On my 94 C class I am presently being driven mad by the drivers seatbelt squeaking where it goes into the pillar right next to my ear. It sounds like there is a dry plastic roller in there but my examination so far, shows that the belt goes through a standard plastic coated loop. However the surface of the belt that rubs here whilst the belt is in the normal wearing position looks to be a bit polished and it only when this part of the belt is moving in and out of the loop that it squeaks. I think this is probably a common problem as a friend mine said He had the same in his C class.

Has anyone found a suitable lubricant to put on the belt surface to stop the squeak that won't damage the belt and come off all over my clothes? My initial thoughts are maybe a bit of talc or soap. Has anyone any experience of this and got any recommendations.

Any ideas much appreciated.

Yup... I've got the same problem on my 95 C280.

However, the squeak is from the passenger seat belt... and happens only during the winter, or cold weather. Also, it will only squeek of the passenger moves forward or towards the center of the vehicle...
but yes, very annoying. I'm thinking about using some silicone spray... I'll have to inspect how I'm gonna do it though.

Good luck.

Use some sort of dry silicone type spray lubricant.

Good luck,

Yup! Another sufferer of the squeaky seatbelt syndrome!!! Its so annoying that people sitting as passengers will ask me what's that noise like somethings very, very wrong somewhere? Mercs don't squeak or rattle they say, but mine does. Mine is on the driver's side and squeaks everytime I try to move around in my seat like reaching out to the glovebox, also when I try to work the radio switches or the sunroof or the cabin lights. I only have to move just a bit and it will squeak. No need to turn around and try to reach into the back seat! Haven't found a cure yet, but willing to try anything suggested by you all. Cheers!


1994 C180 and enjoying the hidden problems and curing them.

In board seat belt buckles squeaked on the '91 300E.

"Erk, eek,erk...." especially in cold weather.

Driving us all crazy. Pulled the anchors this way and that. Forwards and back.

"Eek, erk, eek ....." Nothing helped until ….

.... I used silicon spray with the tube. Inserted the tube in every opening I could find and gave it a shot. I wiggled the seat belt anchors around and made sure all the parts got a chance to get blasted.

Quiet now

Until the shifter bushings wear out, then they go squeak, squeak!

But that's another story...

update on the sqeaky seat belt... managed to get some silicon spray the other week (not cheap cost £8 for a can) but a little spray on the shiny part of the belt has stopped the sqeak. Result cheers for the suggestions.

My driver's belt is still squeaking even after the tech tried to spray something into the wall socket. What silicone can I get to try this again, the brand name and what it comes in, tube or spray can? Won't the spray damage the actual belt or make it wet and greasey? Will it damage the mechanism inside the wall, the locking and rewinding mechanism??? It drives you nuts on a hot day when you have to see so many customers in different places. HEEEEELP!
