Had the same thing happen to me only it was on the highway at 65MPH. I heard some truckers on the CB talking about "the shower of sparks coming from that truck in the southbound lane." NO one was hurt and I managed to get the Jeep off of the road and on to the shoulder. I had to get a new shaft for that side because the old one was scored too bad. I smelled the gear oil earlier in the day and thought I just had a leak in the diff cover. WRONG! Anyway, check out the thread "Death inviting rear axle" on the board. It had a lot of good info, I just wish I had seen it before it happened to me.
Best of luck,
