Took car out for a blast begining of month to bed clutch in and had noise from rear pass side after having a look we couldnt find anything obvious was drive shaft location and as the pass rear cv's were old i ordered new ones and replaced at same time i noticed diff weeping and it has whined for the last 6years or so it has always had oil so I Ordered diff overhaul kit (all bearings etc) to have it sorted after classic ford.
