Foaming power steering fluid


Sounds like a bad replacement rack.. Did you buy a rebuilt rack? Look up the number for A1 Cardone.. They are in my openion the best rebuilders of rack and pinion.. You can talk to their tech team and they can answer your question.. I have never seen this problem.. i have had racks that the internal valves have went bad and lock up the rack and pump.. Post a comment here and let us know what you find so we will know too.

Power steering fluid leak on my 2000 ford explorer


Most likely the seals on either the pump or the rack and pinion. Could be a leaking hose between the two. Might be a loose or leaking hose connection at the pump or at the rack and pinion. If you lose the fluid in a short period of time it shouldn't be to hard to find the leak, and you are also smelling it burn when it hits the the exhaust pipes. Refill the system and with the engine running have someone turn the steering wheel back and forth while you look at the pump, lines, and at each end of the rack and pinion. you WILL find the leak.

Rack and pinion vibrate badly after installation. starts to vibrate (back and forth motion of the steering wheel of approx 2 inches each way) after trying to move the steering wheel.


The rack is incorrectly installed in the chassis of the truck and its position isn't fixed - it shifts around the securing bolts. The vibration is caused by the pressure of the servo pump and the movement of the pinion: when the rack moves even by a little fraction by itself but the steering wheel doesn't follow it accordingly then the pinion is forced to rotate a tiny bit more than it should and that is enough to open the valves of the servo and the oil pressure presses on the rack moving it all the way to one side with force. When the movement stops because the rack has nowhere to go no more the pinion stops and the valve close, the oil pressure drops, the force on the rack drops and it tends to go back to its original position. That opens the valves again, but in the opposite direction so the rack is slammed on the opposite side. The process continues as long as the steering wheel is turned , generating that vibration.
This is a very dangerous situation, the car is not safe to be driven on any distance, at any speed. Tow it to a repair shop and have the steering mechanism in its entirety inspected, most likely it will be necessary to replace it completely.

Hi i drive a ford escort 1997 16v 1800. My steering is verry loos on the road i can berly keep it straight and when it is straight it pulls to the left side and back almost like the suspension is dropping...


  1. Wheel mounts to shaft. (does not typically wear)
    2. Shaft has a joint I think. (does not typically wear)
    3. Shaft knuckle attaches to steering rack. (does not typically wear)

    The following components do wear.

    4. Pinion gear connects to rack.
    5. Inner tie-rods connect to rack.
    6. Inner tie-rods connect to outer tie-rods.

    Sitting still, engine off, you should be able to jiggle the wheel back and forth. Depending on the sound, point at which I feel contact through the wheel, I can usually tell which component is worn.

    Many years ago I had replaced a rack & pinion when a mechanic had diagnosed it as the source for a knocking noise. My steering was much tighter post replacement.

    But the most common wear item in the steering system are the outer tie-rods ends. I don't think too many inner tie-rods wear, but it definitely happens as well. My case may have been more unusual or people just ignore it since it isn't a safety issue; don't know.

    It's also possible for certain suspension components to create noise, but should be ignored as a potential cause until the obvious and more likely steering components are eliminated. Intuit, Oct 1, 2012

    Messages: 8,404 Likes Received: Trophy Points: 363 Location: south TX or northern VA Pinion Mount Bushings, between the rack housing and the firewall, that have gotten chewed up from age or have worked their way out sideways from under the two clamping brackets. The effect is as if there was another driver steering slightly after you move the steering wheel.
    If you have someone work the steering wheel back and forth, while you look behind the enginedown at the lower part of the firewall, you may see the steering rack and pinion moving back and forth noticeably.

    You can buy the bushings in auto parts places, at least www.carquest.com shows them. If you type 'rack and pinion mount bushings' into the search window at a carquest website, then click on the link of that name - and keep sliding down the rather long page to see the images. They have carquest part numbers like 577-7045 (right) & 577-7046 (left), or KB0367 for the pair; about $6 each.

    Installing them is straight forward, though maybe not easy. You have to work from underneath upward, with a 14mm deep socket: And the 4 nuts holding the two clamping brackets in place may be stiff from corrosion. With both of the ones I had to replace, it took me a lot of effort to work the nuts free, squirting penetrating oil up and working them a quarter of a turn back and forth at a time until they freed up. I used a 6 point socket so I wouldnt be damaging the nuts). Then I pried the rack slightly forward to slide the old bushings out and the new ones in.
    When done, the steering no longer had that mushy feeling.

    The other things intuit mentioned are also worth checking - since the steering components seldom wear out one at a time.

    Messages: 241 Likes Received: Trophy Points: 76 Location: USA U joint between the rack and the column and then wiggle the wheel back and forth to see if they both move uniformly. If they do, be happy and go on to checking the outer tie rod endsand the lower ball joints. I had been through this before with my sedan, so after the "grab and wiggle" I just ordered both outer tie rod ends and both ball joints and did them all at once. Problem solved.

    My outer tie rods were so bad I could hold one in my hand and move(not pivot but actually move the whole thing) the stud and ball back and forth with 2 fingers so much it scared me to know It'd been driven with them installed. It's amazing how bad they can get, and people don't understand so they just keep driving it.

I have already changed the belt and the tensioner and again the power steering stopped working the power steering fluid good i was wondering what is wrong now


1st make sure your power steering belt is stiil on@ tight. if so i would suspect a bad steering rack @ pinion. do you hear cracking or popping when you turn the wheel? is there any fluid leaking from under the steering rack under front of car?the steering pump may be air locked, keep turning the wheel back @ forth to see if it loosens up any at all.hope this helps!!
