How to tell if a LSD is working

[red truck]

My sons' VY one tonner is supposed to have a LSD in it from the factory, but the previous owner put a lower ratio diff centre in it.
I suspect that either the new diff is not a LSD, or it is stuffed. We had one back wheel jacked up today to change a tyre, and noticed that the wheel was free to turn.
Is this a true indication that the LSD is non existant (or buggered) or does the diff have to spin up under power a bit before it starts to lock up?
With a LSD the car should drive off the jack, but didn't wanna try this in case it mangled the jack.

sounds like either the lsd is stuffed or its got a single spinner in it. you could maybe test by doing a burnout on a dirt patch somewhere lol

mate i wanted to test if my vl had a lsd and im still not sure, i dont think the burnout on the gravel will work, i tried on the grass and it did do double leggers. but on the road it only spun one and other times two lol im confused

only way i can tell is to jack the car up at the rear and spin the wheel with your hand and if the other wheel spins the oppisite way then its LSD haha theres prob better ways but thats how i tell :yeah:

None. It's the other way around. If both wheels spin in the same direction when turing one then it's LSD.

Have found a complete rear axle assembly at a wrecker in Sydney to suit a tonner (live axle), but the donor tonner is a V6 auto. Wrecker says they are the same as the V8 manual, but ...wreckers..mmmmmmmm

Can anyone confirm if the diff is the same?

I highly doubt you have an LSD. They were an option on the Acclaims but most of the Acclaims went to families. So unless you car is optioned with some other stuff dont get your hopes up.
