest of the power steering system, and remember the steering wheel turns freely and the whiney noise is gone. there is a loud noise that sounds like something is grinding in the engine area not when turning the wheel just when you start the car cold in the morning. when I start it is the afternoon some times it not there and sometime it is and then goes away. I did try Lucas oil sometime ago. It seemed to work for a while. but It a different noise now, with Metal flakes. Thanks Russ

    can I provide any additional assistance?

    you are correct... your belt is not an issue here and pump replacement will be needed sooner or latter

    did you look at the Lucas products yet?

    BTW... I am always seeking perfection and was wondering how I could be your number #1 solution

Check to see if the power steering belt is loose, a loose belt would make noise. If the belt is tight then I would wait untill your power steering pump completly fails before you replace it. You will know it has failed when you can no longer easily turn the wheel. If you just want to change it out now, click on the link below to order a replacement. The parts are $90 and the labor should run about $60 at a small garage and $150 or more at a dealer

    Here is how to replace it:



    Remove the nut that is connecting the pulley to the engine and power steering pump using the wrench. Place the drain container below the power steering pump reservoir. Remove the nut on the hose that is connected to the power steering pump and allow the fluid to drain



    Remove the power steering pump reservoir by unhooking the clips on the right and left side of the reservoir. Remove the bolts that are mounting the power steering pump to the engine using the wrench. Pull the power steering pump off the engine.



    Mount the new power steering pump onto the engine and tighten the bolts using the wrench. Reconnect the power steering pump reservoir to the top of the power steering pump. Reconnect the power steering pump hose and tighten the nut using the pliers. Replace the pulley to the engine and fill the power steering pump up with power steering pump fluid.

What causes a 2000 hyundai tiburon to have steering problems and a unbearable loud roaring noise as i accelerate


Most likely you are either low on power steering fluid, or the power steering pump has failed. Check the level of fluid, if it is low, top it off and check for leaks.

Impala 2011 steering power noise


Have you checked the level of the power steering fluid if it is low it can cause a noise similar to what you described. The power steering pump could be starting to fail and making the noise. I would suggest checking the power steering fluid level and if low, they make some fluid that has power steering fluid conditioner, supposed to help extend the life of the power steering pump, if it is low you need to follow the lines from the pump and see if you can find a leak anywhere. also I would take notice of the color of the power steering fluid, if not too much trouble maybe take a picture of the fluid and upload it here, the fluid can break down and need to be replaced.

MY CAR MAKES NOISE WHEN I TURN THE STEERING WHEEL


It's probally low on power steering fluid. If you open the hood, look on the left side right over the passenger tire. Theres a resivore there for power steering fluid. Unscrew the cap and wipe the dip stick clean. Then put it back in and pull it back out and see how far up the stick the fluid reaches. Make sure you put it in all the way so you get an accurate reading. If its low, add some until it says full on the dip stick. then put the cover back on, start the van and turn the steering all the way left and then all the way right a few times. The noise should stop as long as that was the problem. Windstars and known for having power steering leaks so I am going to bet that is the noise your hearing. It's a low toned, whining noise if it is low on power steering fluid. Hope that works for you. Good Luck.

My 2000 toyota camry 4 cylander makes a screetch noise when the steering wheel is turned all the way either direction. Why?


First check your power steering fluid for the proper level and check the belt.Also Get a Friend to sit in your car and turn your steering wheel giving you an idea of your problem area.But it sounds like the belt slipping on the power steering pump or its low power steering fluid level.

Power steering dont work to left or right


To find out witch it is,pump or rack and pinion,break loose the presure line on the power steering pump with a wench.Start the car and turn the steering wheel back and forth,you may need to loosen the nut on the power steering hose two or three turns to get the fluid to shoot out.It should come out pretty forceful.If it doesn`t,then replace the pump.If it does come out really powerful,replace the rack and pinion.

My 2000 Mazda Protege DX has a tight steering. Can


Try turning the wheel when standing still with the engine running.
If it is tight check the obviouse, has the power steering belt come off. If not check if there is fluid in the steering pump resavour. If the belt is on and you have fluid you may have a bad pump.
I hope this helps

Steering Wheel noise on cold start


this is either a loose belt, or low power steering fluid. Remember that Honda uses a diffrent power steering fluid from everyone else. Make sure it is a Honda compatable fluid, or you will get leaks.
