My JX has developed a rattling grinding noise when idling. I thought it was the shot bearings in the alternator because when i removed the belt the noise disappeared, so went out and bought a new one (expensive!) fitted it but the noise is still there. I am wondering if the problem is the water pump but it doesn't leak or have much free play. When you accelerate the noise disappears.
Anybody had the same problem.

do you still have the metal undertray......mine used to rattle like mad on idle....sweet as a diesel when running.

No, its def the waterpump, belts, or alternator. I'll try changing the belts and see if that works.
