    Hi all,

    I have a little rattle in the mornings from my '95 300D and traced it pretty quickly to the top bearing-bush in the shock absorber of the belt tensioner.
    If you just apply a little pressure to it with a finger, the noise vanishes. It's generally quieter when the engine's warm too.

    I spoke to the local independent MB tech and he said these items don't generally last more than a year or so before becoming noisy again - is there an upgrade for these plastic bushes perhaps to extend the life of the part??
    I have a receipt from 18 months ago showing the part was changed then so perhaps it's true? A weak bit of Engineering from MB in the early '90's, surely not???!!!

    Thanks


    Paul

    Undo the damper, push the centre rubber out of the eye, wrap material loom tape inside the metal eye, push the rubber back in.

    Thanks Nick, Dieselman - washers on the way.
    Can't understand why this wasn't fixed during production??
