Well........JL showed up about 7:30. Fed him burgers and corn on the cob.
After we got done eating. We started to bust azz and spin wrenches about 8pm. JL did most of the wrenching with me giving directions. Got the diff out. Checked backlash. His was almost .003". Checked ring and pinion tooth pattern. It was good too. Cleaned the inside of the diff. Installed the new Z1 diff cover. The diff is ready to go back in. We called it a night at midnight. Got a lot done in 4 hours.
