Power steering noise
When the fluid is low and you add some ... it still needs more after
you run it for awhile. The reason for that is that the pump pumps the
fluid through the lines and gets out the air in them. Keep filling and
checking after you start the car and turn the wheel from side to side
all the way.
- The bigger question is why do you need to add fluid? After
you locate and fix that leak, you can address the whine. If it is a
Ford, it may be somewhat normal. Like Drazi said, "It may be air
trapped in the line." Or the pump may be damaged from running it dry,
or there is blge in the line, starving the pump. Let's assume you have
kept up on the maintenance and have flushed the fluid when it was
dirty. Let's also assume that the pump is not damaged and you have
found and fixed any leaks. Try this: pull the fluid out of the
reservior and add one bottle of Lucas brand power steering additive,
and top with power steering fluid. I have found this stuff pretty good
at resolving many power steering problems. I'm not a big supporter of
"Snake Oil", but have had good luck with it.
- well" if it's a ford it's because they use plastic parts
in there casing's. most other car company's do the same. if that's not
the case, then your pump is reciving too much stress from turning. try
lubing up the chasis and changing the fluid completly. it wouldnt hurt
to check your line's ether. sometime's blockage can cause too much
stress on the pump too.
- First thing is why are you adding
fluid. If it has a leak then i would address that problem
first. A pump will not bleed out if it is leaking. If every thing seems
to be okay and your pump still whines. Then replace the pump. Note my
advice is replace the pump with a new one from the dealer. These so
called rebuilt pumps that you buy from places like autozone o'rielys
ect.. Are cheaply rebuilt. Especialy if it's a ford. They don't bleed
out right improper pump pressures. A good pump will bleed out almost
imediatly.With the turn of the wheel a few times. If it doesn't then
your pump will more than likely never completly bleed out. Buy a pump
from the dealer it cost more but if your like me and don't like the
noise then it's worth it.
- You probably have air trapped in the system. Bleed the air
out by revving the engine to about 1500-2000 rpms and turning the
steering wheel almost all the way from one side to the other a few
times. This should bleed out the air and take care of your problem.
- If the noise is similar to that of a dry bearing, then the
problem probably revolves around the power-steering pump itself. If the
noise you hear has a "click, click, click" to it when making turns in
your vehicle, then the problem is more-than-likely your CV joints. If
the noise is screeching, check your belt for wear-and-tear and proper
tension (see owner's manual).
I just wanted to add another two cents about the topic of bleeding or burping the power-steering system:
1. Know what type of power-steering fluid is needed for your
car. Some power-steering pumps can use automatic transmission fluid,
others have specific power-steering fluid for each car i.e. Honda
requires and suggests that you use Honda's brand power-steering fluid
(see owner's manual). Make sure you know, or the warranty from the
dealership or from the parts store may be voided.
2. Before attaching the power-steering belt, fill pump with
required amount and type of fluid, (see owner's manual) and turn the
pulley wheel by hand a few times. This helps cut down on dry turns
before they can happen. If more power-steering fluid is needed fill
3. Attach the power-steering belt with proper amount of tension (see owner's manual).
4. Turn vehicle on and proceed to turn the steering-wheel all-the-way right and left 3-4 times.
5. Turn the vehicle off and examine that the belt tension is
acceptable, and again check the level of fluid and fill accordingly.
6. Always, always check your owner's manual before performing
any maintenance on your vehicle. An educated car owner is a safe car
How long has the pump run without fluid for? There could be damage
inside to the cam an rotor (assuming it's is a vane type pump), to the
plates or it could be cavitating due to the ingress of air - possibly
why the fluid leaked out in the first place.
