Coil suspension, steering and chassis parts for Land Rover models, from the live-axle Defender to independent-suspension Range Rovers.
Suspension layout on the Range Rover Sport (L320): Permanent four-wheel drive with Terrain Response and air suspension, built on the Discovery 3 and 4 integrated body-frame.
Where air suspension is fitted, the springs, compressor, valve block and height sensors are covered separately under air suspension. This page is for the arms, bushes, dampers and other conventional suspension parts.
See Range Rover Sport (L320) air suspension for that side of the system.
Front lower suspension arms, hub bearings and the front differential all appear on specialist common-fault lists for the L320.
Parts commonly needed on the Range Rover Sport L320 include air suspension parts, front lower arms and anti-roll bar bushes, hub bearings, brake discs and pads, and electronic handbrake parts. When one front lower arm or anti-roll bar bush is worn, the other side is usually close behind, so many owners order both sides and a wheel alignment together to avoid paying for the same labour twice.
Discovery 3, Discovery 4, Range Rover Sport and full-size Range Rovers from the L322 onwards mostly use air suspension, and you will see ride height controls on the dashboard or centre console. Classic Defenders, Discovery 1 and most Freelanders, Evoques and Discovery Sports use coil springs. Some models, including the Discovery 2, Discovery 5, Velar and new Defender, were offered with either depending on version. Check the VIN or look for air springs at the wheels.
Worn anti-roll bar drop links, bushes and ball joints are the most common causes. On coil-sprung Defenders and Discoverys, check radius arm and Panhard rod bushes. On Discovery 3 and 4, front lower arm bushes are a common wear point. A workshop can pinpoint it with the vehicle on a lift.
For how these parts work and the signs of wear, read the Land Rover suspension guide.
