The 'foaming' you describe is almost certainly air getting into the system. The power steering pump will cause a suction effect in the pump and then pressurise the system. Look for loose hose clips, damaged piping, and leaking seals on the pump body between the pump and its fluid reservoir.

Power steering fluids, like most, vary in color. Personally, mine is clear. Brown sounds like an unusual color to manufacture, but a very deep reservoir of clear or slightly dirty fluid might look brown. Or, they might have mixed two different brands of fluid, for example if it was topped off at an oil change. Try sticking a clean rod into the reservoir. ...

Part number 89020661 has now been replaced by 89021182. The description of the newer fluid is (from Amazon.com - same in other places): Amber-colored, light-bodied mineral oil Contains a specially developed additive Anti-corrosive and non foaming Formulated for automotive use For use in vehicles with regular hydraulic power steering systems Typically, ...

The answer to this question is NO. It is not bad. It's just harder to steer. But that's how people used to drive for many decades before the advent of power steering. Do, however, make sure that your power steering pump is mounted properly onto the engine block and the serpentine belt because the belt has to have all the pulleys mounted on and tight.

Yes, a lot of power steering pumps call for automatic transmission fluid (ATF) instead of traditional power steering fluid. The difference between the two fluids will vary between brands, but has to do with a difference in cleaning, lubricating and hydraulic characteristics. Often if the wrong type is used, the fluid will eat the seals in the power steering ...

With power steering complaints such as yours where the symptom is intermittent the diagnosis is mostly guesswork in a setting such as this. You can do a few things to get to the source though. A little about modern power steering Many vehicles have power steering assist controls such as a vehicle speed sensors and pressure switches/solenoids that stage the ...

tl;dr: Steering feedback means different things to different people. Ultimately, however, it's about using the steering wheel as both an input and an output device. At a very high level, the concept of steering feedback has to do with the user interface of the car. If we restrict the discussion to just the wheel in front of you, it's easy to imagine that ...

What's the difference between the two in terms of how they work? In both cases, the power steering simply adds some force to the steering when it detects the driver is trying to turn the wheels. Simply, in one case there is an electric motor to add this force, while in the other hydraulic liquid is used. Is one more efficient at steering than the ...

Drive by wire systems have no mechanical connection between the input decive (like a throttle/gas pedal) and the output device (like the engine). They use only electrical signals. To my knowledge there aren't any cars that use this system for steering. Your steering wheel is mechanically connected to the front wheels but is assisted by an electric motor. ...

There's a chance that the belt may be slipping when you hit the puddle...and as a result you may be losing feedback. How long are you without power steering?

You can damage power steering pump when driving without having fluid in it, if it´s leaking just check it every few miles and you are ok, when there is fluid, it has to work, it´s just leaking right?

You seem to be describing the weight of the steering, which varies from vehicle to vehicle. It isn't something to be concerned about. Many factors influence the lightness (or heaviness) of steering feel, including: steering/chassis geometry amount of hydraulic (power-steering) assist tire size I would be concerned if you cannot or struggle to turn ...

Quoting the factory service manual for a 2005 Jeep Wrangler (Page 0-6): POWER STEERING FLUID The recommended fluid for power steering system is Mopar ATF+4. Mopar ATF+4, when new is red in color. The ATF+4 is dyed red so it can be identified from other fluids used in the vehicle such as engine oil or antifreeze. The red color is not permanent and is ...

A lot of BMWs have a noise, but it might be a pump going bad. If I remember right, the lines are right under the reservoir. Check them for softness, and if they are soft/chewy I guess you can replace them. If it's a pump, run until it pops, as they are like $400. As far as the lines from the rack, those are hard lines, and unless clearly pinched not sure if ...

Is the noise coming from the steering itself, or from the tyres? i.e does it make the noise as you are turning the steering wheel, or does it still do it as you hold the wheel steady during the turn? If it is the latter (the "hollywood tyre squeal" effect), that is quite common, particularly on the smooth concrete you tend to find in multi-story car parks. ...

As a general rule, high pressure hoses will have crimped connections on them. The small clamp connectors are on the pump feed and return hoses, which are low pressure lines. They typically don't leak as often as the high pressure ones do. The high pressure line, according to the diagram you posted, comes from the PS pump and enters the rack. There is a ...

If replacing the power steering pump triggers a fault code, all you need is one of these to reset it: http://www.amazon.com/Autel-MaxiScan-MS509-Scanner-vehicles/dp/B0056VHZD8/ref=sr_1_2?s=automotive&ie=UTF8&qid=1355944663&sr=1-2&keywords=EOBD+reader Someone can feel free to come along and prove me wrong here because I'm not 100% sure how ...

Not knowing the exact state of the power steering fluid in the first place, I would be hard pressed to tell you it was a scam. I'm sure they performed the service for which you paid, so at least that portion of it is not a scam. With that said, you and everyone else should know, this is a typical way that places like Jiffy Lube (or other quick oil change ...

This is called "cramping" the steering and it is bad for the pump and for the steering rack. What you are doing is forcing the system to try and push the steering components further than what they are meant to go. This causes over pressure on the pump (you may hear a slight squeal sound of the belt as the pump momentarily stalls), and it creates a bind in ...

tl;dr: Winter tires are different and you are sensitive enough to tell. It doesn't sound like you have a problem. It seems that you are detecting exactly what I detect when I put my winter tires on after the summer. Quoting from the Tire Rack article: New winter tires begin with deeper tread depths and more open tread designs than the tires used ...

Based upon the information you've provided I can think of two things that may create the "medium frequency whirring" sound. 1. Low Power Steering Fluid When your power steering fluid is low the fluid cannot absorb sound and what you hear is the pump possibly going bad as a result. Sometimes, when the fluid is just low there will be audible component ...

I'm unsure if it would actually pinpoint a leaking fitting/seal. Using a hand vacuum pump with a reservoir you fill the system and apply ~20inHg. Repeat until you stop seeing fluid entering the reservoir. Leave the vacuum on the system and walk away for 5 or so minutes. If pressure doesn't drop you're good. Generally if you don't see a fluid leak, look at ...

A - You can replace the seals in the pump if your pump is leaking. I've never done this on a Subaru, but this link should help: http://www.ultimatesubaru.org/forum/showthread.php?t=123004 B - I checked at my local Subaru dealer and their price for parts only would be $370 plus tax. Maybe your dealer was including installation? C - As far as the reliability ...

I had this same problem. You need a replacement orange O-ring with part 91345-RDA-A01. This video will show you the problem in great detail: http://www.youtube.com/watch?v=Wf-_qp1y4yc BTW, if you have a V6, there is a recall on a possible leak in one of the power steering hoses. You may want to have that checked out as well.

One car of mine has red, the other is yellowy-clear. More important than the color is the smell. If it smells burnt, that could be an indication of a problem.

My power-steering pump failed about 2 months after the noise you described. I'm in an E46 3 Series. The noise would be louder when turning at a slower speed than it would at a higher speed. Dealer labour and part came to $1600 CAD, warranty saved me there.

The BMW power steering reservoir's usually say "ATF Only" on the caps as well.

Make sure the power steering pump has fluid in it. If it runs dry it can cause your pulley to seize and your belt to break.


4

Yes and quickly. Get the problem fixed or it is going to be real, real expensive to replace the pump and maybe the lines plus the power steering rack when the seals, etc. wear out due to lack of lubrication plus it must be a bitch to drive with no Power steering!

So, do power steering hoses just leak randomly like they are claiming? Or is there a reason to be suspicious? I will bet the problem lies with the nylon seal which needs to be replaced with the pump (it's a real PITB to install) and they didn't do it with the pump install. It's the seal which allows movement out of the high pressure side (out flow of fluid)...
