The noise is like an intermittent grind. Thats why I originally thought the brakes were catching, or grit in them. It seems to be coming from the rear drivers side. ( Grrr. Grr. Grr.) But mainly at low speed. It gets a bit louder the slower you get...
I could be noisey bushes....But wondered if it is a common problem...
Also does anyone know what the exhaust bore is on the V6, is it 2.1/2?
