    So spent the last few nights replacing the rear shocks as one had totally leaked out.

    first of all, mercedes have replaced the a2113262700 part with a2113266800 retail at £386 + vat each and you need two!

    So before you start have the following tools at hand
    - 17mm socket and spanner
    - 5/8 socket and spanner(or good adjustable spanner)
    - 10mm socket
    - 8mm socket
    - flat head screwdriver (smallish)
    - 35 torx (if you have luggage hooks in the boot)
    - vice grips
    - 2 x jacks
    - Rags
    - length of thin wire\string

    first start by stripping the boot liner on the side of the shock you are replacing.
    - there are two push clips near the top, use the screwdriver to ply these out
    - unclip the hinge surround and either tape it to the hinge or carefully remove it, they can break easy.

    - if you have luggage hooks, unclip the screw cover using the screwdriver and use the torq to unscrew and remove.

    This should allow you to remove the cover carefully.

    Jack up the car from the jacking point and remove the rear wheel.

    remove the lower rear wishbone cover, it has two clips, be careful as they may break s they get brittle.You may want to give this a good degrease before putting it back on.

    then using the 5/8 socket and spanner, undo the nut holding the bottom of the shock in, but DO NOT remove the bolt yet.

    Then move into the boot and attach the vice grips to the top of the shock to stop it spinning and use the 17mm spanner to undo the nut and remove.

    Make sure the hub is jacked up nice and high by the 2nd jack else the shock will spring down and the nut will ping off and may cause damage or injury.

    you can now release the jack holding the hub and the shock will come out

    now undo the plastic 10mm bolts from the wheel arch liner and pry the plastic clips out and remove the whole liner. You can remove a few bolt but its easier to work if you remove the whole thing,

    [​IMG]

    follow the wire from the shock round and pull out the rubber holders and release from the plastic clips. Flick the metal clip out which holds the plugs in. you will see it attached to another plug, this separates easily.

    Hammer the bottom bolt out and you have a shock removed!

    installation is reverse of the above.

    you can reuse the rubbers as they do not come with the new shock or order new ones, mine were still in good nick.

    Before installing the new shock, press it down to compress as much as possible and tightly tie a bit of wire to the top and bottom of the shock to stop it coming back up, this will make it easier to get back in.

    [​IMG]

    after putting the bottom nut and bolt loosly in, use the jack to push the hub up again to allow you to do the top nut up.

    pics were taken during left and right removal so dont let them confuse you on side.

    once all put together, take it for a spin an feel how different the backend is!

    enjoy
