    Default Friction damper

    When removing the front shockies it exposed the friction damper.
    Should I just leave it as is or lubricate it. If so, with what.

    I suspect lubricating it may remove the "friction" .

    Doubtless, Citroen experts will tell the correct procedure.

    Hi Winkbul45
    What friction damper is that ??? I was not aware they had one fitted. They have an unusual double spring arrangement that may be various types depending on the model. Is it a flat wire concentric spring you can see ?

    Friction dampers were fitted on the front suspension up until 1975, but it's not possible to fit hydraulic dampers to that setup without surgery/bodgery.

    What size were the bolts attaching the damper mounting plates to the front arms?
    Friction damper type would have been 7mm thread/11mm A/F spanner and would usually be hidden underneath a rubber cover which protects the setup from the elements.
    The mounting plate for hydraulic dampers would use 9mm bolts/14mm A/F, with more substantial 'stubs' on the radius arms, hence the element of bodgery to retrofit later damping on a pre'75 vehicle.
    As Robmac has advised, grease or oil on a friction damper assembly is 'game over'...

    I got the name wrong. It was the suspension arm, sorry!

    Hi If your asking what to do about the bearings. They are usually very reliable. If there is no sign of wear, if theres no grinding sounds when you rotate the arm, if there is no sideways movement at all then Id leave the bearings.

    Hi,
    Thanks for the clarification. Those are the suspension arm bearings and should be greased and set up when put together or rebuilt. So as Ian said just leave them if no problems are showing.
    Do you have a manual for your 2CV. You can down load some from the web which may help you. But I always buy a paper manual myself for all my cars. As it is good to see what things look like before you start a job. Small cost in the scheme of things, and some reassurance that you know what is recommended, even if you get someone else to do the work .

    PS I am a mechanic but still buy a paper manual !

    Friction dampers require periodic service. I commissioned the construction/copy of the factory tool which makes it easy. I have at least two left if someone needs one.
    Friction dampers are ingenious little devices. Proper service will restore the correct suspension rebound characteristics to your A series car.
    I have not posted much lately. Health issues and trouble logging on a great deal of the time.
    Most reliable way to find me or my team these days is through the word of mouth grapevine or at (One big word) grand central Citroen dot com.
