:biglaugh:I went and got a rear diff for my 88 turbo and was wondering do you still have to put in the additive stuff with the gear oil? Also I can't find 90 weight oil any where which is what is called for this time of year and the parts store told me its a special kind that toyota sells, somthing to the effect of "hydrostatic" oil? Thats what they said I believe. Thanks Again.:icon_razz
