VLSD: Check

[BuudWeizErr]

I think this has probably been covered before, but search turned up wayyyy too many threads for me to check them all.

I'm going to pick up a JDM VLSD from an S13 Silvia tomorrow. It was a 5 bolt output configuration, but they output flanges were swapped with the stock, open differential 6 bolt out flanges for a complete bolt on affair.

How do I tell (with the diff out of the car) if it is actually a VLSD or just a regular open diff?

TIA.

did the discussion about the presence cooling fins prove to be worth anything, i dont remember if it was deemed truthful or not.

I mean by turning any of the flanges...

There is a way to tell. I wish I could remember exactly which diff did what. I believe the open diff if spun, the wheels will spin in oposite directions. With an LSD they will both spin in the same direction. Someone please check me on this.

well...when i picked up my vlsd for a 95 240sx they both turned in the same direction.

when i swapped it out the open diff, i believed they spun in different directions.....

yeah i just went outside to go check, they spin in different directions....i'm talkin about the open diff.
