    Default Clunk in front left somewhere

    Hi everybody

    i have done a bit of reading and seems like others have had clunks in the front end and usually itís the bottom arm bushes.

    I am getting a knock which is most noticeable when taking off or coming to a stop. Itís just a single clunk. I would award it was the gearbox month but itís perfect. Have had mechanics look over it and they canít see anything. Iíve replaced all front bushes except for sway bar but they are fine. I have new shocks as well as new discs and pads. Other engine mounts are fine. CV joints feel ok there is no knocking when cornering. I have also replaced the exhaust coupling at the exhaust manifold as that was knacked. Still no good. The car has done close to 400,000ks so going well but this is very very annoying. Anyone have any other ideas???

    What model is it?

    FWD cars have 3 engine mounts to take the torque reaction from the wheels - don't forget the bottom one near the drive shafts.

    If it's high up, I'd take a look at the bearing at the top of the McPherson strut. They thunk when worn and the horizontal load changes direction at start and stop.

    I'm guessing engine mount too... Depends on what car though!

    Your symptoms sound a bit like an issue I am about to fix. If you can reveal what it is that you drive there is a chance of moving forward.

    Cheers

    I just looked at his past posts and he has a:

    "306 sedan XT with the 2litre twin cam 16v 2000 model. It's been a great family car and coming up on 380,000k's. Still goes really well".

    You can't tell by looking to evaluate the swaybar links. Once you pull them out you can see if they are not tight. Any slop will cause nasty clunks. I've just replaced both sides on my 406HDI and I also did the lower balljoint on the driver's side. That is also hard to diagnose as you need to get a jemmy bar in the right spot while it's on a hoist before you can see movement. Best diagnosed at a Pug repair shop. Coles in Lismore diagnosed mine. They are superb at finding stuff that is not easy for the home guy. Now I have No more clunks.

    Hi thanks for that yeah lower arms are all brand new. I haven’t done drop links will pull off again and check but they feel ok. Only things then I guess are engine mounts? They look fine and with pry bar and rocking engine still look ok. Maybe worth just changing them anyway?

    Some have reported the driver's side upper engine mount tearing out of the body on the 2 litres. But I assume you mean left side of the car as you sit in it rather than left as you're looking at the engine?

    Could be loose mounting bolts but unlikely. Depending on caliper Style sometimes slide pins become worn and the caliper will clunk when braking and possibly when taking off. Worth a look if you have checked everything else.

    Droplinks 9 times out of 10

    even if they 'feel ok' there can be wear in them.

    There cheap and easy to replace. 5 minutes per side

    Ok so I have changed the drop links. The old ones felt fine but bought new ones so changed anyway. Still not fixed!!!
    could it be CV joint maybe? There is a bit of play when in gear and rock wheel back and forth but not a clunk like my sound? I’m really at a loss on this one.
    Brake caliper has a tiny bit of movement on sliding bolt but don’t think it’s that. Any other ideas??

    Ok. 306, high mileage, not drop links. That only leaves the bushes on the bottom wishbone/control arm, and the top strut bearing. Check that one. I have seen them shot at 50,000 km.

    I didn’t change them when I replaced the strut so I will look at them. Wouldn’t you see the strut move if it was gone though?

    My money sez it's the callipers. It may not feel like there's much play but they don't need much to clunk like that. Have someone in the car apply the brakes with the car on jacks or stands, grab the wheel and try to turn. You'll see what's what then.

    Or stop the car right next to an assistant with good ears. They should be able to tell if the clunk comes from the top of the strut or somewhere lower, like the calliper.

    I will get my wife to drive it and stop etc and I will listen. I really think it’s the gearbox mount but it looks good and can’t get it to hit using pry bar! Will see if I am hear where it come from. Will let you all know what I find

    Good luck with that. Sometimes you can tell exactly where noises are coming from, sometimes they travel around and appear to be coming from other places. A very experienced Pug mechanic told me this on at least two occasions when I was tracking down noises.
    He had a couple of amazing stories of experiences to illustrate this but I can't remember them.

    You'd think that the pry bar would reveal movement....that's what they use in garages. And I have been told by a couple of garages using this method that certain bushes were worn out when they were worn but still serviceable.

    Good idea though to have your wife drive, but whilst you contort around upside down in the back seat with legs flailing I hope nobody thinks you are being kidnapped.

    Perhaps my point was not clear enough. The person listening tp the noise needs to be outside the car, that is why I said:
