    Clicking Ticking Knocking noise when turning wheel L & R - Steering Box?

    Hi All,

    I have a 1993 200tdi D1. When I am stationary, or moving, and turn the wheel left or right, I hear a defined single clicking/ticking/knocking sound (I wouldnt call it a popping noise). This sound occurs every time the wheel is rotated approximately 90 degrees, left or right. It has been happening for a while (year+), however seems to be more prominent now and I can get it to occur with constant repetition.

    I have tried to isolate where the sound is coming from, and it seems to be the steering box itself, however these things can be deceiving and sounds/vibrations can of course travel through the whole steering/suspension system.

    I have checked the track rod and drag link tie rod ends. I actually replaced them with Lemforder joints a couple years ago. They 'seem' fine.
    I have heard the panhard rod bushings may play a part. I have inspected these, and the tightness of the bolts, and it 'seems' ok. I have even lubricated with silicon spray to see if the noise changes but it is still as prominent.

    I have a new Bilstein Steering damper (the sound was occurring before this anyway). I released the damper just to check if it was involved in the noise in any way, and it did not change a thing.

    The steering column appears fine with no loose play or knocking against anything.

    It really feels like the noise is coming from inside the steering box.
    As it happens when the car is off, I'm assuming it isn't related to power steering fluid (which is full in the reservoir anyway), or air in the system...


    I'm planning to drive 800km return over the weekend. As this noise has been happening for a while Im not overly concerned, however keen to get to the bottom of it.

    Does anyone have any suggestions, things to look for specifically, or information on anything I can do to the steering box to check?

    Thank you.

    The most common reason is that one of the UJs in the steering column has failed. it may seem OK with a simple on vehicle check , but take it off and check the UJs for looseness or tightness.

    Caused by doing too much "circle work"?

    Thank you. I did my front uni joints 3 years ago now (time flies). Assuming they are ok is probably not good enough. I will look into these.

    can you hear the noise from inside the car(eg. while driving or whatever) or from the outside(eg. more so from underneath at the front, or from above)?

    Will make a big difference.

    I've been doing some detail work on my D1 recently.
    One major annoyance was a knock sound and coming through the steering column. The upper uni joint on the intermediate shaft had the smallest, like 0.1mm, of play in a certain position, otherwise felt good. stg box uni joint felt good. in moving the intermediate shaft up/down/sideways, I can hear the knock too. seemed to be from the firewall!

    Anyhow, changed the intermediate shaft, no difference.

    I'm trying to do some prep stuff on the car, as I plan to sell it soon. One thing I've had on the car since I bought it is a 'sports steering wheel'. Started the work to remove it and replace the original wheel back, and wouldn't you know .... the damn steering wheel nut was loose!. Tightened it up went for a quick spin, knock sound now gone ... of course.

    My apologies - I immediately thought UJ on the front propshaft (which I replaced)
    I have not done the UJ on the steering column. It looked ok during the on vehicle inspection (like you say)... however, quite possibly a culprit.

    Thank you. That is a semi simple one that I will investigate.

    I can definitely hear the noise in the car, with it on, or off.
    I will definitely remove the column and inspect the UJs, both upper and lower... even though they seem ok in situ.
    Interesting to hear about the steering wheel. I have the standard wheel, but have had it off (painfully) a couple times. Maybe its worth taking it off again and ensuring it is reseated and tightened properly.

    Yeah, check the steering wheel for sure. Even tho the nut was loose on mine, the wheel was still very tight on the splines.

    My method for pull stg wheels off is to bang on the rim like a crazy thrash metal drummer(with fists, not drum sticks!! ).
    What this does is to help loosen the grip of the splines. bang it for about 10sec at a time, check if its loosening, bang again, check again.

    Don't try to just heave it outwards.

    if you do take the wheel off, also check the indicator cancelling mechanism for clicking. Sometimes they can make a click noise(I've had a few). A light dab of grease on the cam that pushes the cancel mechanism ca work a treat.


    I have a Peugeot 307, and it made diabolical clicking noises on turning. Brother was driving it for a bit, and he changed out the sometimes touchy headlight switch(would randomly turn itself off). Turned out wasn't the problem, but when he put it all together again, it started this maddening clicking-clucking noise. I'm too lazy to do the hard stuff first and pull it all apart, so sprayed with lithium grease .. was the only lube I had with a straw ... helped for a bit, but came back. gave it another spray ... so far it's been ok.

    But this noise was a 100% for sure plasticky clicky/clacky sound. Couldn't mistake it for a metallic click sound.

    Well, I just replaced the entire steering column with new UJs and still have the clicking noise.
    Its definitely a metallic clicking noise, and still appears to be coming from the steering box.
    Its quite loud, and very sharp.


    Other than these boxes leaking, what are symptoms of failure? Are they in anyway serviceable, or easily inspectable?

    Yeah, the most common leaks are from the bottom seal.

    Mike from BritRest has a few he does up. Just the other day he got a cheapie Chinese box in to open up and have a look into.
    He's in Canada, so LHD, and LHD boxes are getting hard to find now.

    Brittanica Restorations on youtube

    That link is to his Youtube channel. Look for a couple of vids about stg boxes, one labelled Chinese boxes and the other something about microscope, two vids in the last 7 days or so. he explains a lot of their inner workings. could be a bearing or something.

    But a though just occurred to me about your click at about 90° turn. The oil cooler pipes can come a bit close to the intermediate shaft right where the slider section is. you have one lower uni joint, one upper uni joint(not replaceable) and then you have the sliding joint. All three have a bolt to to keep the connections tight. just make sure that the oil cooler pipes aren't too close to the sliding joint ... for example that whilst the steering is straight, there may be enough clearance, but when you turn, the shaft is wider at the sliding joint section, and possibly clipping the oil cooler line as it's turned .. or something like that.
