Rear end knock/clunk

[Jase25]

Hi All,

Another problem on my 1998 C200 Manual transmission - will it ever end...

For a while now I have been hearing a clunk at the rear when I take my foot off the gas and again when I put my foot back on to accelerate.

At low speed driving in traffic this goes along with the car jerking each time I take my foot off the gas and again when I put my foot back on.

It is impossible to drive the car smoothly in traffic.

Please help with ideas of what this could be and how I go about diagnosing it.

Thanks,

Jason

Could it be the front or rear flex disks?

I looked under the car and they seemed ok but I don't know exactly how to test them.

The other thing is the transmission mounting seemed quite flexible when I removed it to do some work on the clutch slave cylinder hose above the gearbox. Is this right or is it supposed to be stiff?

Thanks,

Jason

you may want to look into the Flex Disc I am doing that as we speak they go bad and make the clunk noise you refer.
