Im sorry, I new to this, Im in Moreno valley CA, vehicle had 600 miles on it, When i bought it it had 120 miles since then , i have replace the diff. Oil at least 3 times, the first time I removed the oil had a lot of fine metal (dust like)shavings, Before the break I felt the play on it and I attempted to remove it but i had problems loosen up the axel nut on one side and pull the axel from the differential on the other so I refilled the oil and keep driving it, the day of the loss I was driving kind of hard in and out of 4x4 and locking unlocking it, all I heard was I bang like i hit a rock and then notting, (it neutralize on my).i was able to go back to camp on the 4x4 mode so i now the transmission is not the issue, I haven't been able to remove the differential yet to open and inspect the damage.
