strange sound from rear near side suspension?

[drivinggod09]

how do all merry christmas not much to write about apart from a srange sound coming from the near side rear wheel/ suspension area of my 2001 230CLK its now got 107000 miles on it running fine handles great still its just making a sound like a flat thin piece of sheet metal that when you flex it and it pops back into its flat original shape makes a boing sort of noise , thats the best i can describe it. It makes this when the rear wheel just gets on a speed bump or it dips into a pot hole or drain or something like that . i jacked it up yesterday and as the jack took the weight it made it again i took the wheel off and checked all fittings and the spring looks ok the exhaust isnt hitting anything and everything feels tight and solid could it be a damper or bush when its back on the ground the suspension settles nicely when pushed down on the rear quarter. like i say it drives and handles fine any sugestions what this could be

ohh yeah and the temp indicator is playing up showing half numbers

Second one today,, give the roll bar bushes a few good squirts of silicon, could be better to jack the side when doing it to relieve any pressure on it. Silicon is very good for rubber

 

[drivinggod09]

silicon where can i get that is it in a spray can like wd40 wheres the roll bar bushes ? il just spray all the rubber bushes cant be a bad thing

 

[television]

Tool shops and halfords you get the spray.

just spray all of the bushes 20 mainly and both ends of 70

For the sake of £4 its the cheapest fix that you can try

what else could it be a new rubber bush needed or spring broken ?

Not un-heard off for the 208 to break a spring, or any merc come to that!

Interesting article on springs in this months trade mag

Is it not what's the damage on a spring assuming that's what it is is it true they need to be replaced in pairs just thought wouldn't that be picked up on a m o t ?

All MOT testers look hard for broken springs, and you would be lucky to get away with one on a test

well i washed it today took the wheels off cleaned all the gunk from the lip behind the arches and sprayed silicone on as many rubber bushes as i could see the noise hasnt gone away but il give it time to work in or do whatever it is silicone does best i checked the spring again i cant see anything wrong with it but it goes up behind a plastic shield so maybe bust further up who knows nut like television said id be lucky to have it pass the mot and it was making that sound before that too

ound it got a broken spring on the rear nearside only the very bottom the last inch has broken off and is rattling around quoted 80 pounds to replace how much is the spring aprox and can i buy single

 

[drivinggod09]

are there 3 colour codes on the springs for diferent strengths ,merc says there are and are marked at the top of the spring , i cant see it untill its off. anyone know what colour is on mine or is it another way of making me buy 2 springs when i only really need 1,

 

[television]

Surely MB should know by the VIN what they are

 

[drivinggod09]

hes just phoned up and told me they are red and told me that i should replace both to make sure they are the same colour/strength ???
think i might phone warrington MB instead see if the guy there knows any other language but jibberish

Hi Rob, suggest you give MB Tech in Warrington a ring. I'm sure they will give you all the info you need. If you want the telephone number, I will go and get it.

Always replace springs in pairs, thats standard good practice

is it ive heard that before but why i its the same make and pat why fix it if its not broken my renault laguna had a broken spring only replaced 1 that seems fine and that was 4 years ago your thoughts

Had my C class serviced at the weekend by a good indie. Needed both rear springs replacing and was charged £40 each for the springs (they are black, by the way), plus labour. Total inc VAT and fitting around £150. She's sitting better and no "boing" now.
