HJ75 diffs

Can confirm this. All 1981-1990 40, 45, 47 ,60 and 75 series difs are interchangeable. After 1990 the front diffs were hilux diffs and will not fit in the rear. One thing that is good in the 1981-1990 vehicles is that when the rear diff gets towards the end of its life just simply change the fron over and get a brand new diff in the rear. Most front diffs wear less than 10% of the rear and stay as good as new for ever if only in the front end. Once the almost worn diff is put in the front then it is usually great for years as most 4x4's get minimal use off road. I new of a diff repair shop that used to do changeover diffs for Toyotas and never pull them apart. They used your own and changed them over. They just swapped the front and rears over and never told the customers. I never went there for repair work after hearing this.
