Product Information

Land Rover Control Arms and Bushings diagram for Defender 110, Discovery, Range Rover, & more

Control arms are crucial link in a vehicle's suspension connecting the suspension to a vehicle's subframe. These pieces are usually hinged to allow for suspension to travel and articulate as the vehicle rides over obstructions in the road and while the vehicle turns. Many vehicles such as those with independent suspensions have multiple links and feature several connection points and arms to offer better ride quality and comfort.

As bushings and joints in a control arm begin to wear you may notice a looseness feel in your suspension. And while many arms have replaceable and serviceable individual components, many still require the replacement of the entire arm. Below are signs of when a replacement control arm may be needed:

• Play in suspension joints where these arms meet the subframe and/or knuckle
• Buckling noise emanating from the suspension
• Uneven tire wear
• Inability to properly align vehicle
• Shutter or vibration coming from the steering wheel at highway speed
• Wandering or pulling sensation from side to side felt on the steering wheel

About Genuine Land Rover

The same parts Land Rover used to build your vehicle are sold as replacement parts under the “Genuine Land Rover” brand. These are manufactured under Land Rover’s direction, guaranteeing top quality. As you’d expect, they also carry a premium price and are sold exclusively through the Land Rover dealership network.

Genuine Land Rover parts trace their origins back to the earliest days of the brand in 1948, when Rover engineers built the first Series I using robust, serviceable components designed for durability in harsh environments. Over the decades, Land Rover established partnerships with leading European suppliers to ensure consistent quality and performance. This tradition continues today, with Genuine Land Rover parts representing the official replacement components engineered to the same specifications as those used on the production line.

What many owners don’t realize is that Land Rover doesn’t manufacture most of these parts themselves. Instead, they design the components, contract trusted suppliers to produce them, and then verify the quality. Many of these suppliers have partnered with Land Rover for decades. In the industry, they’re known as OEMs (Original Equipment Manufacturers)—brands you probably recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. It’s not unusual to open a Genuine Land Rover box and find one of these brands inside—just re-badged with a Land Rover logo.

On our site, look for OE tags on product pages to quickly spot parts that come straight from the original manufacturers. Choosing these can save you a significant amount compared to buying them in Genuine packaging. For more details on how to identify OE and OEM parts, check out our OE Academy.
