This thing used to be in rear of my parents TJ quite a long time ago. Always had issues it either not unlocking, or locking, popping, etc. Even after a replacement cover / shift fork, etc.
Anyways, it was replaced in favor of an ARB and it's been sitting in my dads shed for quite a while. I brought it home thinking about tearing into and maybe selling it if it were in good shape. I'm definitely not gonna sell it now!
I remember watching how this thing worked back in the day when they introduced it, but I remember it being a tad different than this.
Anyways, the locker is always "locked" when the collar isn't engaged. The collar just keeps a thin retainer from binding and causing the roll pins to bind up on the outer helical gear. So basically it's a friction based locker. When the collar isn't engaged the thin roll pin collar binds up. Pretty interesting. I thought for sure this was going to be the issue with it. Turns out it was working perfectly.
left to right: outer 'shift' collar; raising the helical gear out to see the bind pins; bind pins!
Next I decided to look at the worm gears inside since that part looked decent, aside from some unusual wear on the outer helical gear...
What's this crap?
Needless to say, I'm at a loss on this. I can't tell if this is damage from sub-par material and impurities or what. Each photo is a different worm gear I pulled out. The damage is in the same spots on each gear!
What do you guys think caused it?
I have a pretty sweet paper weight here. Maybe I'll make a lamp out of it haha.
