LSD How to tell if it is working properly

[Sparkie]

G'day
I am from Aussie and own a 1992 xs V6 Jackaroo and I would like to know how I can test to see if my LSD is still working how it is supposed to.
Tried jacking up one back wheel and putting a brick under front tire and driving over brick but it would not do it. I think my LSD is stuffed but need a way to make sure without to much mucking around.

PS Car has done 230,000k( sorry dont know in miles), what is the average life of a LSD

TIA

With that many miles, it might be "tanked," as we call it here in Nebraska.

One way to check is to jack up one side and ride the brake, while applying a LITTLE throttle. If it starts to move, it's still okay.

Thanks for that.

I will try that but you may be right. I am not very hopefull.
