Frequently asked questions

What is the High/Low Gear Retaining Nut and what does it do?

The High/Low Gear Retaining Nut secures the high/low range gear on the LT230 transfer box mainshaft. It holds the gear against the shaft shoulder to set and maintain its axial position, and is tightened to the specified torque on assembly.

Which vehicles does this LT230 retaining nut fit?

This fits the LT230 transfer box high/low gear on the Land Rover Defender 2007-2016 (from VIN 7A000001) and Discovery 2 (1998-2004). Confirm you have the LT230 box and, for the Defender, check your VIN is at or after 7A000001 before ordering.

Should this nut be reused or replaced?

Replace this retaining nut rather than reusing it. It's typically renewed whenever the high/low gear is disturbed, as retaining nuts of this type can lose their clamping security once removed. Tighten the new nut to the workshop manual torque on reassembly.
