A LUV 4x4? Can be done, I've got one (two actually, Trooper has the same rear, just different ratio). There is also one LSD option that can be retrofitted.

yea that LSD is in a RWD isuzu turbo car
87/88 or 88/89 :?: never can remember, yea very few and hard to find.........
only auto to get a LSD for the 10 bolt rear axil :(

if you find one it also has a funky 3.90 geared rear end and a 20.0% O\D trans all the other O\D MSG tranys are 14.5%
GRANTED THAT STUFF IS WORTH LESS IN A 4wd.

never-the-less its in demand if found for a 2WD ride. :P

yep, its the only bolt in LSD that Isuzu offered state side in the rear 10 bolt......

only the turbo RWD cars have the LSD,
it does not have to be a turbo to have the 3.90 gears or 20% O\D 2WD trans.

To change the rear carrier to LSD you first have to have the LSD carrier from a RWD Turbo Impulse (mid 80's through 1989). If the LSD carrier is still attached to the stock Impulse 3.90 gears you have to remove it, then remove your stock carrier, attach the 4.10 ring gear to the LSD carrier and install the LSD carrier/stock ring gear into your stock housing, which requires shimming the new carrier to obtain the proper ring and pinion contact pattern. It's not a complete differential tear down and rebuild since the pinion gear was not disturbed, but it's probably best left to someone with differential rebuild experience. One down side, you have a 20 year old LSD, the clutches may or may not be in good shape. On the upside if it works well you have way better traction, probably out $300-$400.
