Question about 2003 Chevrolet Impala

3 Answers

Replaced leaking power steering line and now steering whines.

My 2000 Impala worn thru its power steering pressure line. We replaced the line, refilled the syste, and bled the system as best as possible by turning the wheel until it bottomed out in each direction repeatedly. When the system was still a bit low on fluid and we checked for leaks all looked well. But when we filled the reservior up to its proper level it started to whine when you turn the wheel.

What could be causing that now? Do we need to replace the pump now too? Could there be another cause?

Pump condition depends largely on how much fluid had been lost and how long you drove it that way. Sometimes whine will continue for an hour or two, till all air has exited the system. If it continues for more than a day, yes, you will need to replace the pump.

Yes the pump is bad if its whinning like that.
what happens is the fluid all leaked out or at least to a starving level and burned it up .
sometimes if you just give it a few days it may go away but if it dosent then you will have to replace the pump to get the car quiet again.
there would be no other cause for the condition discribed.


have a super terrific day.
hope this helps out

thank you
jm

The system is operating normally. The fluid is full as long as there is no air bubbles in the fluid you are okay. IF the fluid looks like a foam of air bubbles is on the top, The pump is still going to low on fliud, Just add some more in.

The reason the pump is whining when you turn the wheels all the way left and right is because of the pressure put on the lines and pump .

Just make sure there is enough fluid in the system ,

Steering gear leaking in 2001 impala . What's up ?


The seals in the rack and pinion assembly are leaking due to a worn steering gear shaft. The steering gear will need to be replaced and have the alignment checked after the replacement.

Ive got a leak in the power steering box near the power steering lines what could it be


most likely it is one of two things. the O-rings on the end of the line has worn and all you have to do is remove the lines from power steering rack and put ne O-rings on. if your car uses a double flare nut style (like a brake line) then it is either the rack leaking or the actual hose leak. if it is the pressure hose you will generally see it spray. not so much on the return line. this requires replacing the part that is faulty

2005 chevy impala, the steering whel is hard to turn at low speeds, had pump and pullies replaced, was told it is not the rack and pinion or the steering box. What else could it be?


My guess would be possibly the power steering belt. Make sure it's tensioned properly and not worn. Since the problem only happens at low speed, it sounds like the system is losing proper fluid pressure when the engine slows down. Check the system for any fluid leaks as well.

Power steering leakin , but dont know where its coming from , and its whining too . but the it stops whining after i drive it for awhile , what should i do....


Whining should be low power sterring fluid.
Check the power steering dipstick and keep it in the range.
If you have no power steering fluid, automatic transmission fluid ( Dexron) works fine.
Leaks best found with a flashlight, you should not need the engine running, but you will need to get under the car, and you may need to push or bend some of the plastic sheilds out of the way to look.
Most often it is a hose, high or low pressure hose to the power steering pump that leaks.
High pressure hose has fittings, low pressure hose may have a hose clamp.

Power steering leaks from the cap


could be overfull
remove excess to the full mark on the dipstick
could be a problem power steering pump bypassing excessive oil back to the reservoir under pressure and heating and expanding the oil
take it to an accredited power steering service center and have a pressure test done on the pump
the humming noise indicates a valve problem leaking under pressure

Whining when i press gas


normally, the only part of your automatic transmission that will make a whining noise is the pump. it usually whines when iether the fluid is low or more commonly when the transmission oil filter is getting plugged up.

the power steering pump will also make a whining noise too.

turn the wheel all the way to the right and hold steady pressure against the stop. this puts maximum force on the power steering pump and, if the power steering pump is the one making the whine, it will change the sound of it. (usually louder).

if the trans pump is making the whine noise, it should sound different in neutral compared to drive. this test will really only work if it make the noise without the vehicle moving. if it wont do it at idle hold the rpms at 2000 or so.

if you decide the noise is coming from the transmission, and the transmission filter has not been replaced (assuming you installed a used transmission), replace the filter by removing the oil pan.



oh and also, if it is the power steering pump you should be able to make it make the whining noise while the vehicle is stationary. if it wont make noise unless its moving its not the power steering pump.

Power steering fluid leaking pretty good on 2005 chevy impala. not from pressure line ithink. any clues


The power steering pump is belt driven. It is on the engine where you put fluid in. There are two lines that run from the power steering pump to the power steering rack on the firewall. The fluid can leak from the pump, either of the lines or the rack itself. If you are handy you may be able to repair the problem by replacing the bad part. Wear safety glasses when looking for the leak and do not touch the fluid leak when the engine is running. The pressure is high enough to hurt you. If you ignore the problem you will eventually loose the power assist and may be unable to steer the car. Fix it now!








One line is high pressure and the other is a return line. Check them with the engine off and when you think you've found the leak staret the car and look for the leak. If it sprays like a water hose DO NOT TOUCH THE LEAK. The pressure is high enough to cause serious injury.

Loud whining noise sometimes after driving for a


Not really expensive just messy to repair. Return lines (low pressure) are much more common and they travel along the frame rail on the right side of the subframe from the power steering rack to the cooler line in front of the radiator. The high pressure line starts at the pump and travels over the top of the motor to the back side (it's a thick line with a big banjo bolt at the pump). They go too but less frequently.

If it's the return line and not the pressure line you can cut it and put some rubber hose from the parts store over the cut part with a couple clamps and that'll hold you for quite a while till you can get the line and get it installed.

The return line, done correctly, can be a bit of a bear on the ground but it's fairly quick in the air on a lift at a garage. The pressure line isn't too bad and can be undertaken by the home mechanic.
