S40 clunking noise
Hi all,
I appreciate how difficult/impossible it is to diagnose a problem from someone elses description, but I really need some pointers to try to locate a clunking noise from the from end of my S40. Its a 97(R) 1.8 with c80k on the clock. There is a 'very' annoying metallic clunking noise coming from the front end, on both smooth roads and rough roads. With the windows open trying to listen for which side it is, I can't hear it, however with the windows up it is quite distinct. To my 'untrained' ears, it sounds (and sometimes feels) like its coming from under the center console or around the bulkhead where the pedals are, its almost as if something is loose and swinging around. I have taken it to a garage who have had it up on ramps and tested the bushings, but they have given it the all clear (suspension wise). I did have a look underneath the other day, and thought the gear linkage was quite loose, but I don't think this can be the cause, as if I drive it holding the gear lever, the clonking is still there. I'm at a loss for what to look for next. Does anyone have any ideas or thoughts what this could be????? Here's hoping Neil |

Might be worth looking at the driver's side engine mount. They are prone to failure and can cause all sorts of clunks and knocks.

Have someone put the car in gear and make as if to pull away, but with the handbrake on, whilst you look under the bonnet. If it is the top mount, which is most prone to wear, you will see movement, and hear the clunk. If not, well that's one possible cause to cross off the list! Best of luck |

Top mount bearings on the front struts would be my chief suspect. Open the bonnet and keep your eyes on the struts when bouncing the car - if the struts don't show signs of movement you should be okay, I can't exactly remember what mine did - I think the dodgy one showed signs of movement.

Well, took off both front wheels, went around the suspension bits with a 'jimmy bar' (for want of a better phrase), and found that the lower mount of the nearside droplink was decidedly loose, almost loose enough for the nut to be turned by hand. Tightened it back up, test drove it, and the clunking has gone, yippee!!!!!!!
