    • When tightening the bolts on the diff plate it is vital that you tighten them in a star pattern to avoid warping the plate. Do not exceed a torque of 40 ft-lbs per bolt.

    • Repeat the last step in reverse to re-tighten the bolts on the differential cover while following the star method of tightening bolts. Use a torque wrench to ensure proper torque specifications.

    • Now the differential is fully sealed and ready for new oil.

    • Re-insert the rubber filler plug.

Don’t forget the clean the old gasket material off, wipe up any differential fluid residue, clean the mating surface with brake cleaner, and add a new gasket maker material.

This guide really left out some very important steps. And don’t reuse your diff fluid people.

No mention of anti-slip additive which is not optional.
