    Default My DS goes clunkclunk

    While driving (in first and second gears in my driveway), turning the steering wheel results in clunkclunk noises coming from near the wheels in a manner I would associate with bad CV joints. Is that likely, or do these cars have their own special song that means something else? It is definitely worse now than when she first went up on blocks a couple of months ago, and has not been driven on the road since.

    Cheers,
    Melanie

    It's grease those driveshafts time. One grease gun and a guru can chime in on the appropriate goob.

    As forumnoreason says, but don't go mad with the grease gun. One or maybe two pumps is enough, any more and it will get flung all over the engine bay. Go on, ask me how I know

    Any degreasing or washing down of mechanical components whilst up on blocks? The comments are likely right, but....
    If, as you say, the car has been up on blocks, it's reasonable to assume things could have been released, even if they weren't the job at hand. It's pretty easy to take a phone call and come back to the car and forget to have tightened a couple of nuts. If the steering rack has been released, you would likely get a "clunk clunk". If the turning headlight mechanism has been put back incorrectly.... "clunk clunk". Grease is you friend ( in small quantities, as already stated ), and it always quietens things down, but it would be good to inspect and identify more accurately where the noise is coming from, even a degreased anti roll bar spring can give you a clunk clunk sound, just depends on what has been going on. The good thing is that a clunk clunk, should be relatively easy to narrow down to a particular component.

    I would bet the left drive shaft is suffering from not being lubricated, but as Michael says it could come from a range of things! My claim is based on personal experience and on it being a common issue and prevalent mainly in the left shaft, do a circle at low speed on hard left turn and see if it is clunkclunk clunking rapidly, then try in other direction. If it is not clunking to the right that might narrow it down. The grease nipples are on the end of the shaft tyre end, worth going around and giving the other greasing points a touch as well, the hubs have one on top and bottom.

    Thanks for your advice, tonight we did a general engine degrease + fresh grease. I noticed clunking still happening on both sides after the 30km return drive.

    Judging from what I saw come out of the engine bay tonight after a wash, I wouldn't be surprised if the same kind of overgreasing happened to my car in the past, too! Anyway, tell me how you know?

    Does the steering feel ok? Is there play in the steering idlers or the track rods?

    The clunking is only when turning more than 90 degrees. It's not loud - Paul didn't notice it as much as I did. I think it does increase in speed with the car's speed. The steering seems okay to me, although there is some play in the wheel that I took to be "normal" in these cars - I don't have anything to compare it with!

    If the sound rate changes with vehicle speed then it is more than likely the tri-ax hubs that at least need greasing or they have worn to the point where they need a refurbish.

    Hi All,

    The grease nipple in a DS driveshaft only lubricates the spigot that sits between the two outer universal joints. Late DS drive shafts are double universal on the outer, and triaxe inner. The outer universals are not grease-able.

    The triaxe was the one that generally wears first, and is available a a seperate part to replace. The outer uni's do wear out, as does the centre spigot, but are known to give a long life. The replacement for this outer section of the shaft is now a constant velocity joint, as its for easier to manufacture.

    Citroen sold this type of constant velocity driveshaft as a replacement shaft for both the SM & the DS driveshaft after production of the cars finished.

    best regards,

    Greg

    Knock knock? This is no joke...as I posted on my CV joint thread, after much palavering took place, a garage undertook to remove the drive shafts and have them sent off for rebuilding, but they were so badly worn that they couldn't be. At least I can be fairly certain - maybe (See what I did there?) - that they were the source of the running knock-knock jokes coming from left and right. Is it possible that I will one day have a drivable classic that hasn't cost me my sanity?

    Did not the car come from South Australia? That alone is a caveat.

    Default clang clang

    persevere, it is worth it.

    i had a clang clang yesterday

    a hubcap detached on a speed hump - clang clang

    rear wheel

    it disappeared completely

    spent fifteen minutes searching the gutters and bushes for my precious Pallas hubcap

    gave up, drove off .... terrible clang clang noise returned

    instead of rolling along the road next to me it turned out that the hubcap went up into the cavity of the rear guard and lodged there

    so - bonnet up, tools out, rear guard bolt undone, hubcap retrieved and smacked back on, guard back, tools stowed, off we went......

    sigh

    That's a good story, glad you had a happy ending! Lucky those rear guards are a cinch to remove, eh?

    Does the car shimmy at speed like an out of balance wheel as the speed increases I'm wondering if it doesn't have cracked suspension tubes that you can hear moving around.

    Are you sure it's not a rollbar rattling away I re-assembled one ( I assume incorreclty) years ago, and it rattled like a normal car with flogged out rollbar bushes.

    I just installed new drive shafts. Ordered them from Citroen Classics in the U.K. If you are doing just the driveshafts, it is a straightforward job, as both the new and the old can be slid in and out through the hub. No need to take wings and brakes off etc.

    If on the other hand (as I have just done) you are doing brake discs as well, that is another story altogether!

    No Shane, I don't think this was happening, it drove fine at speed. It seemed like a classic case of worn CV joints by the time I got it to the garage.
