Frequently asked questions

What is the LT230 high/low gear nut for?

This nut retains the high/low range gear on the LT230 transfer box mainshaft, clamping it against the shaft shoulder to set and hold the gear's axial position. It's torqued to the specified figure on assembly and renewed when the gear is removed.

Which vehicles does this transfer box nut fit?

This high/low gear nut fits the LT230 transfer box used on the Defender (2007-2016, from VIN 7A000001) and Discovery 2 (1998-2004). Because it's specific to the LT230, check that your vehicle has this transfer box before ordering.

Does this gear nut need replacing every time?

Yes, this retaining nut is normally replaced rather than refitted once the high/low gear has been disturbed. Nuts in this position are typically staked or set to a specific torque, so a fresh nut is best for a reliable clamp. Torque to the workshop manual figure.
