Toyota! What's this Crap! Opinions wanted!

What happens here

Fill the rear differential with new SAE 75W-90 Synthetic Gear Oil using a McNaught pump. This specialized pump screws directly onto the gear oil bucket and allows for easy, clean transfer of fluid. Pump the fluid until it begins to overflow from the fill plug opening. Once filled, reinstall the fill plug and tighten it. Repeat the same process for the front differential. Check the underside of the vehicle for any leaks from the drain plugs or filter housing before reinstalling the skid plate.

Goal: Fill differentials with new fluid and ensure no leaks.
