    Mostly to HT, but open to anyone who's got insight...

    My wife's 04 Sonata has recently begun groaning with any (even the
    slightest) turn of the steering wheel. Seems to clearly be coming from the
    rack. PS fluid level is up to where it should be, but that's really all
    I've had to look at. The word groaning might not properly describe the
    sound. It really sounds like really, really dry bearings rubbing when you
    turn the wheel at all. It does clearly seem to emanate from the rack
    though.

    Hoping to get the time to look at it further tomorrow night, but open to
    any experiences that may be out there.

    Not much to offer without hearing the noise. Could be a dry ball
    joint or tie rod end.

    Yeah - it's always hard to offer something without seeing/hearing the
    problem at hand. My post was a quick shot in the dark, before heading out
    of town for the day, for work. I hope to be able to look at the car
    today/tonight - we'll see how things go during the day. Doubtful it's a
    ball joint or tie rod end - it makes the noise as soon as you touch the
    steering wheel to apply pressure in either direction. It persists as long
    as you hold steering pressure on the wheel. First glance makes it appear to
    be a rack, but that is very premature.

    If it's pump noise, suck the fluid out of the reservoir and look at
    the screen in the bottom. If the screen is filled with crud, fill the
    reservoir.

    Thought I'd leave the entire thread intact for the archival value, since
    there is some troubleshooting thought process contained with in it, and post
    the final resolution.

    I finally got the chance to take a look at the car on Saturday. The
    grinding noise was immediate, with any steering wheel input, in either
    direction. It was not however, constant as I had originally posted. It
    only presented with steering wheel input. The noise did emanate throughout
    the entire front end of the car though - was not localized to either side,
    or to any single component.

    Taking the easiest approach first, I shot some grease into the RF tie rod
    boot via a grease needle. Instant success.

    I thought there was a reasonable chance that greasing the end might fix
    things, but at the same time I held a certain reserve. The noise was very
    loud and much more forceful than I would have expected from a dry joint. It
    did not start out with a little creak while a small amount of steering wheel
    was applied, it went full groan. Really lead me to initially think it had
    to be a rack problem.

    I am holding a reserve thought though, and won't really pronounce this car
    fixed for a few days. Jacking a car up like this tweaks the front end
    geometry. It is possible that another element of the front end (which is
    probably suffering a dry condition), got tweaked a bit while jacking the
    car, and that is really what relieved the binding. If this is the case, the
    noise may likely return. Clever me - I intentionally did not grease the
    entire front end yet, because I want to see if the noise does return and try
    to isolate it, if it does. I have to get under the car soon and service the
    tranny and do an oil change anyway, so if there is no recurrence of the
    noise, I guess we'll pronounce the situation healed and finish lubing up
    things underneath. Boy - I sure wish there were still zerk fittings on
    critical joints...
