Building Notes:
• Set gear mesh in differential by tightening all four screws
until diff locks. Then loosen each screw ¼ turn. Diff should
still be hard to turn, but will smooth out after running.

If diff is too loose, the internal gears will quickly ware out

• When tightening the four screws, look for one thread
coming out of diff cover.
