Front Regear pt3
Use a pipe wrench to hold the pinion in place and crank down the nut to specs in documentation that came with the gears
Install the carrier
Make sure the markings line up correctly
Mark a small section of the gears with marking compound
Rotate the carrier with your hand so the pinion can mark it. Make sure you mark it going in both directions. I ran it back and forth across the pinion three or four times to get the most accurate marking
