Is it possible to use a rear diff for the front? Like, if you wanted to do a solid front end on a Vit... could you adapt a rear?
Yes?... no?... am I silly? (Don't answer that

)
Its all possible , Money or fab work
It will probably cost more to fab the one front diff machining -axles treating ect
, than to simply do the yota thing front and rear.
If the engineer spys the difference for the reconstructed front housing he may want all sorts of info on its specs ,
where as with the stock toyota stuff they can get the info off the
vehicles spec sheet .
One more thing to add from the strength point , although the vit rear is a much larger ring pinion then the sierra and by memory larger then the front yota lux by a bit it has a ring and pinion cut for the rear rotation
when place it in the front the Ring pinion run on the back side of the teeth making probably only as strong as the smaller lux front member .
Ive actually been thinking about the yota swap thing lately my self for
sierras ect , I think the lux front s good , if i done one the rear would be where i would spend some time , most probably use the lux rear centre and and 75 series outers and axles (im thinking 60s axles will make it to wide in comparison with the lux front), creating an offset small centred diff for the rear. elevating the tail shaft lineup , yet giving better clearance than the 60 series or MQ rears .
Just some thoughts
