I have a 1999 model td5 had it for 4 years now. Not too long ago it had started to make a chirping noise it doesn't seem to be related to load, revs, bumps or braking. I have just replaced the front drive shaft as i was sus of that the exaust manifold has no cracks and i today just checked all the pullies on the front of the motor just in case.
The noise does seem to be coming from under the car and only when its moving, doesnt really matter what speed though. I've checked all the hubs doesnt seem to be anything a miss there and the brakes are clean and the pads are pretty new.
It does sound like metal rubbing on metal
Thought someone here may have had this before?
