I did a quick search and found this;
"Lunchbox Locker - A "Lunchbox" locker (or drop-in locker) is a locker mechanism that is designed to fit into the stock differential carrier replacing the spider gear set and sometimes the side gears and pinion-shaft. The nickname "Lunchbox" comes from the idea of packing your lunch in a reusable "lunchbox" where you use the same "lunchbox" and pack in a different lunch. The stock carrier is the equivalent of the "lunchbox". "
Funny thing was I also was wondering what the term ment.

No problem.
You should be fine. What kind of noise did you hear right before you looked at the axle? How bad is the leak?

When its turned to the right even a little theres a maybe grinding noice, and later I think it was also to the left. I drove 2hours away to get a new bumper and I noticed it on the way home. Leak goes all the way to the bottom of the diff its not dripping though
im working on a 97 which recently developed a problem with the radio which led to someone (brother) hitting the radio quite hard. soon after, the speedometer stopped working and the transmission is very confused on which gear to select. the speedometer jumps around quite a lot, no real relation to speed except it will tend to be 0 when stopped and bounce less at lower speeds. transmission will downshift at speed without pressing the gas. any ideas? seems to me like it would be related to the tach wire but beyond that i dont know. if you have a clue please be detailed, this is my gf's car and i havent been around it long
I just fixed my speedometer /tach/ odometer and interior light problems as they stopped working when I installed a new radio and did not connect a wire to 12v positive. It was a yellow wire coming off the harness from the jeep part of the harness. When I re-attached it to the red (hot wires) and the yellow fused wire off the radio, Viola! they came back. (99 Cherokee Sport) When I was researching on this forum I found that much of the electrical system bugs reported had issues that crossed seemingly unconnected systems. You might try making sure you just do not have a loose wire in the radio harness.

Sounds like something is too close inside the carrier. Take it back to that mech. as soon as you possibly can. The leak should be fine for now.
