I swear I tried searching for this 10 different ways... only thing that came up was that "how much should it cost" post, I know it's come up recently. just frustrating, that's all.. Ok, so we're repacking my rear bearings on Saturday, all is well, but when I go to reinsert the axle on the short side (passenger's) it won't go in! Stops about 5" from where it needs to be, so wasn't even up to the splines in the diff yet. Few others give it a try, same result.. get the flashlight. Inside there's this gear that has fallen down, fallen about an inch.... no way the axle is going to slide through it. wtf? So after some head scratching, Jeff comes back with a long spare tire lowering tool, sticks it in there, then somehow wiggles that gear back up, it stays put long enough to get the axle in... whew! bolt that sucker on, quick! For about 30 minutes there we all had visions of pulling the 3rd member, to align that gear by hand, since FF axles don't have inspection covers. So is that the gear that the locker moves when it engages? And the rest of the time, it's just idling on top of the axle, not engaged with anything? Should I have engaged the locker before pulling anything apart? All seems fine now, though I haven't turned the locker on to make sure it's working.. probably worth doing though. Did the whole job a lot like the writeup here (thanks go out to Klunky Chris!) http://22.214.171.124/fzj80_rear_bearing.htm but didn't see anything in there about engaging the locker. I look forward to your comments.
