Hi there, i've recently come into possession of a 1989 4wd L300 sportpac. I was wondering how/if you can tell whether it has a LSD in the rear?
I have read on several places that you jack up both wheels and spin one, if the other rotates in the same direction it is an LSD, if it rotates oppositely it is not. - Now performing this test, both back wheels rotate together in the same direction(with the car in neutral). However, if i put it in first - so the drive shaft is fixed/doesn't move, and re-perform the test, the wheels counter rotate. It is also possible to turn one wheel while the other is grounded (in neutral), but it takes a bit of effort...
Can anyone clarify what this means?
Sounds like it may be an LSD. Have you tried parking one wheel on say wet grass with the other on bitumen. You should be able to move off without the wheel on the grass slipping much...
