Genuine Bentley Bentayga Front Lower Control Arm with Ball Joint (Left & Right)

Genuine OEM Front Lower Control Arm for the Bentley Bentayga (2016–Present). This high-strength forged aluminum arm comes pre-assembled with the factory-pressed ball joint and hydraulic bushings. There are 2 of these primary lower arms fitted per car (1 per side). Engineered to handle the massive torque and curb weight of the W12 and V8 engines, this arm is the critical foundation for your vehicle's steering geometry and front-end stability.

Restore factory-fresh handling and eliminate "clunking" sounds with the Genuine Bentayga Lower Control Arm assembly.

As the primary pivot point for the front suspension, the lower control arm is subject to extreme stress. Over time, the integrated ball joint develops play and the internal hydraulic bushing can leak or tear, leading to vague steering and uneven tire wear. This Genuine Bentley part (available for both Left and Right sides) is the only way to guarantee the 100% vibration isolation and safety standards originally set by the factory.

Topical Authority Specs:

• Left Side Part Number: 4M0407151 (Check latest suffix, e.g., P/AC).

• Right Side Part Number: 4M0407152 (Check latest suffix).

• Quantity Required: 2 fitted per car (1 Left, 1 Right).

• Components Included: Forged Aluminum Arm, Pre-pressed Ball Joint, and Rearward Hydromount Bushing.

• Compatibility: 2016–2026+ Bentley Bentayga (All Variants), Audi Q7/Q8, Lamborghini Urus.

The Engineering Advantage: Because the ball joint is an integral part of this specific arm's geometry, choosing Genuine OEM ensures the taper fit into the steering knuckle is precise to the micron. This prevents the "death wobble" or high-speed shimmy often associated with lower-quality aftermarket suspension components.

 

Tech Tip:

There are 2 lower control arms fitted per car (one per side). When installing these, the large inner bushing bolt must be tightened only when the vehicle is at its "Normal Ride Height" (wheels on the ground or on a 4-post lift). Torquing this bolt while the suspension is hanging will twist and destroy the new hydraulic bushing within miles
