Happy New Year to everyone!!

I was reading the info on these i was wondering if there are lockers for the '99 trooper.

nope - they fit the standard 12 bolt up to 97 in the trooper

the 98+ has what we call a "modified" 12 bolt - simply a Larger differential.

many guys have swapped in a 96 or 97 rear 12 bolt for gear and locker compatibility

??????...OK, now I'm confused. I'm hoping one of you guys with much greater depth of experience can clear this up for me.

I ordered the Aussie Locker for my 99 Vehicross, does that have the same axle as a 99 Trooper?
I found out after I received mine, that I need to get a carrier from an open diff., (all VX's came with LSD) does this mean I'll now have to find a new rear axle too? <img src="/forums/images/graemlins/confused.gif" alt="" />

no just an open carrier 3rd member for your vehicross, not the entire axle. the vehicross used the 'old' 12 bolt w/ the smaller ring gear, and the later troopers used the 'new' 12 bolt w/ the larger ring gear.

Thank You, I was beginning to think this was gonna be WAY more involved than I had first thought.

Anytime you swap in a new carrier, you should really check backlash as well. Just swapping over the shims as they came off of the original carrier may get you within specs; but it would be a costly mistake if it didn't. Too tight can burn things up. Too loose results in too much driveline slop and an increased chance of tearing things up because of shockloading. I would also suggest buying new bearings for the carrier and keeping your originals to use as "set up" bearings so the good bearings don't get chewed up taking them on and off to adjust shim placement.
