hey guys, i have owned my s2000 for few years now and been up and down with common problems that i have fixed, now another noise has come up. whilst driving 1st and 2nd gear has a slight winding like a super charger (not as loud as one) but you can hear it winding up and then 3rd or 4th there is no noise. i never thrash the car always drive it normally i hardly vtec it anywhere these days. could it be needing new bearings or diff,the noise is coming from the rear for sure though. its not as loud but you can hear it.
