Steering or Suspension?

Question

Hi allMy 1998 C-Class 230K Sport has developed a knocking noise.  It comes fromthe front of the car and sounds as though something is loose.It's particularly noticeable when travelling on an unevenroad/pot-holes/speed humps(to be polite) - in fact most of the UK roadnetwork.Strangest thing is even the wife has noticed it!  Shame she didn't hear therattling timing chain on her Audi 'til it was too late, but that's a anotherstory.So:Steering or suspension?Anyone know which is more common on C-class?Are there any other likely possibilities?Where do I start?Laugh first the post your ideas.Thanks

It might also be as simple as the sway link bushings. These can emit a slight "knock" when the lossen up.

BTW, my wife can't tell when her car is having problems either. Of course, I probably would have save thousands by not fixing things until she noticed them.

I would say it is suspension... particularly the struts.or the strut mounts.

I would guess it's a suspension thing too. If it was steering it would be more likely to happen all the time. As it's happening on bumpy surfaces it would lead me to look at the suspension linkages, bushes and dampers first. Mike
