We have recently bought our first Fourtrak after two Sporties. It's a 2000 2.8 Independent. Our main concern is a noise that initially seemed to conform to an exhaust problem. Both the supplying garage and our Daihatsu dealer have investigated with no luck. The trouble is whenever you want someone to hear the noise it remains conspicuous by it's absence. The noise is a deep drumming vibratory sound that seems to come from beneath the car. At the moment it seems to be heard only between 1500-2000 r.p.m. (nearer 2000)and can occur at almost any time but mainly, I think, on poorly surfaced roads. I know it is incredibly difficult describing and locating noises but we hope that maybe someone else has come across this before. Our dealer is going to replace the split rubbers on the torsion bar as they feel this could be contributing to the noise. Does this make sense or is it clutching at straws?
