Make sure you check your power steering fluid... if it's even low, it will make a terrible noise...run it on empty too long and your can ruin your power steering pump.

My porshe cayenne 2005 has noise in the steering wheel when i am barking out of my garage, it continues for a quarter of a mile and its there at left or right turn,


Low power steer fluid. When it warms up fluid expands a little.
Or could be power steer pump is dead.
Or could be filter/reservoir needs changing. Change reservoir to change filter.
Check fluid level first

Terrible whining in the steering? What could this possibly be?


Thank you for the inquiry.
For some reason power steering fluid does get contaminated and needs to be replaced. Worst case the fluid is low and you are hearing gear whine. It's a known issue with this pump to whine when the PSF is contaminated. Needs to be checked and serviced.
Here is a procedure for you Do It Your-self-ers:
You can easily change the fluid yourself, and save a ton of money.

If you follow the lines that go from the steering rack to the cooler located around the radiator area, there's a hose that comes out of the cooler, and connects with a hard line right above the left front frame rail. The connection is a simple spring clamp.

Easy but fairly messy to change. Engine OFF, lift the front of the car to get the front wheels off the ground, put a pan under the hose line, and pulled it loose from the hard line. The bad fluid will drained out, then slowly turn the wheels from side to side a bunch of times to pump out all of the fluid from the rack. When all of the fluid is out, reconnected the line, then fill the fluid reservoir with a high quality Power Transmission Fluid. You can again, turn the wheels side-to-side to get the new fluid into the rack. Then, start the car, again turning the wheels side to side. Top off the reservoir, and should not have any more noise from the power steering pump. It will take a little less than a full quart to completely refill the system.
Kind regards,
TF

I have a 2005 ford galaxy and when the engine is on tick over there is a whining noise when I turn the steering wheel. Once you put revs on pedal the noise goes away. We have changed the timing belt and...


If it is when you work the steering it could be the power steering.
Check the fluid level in the reservoir. Centre the wheels, start the engine and remove the lid on the reservoir. Turn the steering all the way to the left. Now turn it all the way to the right. Repeat this 'lock to lock' action four or five times.
Turn the engine off and recheck the fluid level. Top up if needed.
PUT THE RESERVOIR LID BACK ON!!!
If this doesn't fix the problem you will need to get the steering rack and power steering pump check by a good mechanic.

2006 bmw 325i...where is the power steering reservior.


The power steering reservoir should be just under the oil filter housing (round black case with a large nut on the top). It should have a star-shaped handle on it.

E46 BMWs use ATF in their power steering so make sure you use the right fluid.
