    Default NS Rubbing sqeaking noise

    Hi all. Does any one know what could be causing this noise please? car is 1.9CDTi Z19DTH engine.

    The noise comes after about 5mins of driving 1st thing in the morning and will be there all day long. It is coming from the nearside of the car (not sure but possibly front side wheel area). Sounds like something that needs oiling (like two metals in close contact creating friction) and it's only audible above 10mph (it does not mean it's not there below that speed).

    It is more audible when making a right turn compared to left turn at speed above 10mph. The noise is there when driving only (none when stationary and engine running) and frequency increases as speed increases.

    It doesn't sound like drop links or springs as there is no knocking sound when it goes over bumps or potholes.

    I have checked the brake pads and there is still a lot of meat there but the discs could do with a change (nothing major though). Could this be the problem? Could this be CV gaiter?

    Any help will be appreciated.

    What you're looking for is a small piece of plate steel found on the hub.

    With the offending wheel off and the vehicle on axle stands, you are feeling on the inside face of the front disc... at the 6 o'clock position actually mounted on the hub assembly rather than the disc. It's a small, pressed steel 'stoneguard'. Get a meaty screwdriver between the guard and the disc and lever it away from the disc i.e. toward the engine. It'll barely move, but should be enough to let any stones drop out and stop contact with the disc.

    Best to do both sides. and you stop it sounding like a tank when you turn and move.

    I should add the size of the plate differs depending on the disc/caliper size. On my 314s it's tiny... on smaller discs it will be larger.

    Thanks buddy. I have bought new complete discs and pads for the front and rear anyway so all the discs will be coming off at the weekend and I should be able to see this steel plate on the hub much better. Cheers.

    That should make things far easier for you then.

    With the disc removed it's basically extending below the 'lump' of the hub assembly - might help others if you got a pic or two with the disc removed that would identify the position of the plate.

    As my 3.2 has 314mm discs the plate is roughly the size of your thumb, along the bottom of the hub... I think yours will be larger. Hopefully, this will be the cuse of the noise you're on about... in my case it sounded like metal grinding on metal, was worse when low speed manoeuvering and was downright embarrassing when parking at the pub with everyone staring.

    Here is a picture of the plate (arrowed) causing the noise. New front discs and pads fitted for now and the plate was pushed back.

    Car was taken for a test drive and the noise is gone. Thanks.

    Glad to hear it's sorted for you.... such a simple fix for such a horrendously expensive sounding problem.
