Creaking suspension C Class

[bibamus]

Sitting for half an hour in a queue of extremely slow moving traffic yesterday in temperatures approaching 35C. When the traffic started to move, I noticed everytime I pulled away or hit an uneven piece of road, I got this horrible creaking sound from the front suspension. When I got to work, I couldnt hear it anymore.

Bouncing the car up and down, pulling the wheels etc didnt replicate the noise, nor did driving it about over speed bumps. So, I left it.
Today, driving slowly in the heat and the noise started again, so I got out and bounced the front of the car up and down and the noise is coming from the FOS anti roll bar bush. The bar was very hot from the heat of the engine, its obviously moving inside the bush and creaking as it does so. The bush seems pretty new by the looks of it and there is no wear apparent.

If I lubricate the bush with something, will it have any adverse effects on the bar? Is this a common problem? I heard a very creaky E200 this afternoon too, I assume he is suffering from the same problem.

very common problem, cheap to repair. I'd take it to an independant specialist.

Silicon oil is a very good lubricant for rubber, the aerosols that they use for router cutter blades is ideal. try and move the bar when you do it, so that it runs down inside.

Our C280 does this as well every hot spell

the creaking dissapears with the first rain. Silicone spray lube works just fine, as Malcolm said.

I`ll try the spray first, it only seems to creak if travelling slowly or stationary, in the heat. I`m off to S of France Monday, I`ll probably change the bushes when I get back.

My C32 does this too, but as you say, only when very hot. Wurth have a spray called HHS2000 or similar, which I happened to have to hand and cures it on mine for ages. I suppose new bushes on the a/r bar would be the answer, but I'm always too busy with other peoples cars to work on my own. Cobblers children I guess!!

BTW S class suffers similar fault, but bushes come complete with anti-roll bar for them!! Talk about cheeky!!

Ive got creaky suspension on the rear since I had it lowered, however it didnt happen straight away, couple weeks after, any ideas? Especially since the hot weather came in?
