Suspension Knocking

[M3 SHAM]

Hi guys,

I have a 2005 C180K (sport pack) with 160,000miles on the clock. It is a saloon and it has recently started knocking when going over rougher road or bumps. The knocking seems to be comming from the front and the back and particularly from the back when underload.

So I have given my car to my trusted mechanic of many years and he has checked the car over for me. Informs me that the links on the front are shot and that may account for the knocking from the front. However he has says he has checked the back suspension can not honestly find anything that really needs replacing

Anyone got any ideas or no if there any common bushes etc or any other suspension parts that may not necesserilly be obvious that may need replacing?

Any help much appreciated

Front links and D bushes are common.. best to get them all done whilst he is there.

On the rear the only common thing is rear springs which go out of shape and catch on the perch... but thats more of a twanging sound.

From the back it is a different sound from the front almost sounds like to bits of metal hitting each other

mine sounds really loose too at the front. loose knock on bumpy surfaces. however the trader I bought it from got it MOT'd like this. shouldn't/wouldn't worn bushes fail an mot? dodgy MOT?!
