Land Rover Discovery 3 4.4 V8 petrol: underbody & corrosion check

Body & chassis · Discovery 3 (2004–09) · 2004–2009

How often: every year. Subframes, brake pipes and (on the Discovery 3/4 and Sport L320) the steel frame corrode in salty winters.

Work safely: support the vehicle on axle stands, never a jack alone; let it cool first. Check figures against your workshop manual. You do this work at your own risk.

Parts

Cavity wax / underbody protection

Tools

Torch
Pressure washer

Step by step

Wash the underside, then check the subframes, frame rails, brake and fuel pipes, and the rear arches.
Treat any bare metal and re-wax cavities.
