RX models, I think all years; optional on GL-10 turbo models (mostly '89). Some early model Legacies had a 3.900 VLSD. I don't know of any others. Label on diff is very clear: LSD 3.700. If the label is gone and the car is off the ground, turn the wheel; if the other wheel turns in the same direction it's either a LSD or welded diff; if it turns in the opposite direction it's an open diff.

The info is in the FAQ sticky in the off-road forum:

LSD Info!

What year models?
-late 80's Full time 4WD RX's
-late 80's GL 10 Full time 4WD
-Came as options on all ea82's
-Full Time 4WD XT6's (Only 3.9 LSD)


How do I tell If I have an LSD?
-Look for this photo: (Thanks Dr RX!)
Posted Image
It should be mounted on the rear diff.
-Get your soob's rear end off the ground and spin a tire, if the opposite tire spins in the SAME direction, you have an LSD.

Things to Know about the LSD
-Almost all lsd's come in a 3.7 ratio, this needs to be converted to 3.9 on most soobs to be able to run.
-Never run different tire sizes with an lsd.
-The VLSD is not too good of an lsd for offroad use.


How do I change my Lsd from 3.7 to 3.9?
