How do you change ring pinion and bearing 1997z71?

To change the ring and pinion gears and bearings on a 1997 Z71, first, safely lift the vehicle and remove the rear differential cover to drain the fluid. Then, remove the differential carrier and unbolt the ring gear from the carrier. Replace the old bearings and pinion gear with new ones, ensuring proper alignment and spacing, and reassemble the differential with a new gasket and fluid. Finally, check the backlash and gear pattern to ensure proper installation before reattaching the differential cover.
