STC4379 Front Output Flange Kit Discovery II (L318)

Replace a worn or leaking transfer case front output flange with STC4379, a direct-fit front output flange kit for Land Rover Discovery Series II (L318, 1999–2004) equipped with the LT230 transfer case.

This flange sits at the front output of the transfer case where the front driveshaft connects. Over time the sealing surface can wear or develop grooves, which can lead to transfer case oil leaks or vibration in the driveline. Replacing the flange restores a proper sealing surface for the output seal and ensures a secure mounting point for the front prop shaft.

This part fits Discovery Series II (L318, 1999–2004) models equipped with the LT230 transfer case. Always verify your transfer case configuration before ordering, particularly on vehicles that may have had drivetrain swaps or previous modifications.
