Squeaky Rear Suspension on c240

[antoine_lee]

Hi everyone:
Anyone know why I can push down on the back of my c240 and it squeaks louder then an old bed and box spring mattress? Even when I drive and past by a wall the sound bounces and sounds like something is rattling or loose, but if you look under there I don't see anything cause everything is enclosed. The dealership I normally go to is not good with finding problems and has terrible customer service to say the least, so I don't want to take it in. I would like to do it myself if possible. Any ideas?

squeaks

Hi Antoine
Working on the principle that nothing is broken/loose etc
The old school way of stopping squeaks was to spray the
underneath of the car with old engine oil (noise suppression and
Rust prevention all in one) might be worth buying a large can of WD40
And hitting all the bushes and suspension parts that you can get at ?
(cover the brakes before pushing the button)
Good Luck
Mike J

check the rear springs!!!! the bottom coil is prone to snapping and rattles about in the bottom arm.
