YES there are non VLSD J30's!

A buddy of mine owns a 1996 Infinity J30 with a 6bolt diff, it has 110,000 miles on the clock. His rear wheels spin opposite of each other when raised and turned.

He also owns an s13 with a 95 J30 VLSD 6bolt, these halfshafts spin the same direction when raised and turned.

We opened his J30 diff and there was no doubt it was an open diff. He swore he never touched the diff since he bought it.

There you go. Misleading info can be put to rest!

Check the diff before buying! Or wasting your time swapping it over just to have another open diff.

Like I said, people still read this stuff when searching google. I hate reading threads that end with bad info, Or no useful info.

ALL j30s ive worked on are vlsd. MAYBE his could have been a recall and turned it into a open? Which the customer would not have noticed since most dont. His car has to have been tampered with before in that area. Just because he didnt do anything doesnt mean the PO or owner before the previous didnt take it in to have work dont that became a head ache.

Ive seen a broken vlsd before where it was being held together just with the axle stubs... So anything is possible unless you have full documentation from the day the car left the dealership.

That's possible. The gears looked intact and seemed to function normally.

This makes one, confirmed with an open diff, so it's likely there could be more out there. It's there and looks just like any other J30 diff, so the possibilities of buying an open j30 diff off the interweb are there. Even if chances are slim.
