Power steering fluid DARK in color and buzzing when turning
I've had my Focus since 2006, the power steering originally started buzzing on 5/23/09, and at the recommendation of a friend, I replaced the power steering fluid (MY Focus Manuals states that Mercron should be used, so i did).
Well, it started buzzing again today, on every turn that I made, left or right at speeds from a few MPH all the way up to 40 or 50 MPH. I popped the hood again and took a sample of the fluid and compared it to a smaple out of the botttle:
What came out of my Focus is the stuff on the left, the light red is the bottle sample. I also noticed that it seemed to be collecting some extra "Crud" on one of the belts with the spring clip on it that runs to or from the pump.

Re: Power steering fluid DARK in color and buzzing when...
The fluid does look bad. It should smell pretty awful also. I sounds to me that the pump is going bad. How much of the fluid did you change? The majority is held in the rack and pinion. If you want to try to squeeze a little more life out of it try mobil 1 synthetic fluid. Should bring the pump temps down a bunch.

I have a 06 SES ZX4, same foaming and whining, burped fluid out the cap, progressively worsening in the cold weather. After reading several blogs, found the Ford TSB 08-18-9, and looked at my reservoir O-rings. The outboard ring looked bad, inboard was visibly OK. Replaced both, fixed my problem (Oreilly Auto Parts). Another blogger said he found a filter in his reservoir, mine did not have one. Also, fluid is dark, will be flushing very soon. Car has 130K miles.
It sounds as if you have a volume of air in your power steering system. This is causing the bubbling and also some of the noise you might be generating when you turn the wheels hard right or hard left. This air might have been introduced if your old belt was slipping so much that the pump was essentially not operating and fluid wasn't regularly circulating throughout the system. Another, more expensive possibility is that your old belt was slipping because the power steering pump itself was starting to fail, and the new, grippier belt is turning the damaged pump and showing you its lack of functionality.
The first and easiest thing to do would be to bleed the system. Open the hood and take the cover of the power steering fluid reservoir. With the engine off but the steering wheel unlocked, slowly turn the steering wheel all the way to one side and then to the other. Repeat this several times while watching the power steering reservoir. Is the fluid bubbling? If so, good, you're purging air out of your system. In general, this is easier with the front wheels off the ground, but that is not absolutely necessary (if you have strong arms).
Once you have purged the system, put the cap back on the power steering reservoir, topping it off if the fluid level has dropped to the fill mark. Now, restart your car and observe the power steering pump. Does it seem to be operating quietly and smoothly? If you touch the pump 1-2 minutes after the engine has been running, is it hot to the touch? It will probably be warm, but _hot_ is an indication that something is overheating inside the pump. Is the power steering fluid very dark colored or does it smell burned? This is also a sign that the fluid should be changed ASAP and that some internal damage may have occurred. Burned fluid isn't necessarily an indication that your power steering pump is bad. However, if after changing your PS fluid the new fluid quickly becomes dark and starts smelling burned, then it's probably time to start saving money for a new or rebuilt power steering pump.
i would remove the power steering cap, and look inside of the pump, and take the end of a screwdriver, and dip it into the pump, and bring it out and look at the color of the fluid, if it is clear, then it has power steering fluid, if it has a reddish looking color, then it is atf + 4 fluid, also , you can look into the owners manual of your vehicle, if you have the manual.
bmw uses ATF as power steering fluid most likely one of the hoses are failing and will need to be replaced if u start to hear a buzzing noise when turning try not to drive vehicle that can burn out the pump but add fluid before you drive it again the resovor is a dark brown or black round canister with a black lid check the fluid in that if its low then you know its the power steering leak if not then it could be a trans. fluid leak if u have a automatic hope this helps you
YOU HAVE AIR IN THE POWER STEERING SYSTEM.YOU NEED TO BLEED POWER STEERING PUMP FIRST BEFORE DRIVING VECHICLE.CHECK POWER STEERING FLUID LEVEL ADD MORE POWER STEERING UNTIL REACH FULL COLD MARK..RAISE VECHICLE FRONT WHEELS OFF THE GROUND.START ENGINE LET IT IDLE WHILE TURNING STEERING WHEEL LEFT TO RIGHT NON STOP DONT LOCK OR STOP STEERING WHEEL KEEP TURNING IT SEVERAL TIMES CHECK POWER STEERING FLUID IF LOW ADD UNTIL YOU GET COLD MARK ON DIP STICK DONT OVER FILL POWER STEERING PUMP BLOW A SEAL.IF POWER STEERING FLUID LOOK TAN COLOR SYSTEM FULL OF AIR.TURN OFF IGNITION LET CAR SET FOR A WHILE CHECK FLUID LEVEL.IF STEERING WHEEL FEEL STIFF HARD TURNING DONT DRIVE CAR UNTIL YOU HAVE NORMAL STEERING.IF STILL HAVE AIR IN SYSTEM BLEED SYSTEM UNTIL AIR IS OUT.
YOU HAVE A RUPTURE PRESSURE LINE IF YOU HAVE NO POWER STEERING FLUID IN THE POWER STEERING RESERVOIR.LOCATE LEAK THEN BLEED POWER STEERING SYSTEM BY ADDING POWER STEERING TO RESERVOIR.DONT OVER FILL BY FULL COLD MARK ON POWER STEERING DIP STICK.ADD FLUID TO RESERVOIR WAIT A 2 MINUTES.CHECK FLUID LEVEL AGAIN.WHEN POWER STEERING FLUID LEVEL STOP DROPPING.START ENGINE LET IT RUN FOR 10 SECONDS.THEN TURN OFF ENGINE CHECK POWER STEERING FLUID ADD FLUID IF FLUID LEVEL DROPS. WHEN FLUID LEVEL STOP DROPPING.SAFELY RAISE SUPPORT VECHICLE FRONT WHEELS.START ENGINE.NOW TURN STEERING WHEEL GENTLY FROM STOP TO STOP MEANING LEFT TO RIGHT DONT HOLD IN POSITION.LET THE STOP TO STOP BE QUICK.CHECK POWER STEERING FLUID AFTER YOU HAVE TURN STEERING WHEEL ABOUT 7 STOP TO STOP.WHEN FLUID LEVEL STOP DROPPING YOU AT HOT MARK ON DIP STICK BLEEDING PROCESS COMPLETE.TURN OFF ENGINE LOWER VECHICLE BACK TO GROUND WAIT ABOUT 5 MINUTES CHECK YOUR FLUID LEVEL.IF FLUID LOOKS LIKE A TAN COLOR.YOUR POWER STEERING SYSTEM FULL OF AIR.TURN OFF VECHICLE LET VECHICLE SET A LONG WHILE TO AIR BUBBLES SETTLE DOWN LOOK FOR LEAKS AROUND POWER STEERING PUMP FRONT SEAL AND CHECK FOR LEAKS AROUND POWER STEERING LINES.
My 2006 highlander is starting to make a clicking noise when i turn the wheels in either direction. In looking at the fluid reservoir, it appears very dark in color. I'm guessing the fluid needs to be drained and replaced. Should that solve the problem or does it sound like a pump replacement?
drain all power steering fluid and replace with dextronIII/mercon transmission fluid start the vehicle and turn the wheel back and forth from lock to lock bouncing the wheel against the lock about 5 times on each turn for about 5 minutes
if this doesnt work you are probablygoing to need a new power steering pump
