Whilst not perfect, the 4.1 remains the closest match to 33's from this table.
I might stand corrected, but I thought that the ADD was all contained on the axle tube and the diff housing was the same part number on the Hilux and Prado. Therefore swapping the diff over and keeping the Hilux axle tube which is held on by 4 bolts should retain the ADD. Anyway, that was the outcome from the initial research Max and I did. My truck is an SR so I don't have direct experience but i did retain the axle tube.
an any body confirm this? Is the ADD just fixed to the axle tube? So the actual
Diff can be swapped say from a prado into an SR5, the SR5's axle tube just needs to be retained?
