Discovery 4 suspension
Coil suspension, steering and chassis parts for Land Rover models, from the live-axle Defender to independent-suspension Range Rovers.
What is specific to the Discovery 4
Suspension layout on the Discovery 4: Permanent four-wheel drive with a two-speed transfer case (from 2014 some markets could have a single-speed unit instead), Terrain Response and all-round height-adjustable air suspension on most vehicles.
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 Discovery 4 air suspension for that side of the system.
Have this ready when you enquire
- The 17-character VIN from your licence document, which identifies your exact L319 (sold here 2009–2017) and its build.
- The exact derivative, for example 3.0 TDV6 HSE, SDV6 S, SDV6 SE and SDV6 HSE, as listed on your licence document.
- Whether the vehicle is on air or steel springs (air suspension is recorded for this model).
- A photo of the old part or its part number, if you can get to it.
Known Discovery 4 suspension faults
Parts commonly needed for the Discovery 4
Front lower arms, anti-roll bar bushes and electronic handbrake actuators follow. Owners planning ahead also order front and rear differential parts and suspension bushes at the same time as a timing belt service, because the vehicle is already in the workshop and labour on this model is expensive.

Discovery 4 suspension questions
Does my Land Rover have air suspension or coil springs?
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.
Why does my Land Rover clunk over bumps?
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.
