Rattle 1993 b2200
 

I have a ratlle when my my truck is idleing gets loader when stoped in any gear then goes away under acelaration. I changed the cooling fan idler bearing and it's quieter but still there. Anyone know truck has 180000km on it and has been looked after as far as I know. Cheers Jason

A rattle is usually a loose exhaust heat shield. Check around the exhaust manifold and catalytic converters.
