Think this might have been raised before but would like to see if anyone has changed any components to rectify:
The sounds can be made with 2+ people in the car (Easier with more people
in). It does it on mine (RB5 17 " wheels and also on my mates MY99 with 16" wheels). I don't think that it is a tyre rubbing against the strut because I have not seen any
evidence of tyre wear on any of the tyres that I have had over the last year. Also I have made it make the sound with the car parked, opening the boot and bouncing the rear up and down by pressing on the boot rim.
Therefore, it must be spring / bush related????
Dealer has check my mates suspension etc and cannot see anything worng.
Scooby 'feature'?

All help appreciated...
