Includes: (1) Differential Drain Plug Description: The plugs in the differential can wear over time. Sometimes they end up cross-threaded; other times the fittings end up rounded off. We recommend inspecting both the fill and drain plugs every time you change your differential oil. See Related Items for the sealing washer and the fill plug. Sold individually; one required per car.

This will ensure that you do not end up with an empty differential that you can't refill.
