    Groaning sound while turning?

    My Disco has started to maka a groaning (light grinding?) sound while spinning the wheel quickly. I have had a peek underneath and it doesn't look like anything is rubbing which was my original theory.
    Im starting to think that the steering arm joints may be worn and need to be replaced. Is that likely to be the problem? Could it be something obvious that im missing?
    The steering box was replaced about 20,000 ks ago so it should be alright. Is there anything i can do to test it?

    Thanks heaps,
    Dizza

    Does it sound like it's higher up? My steering column grinds when turning, but it's the column somewhere in the cabin rather than under bonnet.

    Mines been doing that for years! Have replaced ball joints (due to cracked rubbers) but did not make any difference! I thought is was normal at low/crawl speeds. Interested to see other's thoughts!

    It does sound as if it comes from somewhere in the cabin. Perhaps a bearing as the shaft goes through the firewall?
    Are there any bearings in the steering assembly within the cab? or are they bushings or something? And if so are they greasable?
    Mainly because the dang noise is annoying as long as it isnt doing damage over time imn not worried.

    Oh and im running bog stock sized tires

    From here:

    Land Rover Addict Forums

    "With the 300tdi Def and i believe same for the Disco LR did bring out a mod kit to replace some of the PAS pipes due to resonance in the pipes creating a 'groaning' noise. i had this done under warranty on the tdi and it worked. TD5 still groans though, when not held on lock its acroos the range has done since new, i just live with it now.

    hope this helps "
    .................................................. .................................................. .....
    Mine also does it, and has done since I got it at 50,000km. It got a new PAS pump under warranty (recall) and continued to groan throughout.

    Yep mine does it too I have replaced ball joints due to split rubbers thinking that this may be the issue. There was no change to the noise which I agree is more of a resonance sound rather than metal on metal. In my case it seems to occur when the car is cold, doesn't happen as much when warmed up.Its not that loud and probably not noticeable to passengers . I did try some power steering " conditioner" additive as this worked for a similar issue on a commodore a few years ago but didn't seem to make any difference on the LR. After reading the other comments I don't think I will worry too much about it.

    The steering shaft has a rubber boot around it at the firewall to prevent the ingress of fumes and water etc. This boot gets dry, then makes this groaning sound, much louder than you think it should for something so minimal. A quick but not permanent fix is just to grease the shaft under the boot, spray WD 40 or whatever, if the noise goes away you have at least found your problem. You can slide a blunt screwdriver or something similar from the engine bay side to open up gap to allow some grease or spray to be applied. And this does last for a short while too. The permanent fix is something I believe was introduced later by Land Rover - slide a close fitting PVC pipe sleeve onto the shaft and under the boot. The close fitting sleeve should be cut vertically, along the length, so the boot can grip it while still providing a seal, plenty of grease between the shaft and sleeve. I did this with mine when I had the PS box out for new seals, hasn't made a noise since (and it was annoying). I measured the shaft, then went to bunnings and bought a piece of PVC pipe so the actual cost of the fix was very small. I used white pipe, but I think the black irrigation pipe would be easier to cut and compress to fit under the boot, its a lot thinner and more flexible - still cheap. The job can be done without removing the PS box, just need to slide the universal joints out of the way to remove the top of that section.

    Have a look at this thread too for some other input:
