Noisey diff in YH63 Hiace

[cat007]

Hey all

my 1987 YH63 Hiace has a noisey diff. I never thought anything of it until now. It's not grinding or sounding that bad - its just a loud low frequency hum.

I imagine it will last for another 50k's or more - but just to be safe....

I haven't looked at the VIN plate yet but just wondering if anyone on here knows what sort of diff these things have? It's a manual 2.2L petrol

Is the diff head interchangable with any other toyota's? Finding an LSD would be ideal but not a requirement....
