humming road speed related .hums straight line and turning left when turning right sound goes away ...
so put car on axle stands to spin right wheel vibration and humming
so replaced osf wheel bearing bearing and
replaced inner and outer cv joint
still the same no difference
when up in air on axle stands sound went away when drive shaft was off
so i am thinking diff

so got hold of output flange from gearbox and i can rock it left and right but with a click....

tried same test on another good passat and no clicking ,,

question is there some kind of preload which can be adjusted cos on other side of box there is a ring of bolts ,,which might give me acess anyone throw some light on here
