    Steering got harder all of a sudden on my way home and when I arrived I
    found fluid leaking from the under carriage around where the steering shaft
    connects to the Rack. there was little fluid in the reservoir.
    Any ideas on what to do appreciated, assume a "how to" for dummies
    instruction style.
    Does this mean the rack is broken?
    Seems brickboard says could be a hose or seal? not clear.
    Is this easy DIY type or should I go to mechanic?
    Is it OK to put in some ATF for now till I fix it/ get it fixed?

    Thanks for your help.

  2. From a point at sea, to the circles of your mind, this is PT:
    You need to find where it is leaking from. Hopefully it is just a
    split pipe. If it is the pipe from reservoir to pump you may get away
    with taping it up as a temorary measure. If it is a pipe from pump to
    rack, these run under pressure, so putting more ATF in is a lost

    However, if it is coming out from the rubber bellows where the
    track/tie rod joins the rack housing, then it is probably not good
    news. Have a close look at them, including the *top* of the bellows,
    in between the folds - is there a hole?

    The thing is that the fluid should never get as far as the bellows,
    there being seals inside the rack to stop this. If the bellows start
    to fill with fluid it means that the seals have gone. Now the bellows
    can cope with a small amount of seepage, but eventually they start to
    sag under the weight. When this happens, the top of the bellows starts
    to snag on the linkage inside, and eventually gets pinched and
    ruptured by it. From here on fluid just gets squirted out every time
    you turn the wheel.

    I've had this happen on a couple of cars, and simply replacing the
    bellows is only a temporary fix. It is possible to replace the seals
    in the rack, and I've done this successfully, but finding the parts
    for it was difficult. Eventually I got some from a rack rebuilder who
    grudgingly sold me some.

    The simplest answer is an exchange rack, which should be good for
    another 331k Km. They are pretty straight forward to fit if you are
    doing it yourself, though it can be messy (it's still full of oil even
    when it's empty) and you'll have to get the tracking set afterwards.

    If the hole is in the bellows you *may* get some mileage by topping
    up, but expect to lose lots and not be popular with other road users.
    The power steering is failsafe - if the power assistance fails you
    still have steering, but it will be very heavy and low speed stuff
    will be difficult. If you go too far without oil you risk losing the
    pump too, and these cost as much as the rack.

    Hi all,
    I Had a closer look this morning and found the source of the leak, It comes
    from one of the metal pipes ( 2 short and bent pipes) directly under the
    joint (where steering column/shaft meets the rack). they were flaking apart
    when I touched them but only one is leaking.
    no liquid in the bellows (both sides).
    Any common name for this? I need to get new replacements since there are
    unlikely and impractical to buy used ( corrosion and all.)

    All help appreciated.

    Excellent and a good Laugh with that, a friend put me in contact with a
    retired mechanic today and he was glad to come have a look. He said he would
    get some pipes from a salvage he knows well and have it done tonight ( still
    not back though). I can learn from him this time. I am assured it will be a
    very friendly charge $$. got a digital pic of the spot but could not send it
    to your email...

    Cheers and Thanks again.
