xGenuine Bentley Control Arm 3W0407151B - Front Left Lower
The Genuine Bentley Control Arm 3W0407151B restores steering precision to your Continental or Flying Spur. This front left lower control arm is the link between the front subframe and the wheel hub, and when its bushes and ball joint wear, the front end feels vague and tyres wear unevenly. The OE arm delivers exact factory geometry and correct bush stiffness, bolting straight on with no shimming, no guesswork, and no compromised handling on a car built to this standard.
What the Front Left Lower Control Arm Does
The front left lower control arm anchors the bottom of the left front wheel hub to the subframe, controlling camber and toe as the suspension moves. Its inner bushes absorb fore-aft and lateral loads while the outer ball joint allows the wheel to steer and articulate. On a heavy car like the Continental or Flying Spur, this arm carries significant cornering and braking forces, so every dimension — bush position, ball joint centre, mounting geometry — must match the factory design for the suspension to behave as Bentley intended.
Signs Your Control Arm Needs Replacing
A worn front lower control arm usually announces itself through the steering. Common signs include a vague or wandering feel at speed, a clunk or knock from the front left over bumps, uneven or accelerated wear on the front tyres, and the car pulling slightly to one side. The steering wheel may also sit off-centre after the alignment drifts. These symptoms develop gradually as the bushes soften and the ball joint gains play, so drivers often adapt without realising how much precision they have lost.
Why Genuine Matters for a Control Arm
A control arm sets the geometry of the entire front corner, so small deviations have large effects. The genuine 3W0407151B is made to Bentley's original specification: the aluminium arm matches the factory weight and stiffness, the bushes are compounded to the correct durometer for the car's mass, and the ball joint is built to OE tolerances. Aftermarket copies frequently miss on bush stiffness or ball joint centre position, which shows up as imprecise steering, faster tyre wear, or a harsher ride. With the genuine arm, the suspension behaves exactly as the chassis engineers calibrated it.
Fitting Notes for Your Technician
Control arm replacement is a workshop job. The wheel, undertray, and related fasteners come off, the old arm is unbolted from the subframe and hub, and the new genuine arm is fitted with hardware torqued to the manufacturer's specification. A four-wheel alignment is essential afterwards, since the new bushes and ball joint reset the corner geometry. Many technicians recommend inspecting the matching right-side arm and the upper arms at the same time, as they share the same mileage and load history.

FAQs
xFrequently Asked Questions
The 3W0407151B is the front left lower control arm for Bentley Continental and Flying Spur models. It anchors the left front wheel hub to the subframe, controlling camber and toe as the suspension moves. Inner bushes absorb fore-aft and lateral loads while the outer ball joint lets the wheel steer and articulate, keeping the corner geometry as Bentley designed it.
Watch for vague or wandering steering at speed, a clunk from front left over bumps, uneven front tyre wear, the car pulling to one side, or a steering wheel sitting off-centre. These signs develop gradually as bushes soften and the ball joint gains play. A technician can confirm wear on a lift by checking for arm movement and joint play.
The 3W0407151B is listed for the front left lower position on Bentley Continental GT, Continental GTC, and Flying Spur models on the 3W chassis. However, control arms and their supersessions vary across model years, and left and right arms are not interchangeable. Send us your full VIN before ordering so our team can confirm the exact application for your car.
A control arm sets the geometry of the whole front corner, so small errors have large effects. The genuine 3W0407151B matches factory bush positions, ball joint centre, and bush stiffness, keeping steering precise and tyre wear even. Aftermarket copies often miss on stiffness or joint position, leading to vague steering or faster tyre wear that costs more long-term.
This is a genuine Bentley part in factory packaging, covered against manufacturing defects under the genuine parts warranty, and your statutory consumer rights apply in the UAE. If the part arrives damaged or incorrect due to our error, we will replace or refund it. We verify your VIN before dispatch so you receive the correct arm for your 3W variant.
