i wouldnt recommend installing gears unless you really know what your doing. If you do then go for it. Ive heard the trac lok isnt that hard to rebuild. If you have your gears done by a shop it only costs 40 or 50 bucks extra to get your trac lock rebuild. Just something to think about. Good luck whatever you do.
