    are any of the suspension parts common /easy to identify lads for wear and tear . im getting a rattle over small bumps , nothing on flat roads or over speed humps, ( silent ) only seems there on longish stretches of small bumpy road / pot holes etc .

    much obliged for any help .

    Could be that your brake pads are not a perfect fit. Aftermarket ones especially can be slightly too small for their carriers and as the wheels shake over the surface they shake in their carriers.

    If you go over cobbles to produce this sound, with your brakes slightly on, if it silences the rattle, it'll confirm it's the pads. If the sound remains with the brakes lightly applied, then it's not the pads...

    Lower front wishbones? Easy to identify on a ramp. W211 ones from online retailers about 25% of mb price

    Don't know the set up on your car but I've had similar noises/ conditions on cars with drop links failing.

    My r129 turned out to be disc pads with the very same symptoms but the rattle does happen slightly now and again

    I'll third drop links. Anti roll bars are under no load until the wheels are moving in opposite directions.Small bumps find all the play in the ball joints. Who invented these things anyway, rubbish idea that's produced yet another 'service item'

    Don't mess around with suspension and steering ........ get it checked professionally.

    Lie under the car and wobble the anti roll bars, tap them hard with the palm of your hand, if there is any sort of play at all they need replacing.
    They are like butter on mercs.

    both rear exhaust heat shields broken off their fixing points - been rattling on rear silencers - wedged for now with some foam , until I can maybe pop rivet them back on somehow . result - no more rattling and free of charge a fix .

    I don't think back boxes on diesels get anywhere near hot enough to warrant a heatshield.
    When one of mine broke loose, I removed it.

    im going to get 2 big washers and attach them over the original fixing pegs with araldite and silicone - once set with the foam in place they should hold in place again .
