How do you idenify a 4x4 lsd and what ratio it is ???

i think most are 3.6ish. 4x4 is probably irrelevant, i dont think its different to the 2wd LSD. Try turning the output shafts seperately and see what happens. All guesswork though so scuse me if im wrong...

As Joel says, the diff ratio is 3.62:1 therefore the prop turns 3.62 times to the output turn to do 1. When testing an LSD turn the input (prop) shaft flange and both the output's turn in the SAME direction. If they turn opposite way's it is likely not to be an LSD. There should be a good resistance when turning an output flange for the other output to turn the same way...

All IMHO of course...

I have the lsd on my build. Hellfires description is spot on.

Thanks guys im going to look at one tommorrow .

Cheers Drew

bear in mind that turning the input shaft on a nonLSD may still result in both output shafts turning the same way at the same speed. Best check how hard it is to turn the outputs against eachother.
