righto i've been having problems with my Mpi.. its a 2000 Wreg..
when i drive the car i get a whirring / buzzing noise from the car (noise kinda sounds like a moped

a couple of months ago i removed the driveshaft and pot joint on the right hand side (OSF) to replace the gasket on diff side cover. refitted everything and the oil leak was curred.. however around the same time (although could be a coincidence) this whirring noise appeared..
i have had the (OSF) driveshaft out a number of times since to try and rectify the problem, i've checked the wheel bearings (both sides new before noise started) and they're fine.. ive replaced the bearings on both ends of the (OSF) driveshaft including a new pot joint..
so before i do the same to the (NSF) driveshaft i thought i would ask the question here as im stumped!!
im really hoping its nothing inside the gearbox!!
cheers, Aron
