For the newbies to 4WD or AWD, those who chose the optional LSD (limited slip differential) in the XS model or the standard in the XT, you should know that LSD doesn't mean you get to floor it and think it will power both wheels equally. You get that at partial throttle while lugging through stuff. It's limited. If you want both those tires spinning the same amount all the time, take it to a welder and have them weld the spider gears, and then by golly you'll have positive traction.
The WOT (wide open throttle) approach is effective in most instances with the X and the XS, but I don't recommend full throttle in 1st and 2nd in the XT, unless you REALLY got a need for wheel speed...and be ready to check your brakes out for stopping power!
Judgment still comes into play with LSD...it's an art you'll have to learn, through mudhole after mudhole, sand dune after sand dune, tankful after tankful,
