[up2u]

hi guys my car has a problem need help to diagnose what it is ( as i drive off there is a rattle starts from the gearbox area is not the engine as the rattle only happens when ths car is moving when i excelarate the noise is constant and if i lift my of the power it`s still there the matalic noise gets less as the speed decreces (have checked the tranny oil it`s ok ??
the car is a 2001 c270 cdi 93000 miles and it`s the 5 speed box

cheers up2u

parking brake cable???

I have the same problem. And I also have problems with my parking brake /not releasing easily somtimes/. I suspect that the parking brake cable is to loose and it is hitting the driveshaft. Or it is a piece of plastic broken which is holding that cable. I was trying to find it today, but was not able to locate the part, I might need to take the car to the garage. Maybe my guess is wrong, I would appreciate your comments. Thanks.

Could be the same problem I had on a C Class and sounds a bit like Janko39's problem....lose handbrake cable that was tounching the Propshaft....common problem according to my Merc Indi.

have a look

is the noise when driving and on take off and at certain speeds it might not be so bad


i bet its the 10p rubber bush that joins the auto gear stick to the linkage under the gear stick they wear and fall out quick fix

remove center console
in gearstick area
four alan key bolts hold down the auto box gear stick remove them

lift up and you will see a flat plate going straight down with a ring on the end i bet its got no rubber bush in it and the linkage rod that clips into it is rattling i have done this so many times on mercs and people thank me for getting rid of that noise that drove them mad

i know this is a manual gearbox linkage but see the three flat plates their is only one in an auto and the rubber goes in the hole that this bar clips into see the 90% at the left it has a grove that fits into the rubber and a clip holds in place

hi this is time to put my hands up the rattle on the car was the hand brake hitting the prop shaft and not the center bearing so will put the bearing on the shelf for a later date !!
this was really funny because it sounded like a drying bearing with a badly pitted bearing track so i am asking people that find themselves in my predicament please check first not after as i did
yours up2u

PS, the car is really quiet now!!
