Hi all. Newbie here. Ive got a 2000 hiace with a very noisey diff, not clunges or shudders, but really loud. I was either going to get it rebiult (wheel bearing and reshimmed) or find another diff. Hence, any idea on how much to rebuild a diff in these? Also, if I went for a new diff, does it have to be out of a hiace? I heard hilux and corona diffs fit too. Its a SWB 2.4 EFI Manual van. Thanks heaps in advance Ty
