I'm suprised people are having problems with their LSDs. On my 2002 it seems to work pretty well. Granted, I don't do rock crawling or anything so I've never had one tire in the air. When I first bought my Xterra I took it to a gravel lot and stomped the gas a couple times and each time I left TWO markes about 6 feet long indicating both tires were getting power. Also, ever now and then when I get on it in a curve I get a little feel of both tires kicking in.
