Product Details
✓Twelve washers, enough for two full drivetrain services: 6 steel 12157-10010, 4 aluminum 90430-A0003 and 2 copper 90430-24017. Which goes where on one service — front differential drain plug: 1 copper 90430-24017, 24 mm. Front differential fill plug plus rear differential drain and fill plugs: 3 steel 12157-10010, 18 mm. Transfer case drain and fill plugs: 2 aluminum 90430-A0003, 18 mm. Two copper, six steel, four aluminum.
✓The copper 24 mm washer goes on the front differential only, so it is used on four wheel drive Tacoma, Tundra, 4Runner, Sequoia, FJ Cruiser and Land Cruiser and on Lexus GX, LX and IS, GS and RC AWD — a two wheel drive truck has no front differential. 90430-A0003 replaces 90430-18008. Not for the engine oil drain plug: the engine takes the 12 mm washer 90430-12031, our separate 12 mm Toyota listing.
✓Crush washers are single-use components — Toyota recommends replacing every washer at every differential and transfer case fluid change. Reusing old crush washers is the most common cause of gear oil leaks after service. A differential that slowly loses fluid due to a bad washer can result in gear damage costing thousands. Fresh washers at every service keep your drivetrain sealed and your fluids at the proper level.
✓Manufactured to OEM specifications: steel for durability, aluminum for flexibility on aluminum housings, copper for superior thermal conductivity on transfer case applications. All washers are precision-sized to match factory dimensions for proper crush and sealing performance.
✓Compatible with Toyota Tacoma (2005-2024), Tundra (2000-2024), 4Runner (2003-2024), Sequoia (2001-2024), Highlander (2001-2024), Land Cruiser, FJ Cruiser, GR86, RAV4 AWD; Lexus GX460, GX470, LX470, LX570, LX600, RX AWD, NX AWD Also fits Lexus IS, GS and RC AWD. Consult service manual for torque specs and 75W-85 GL-5 gear oil requirements. Please verify your OEM washer numbers before ordering.
