This is a great running 2WD fj cruiser and it does have a rear differential locker! All service is current and runs and drives smooth at all speeds. The only issues are at higher speeds there is a very very slight noise on deceleration that I was told could eventually be a rear differential, I see them with warranty for$600-$700.( I wouldn’t be concerned to drive it) eventually if it gets louder it may need replacement. The only other issue os the molding above the windshield needs replacement ( in photos) and The body is in good condition with a few scratches here and there and some slight fading from age , the hood does have paint missing from a clear bra that took the paint off when removed. The interior is in good condition and everything works as it should. Clean title ready to go !
