its hard to say, ive had plenty of ropey cars and non ropey cars with little knocks. in my focus it was the cheappo exhaust that wasnt quite the same shape as the original... anyway
whilst i will be happy leaving it up to a garage, im also comfy with replacing small bit like this if its worn. (see my other post) im not sure how long my inspection is due off so if its obvious and straight forward to do then why not? i did the clutch on my other car last week and that involved taking the engine out.
the clunk is only noticable on really bumpy roads. (liverpool is good for them) but mainly on my drive or the car park at work where your going slow. they are that gravel stone squashed into the ground type affair where holes just appear, the car park used to be building.
it sounds like its from the front, its sort of a low level clunk rather than a rattle. very similar to a bush thats worn or if soemthing is hitting a stop of some kind. you cant really feel it thought the floor or steering. its not loud at all so only audible when going slow over rough ground. its not the sounds of stones hitting the underside.
at first i thought it was just a normal ish noise for the suspension moving about. but from other posts suggestions that the drop links fail easily im wondering if its these. its nothing that i am very concerned about, thes steering is fine and precise. there is no slop in it. when driving i'm not getting any of the signs where it jumps or moves suddenly and im not getting any kind of odd tyre wear so a little looksee is probably worth it
