Oh, you're right. Guess I read it online somewhere and believed it... I just did a quick online look and can't find any LXs with rear lockers in 98 or 99.
It confused the heck out of me too. Supposedly 98-99 Canadian LX's had the rear locker and no LSD option (though that is even up for debate on the good old iGoogle). I originally looked for a rear locked 100 series (LC or LX). Couldn't find any down here in TX. I "settled" on a gently used '98 LX with the LSD and 2 pinion diff. I was initially concerned that it would be limited in offroad capability because of those two things. I was WAY wrong in that assumption. I'm sure I could find situations where a locker and 4-pinion front diff would be valuable, but I've yet to encounter that. From my racing background, I have a solid concept of left foot braking, heel-toe and throttle management. The 2 pinion diff's that "blow-up" seem to be related to people recklessly overthrottling when a front wheel is lifted, then comes down and grabs dirt which "shocks" the diff that then implodes.
