Deaf Rattle: I topped up the oil, should I try and replace it all? I would be quite keen for you to listen, are you in Auckland? I can replace it myself, its just that this is a rare as fuck diff and I will never find a direct replacement in NZ.
mkcortina: That's right. When I jack up the rear and go to listen to it, its soo loud that it sounds like it's comming from everywhere, but I'm pretty sure it was the diff housing.
Is it possible to do some kind of hilux conversion in which you only swap the head and maybe the torque tube?
