BMW X5 E70 X6 E71 Front Left Lower Rearward Control Arm 31126771893

No. The BMW E70/E71 front suspension utilizes two lower control arms per side. The forward curved arm with the large fluid-filled hydro-bushing is the tension strut. This specific part (31126771893) is the rearward, straight track arm.

Highly Recommended. If the rubber bushing or ball joint on your left arm has failed from age and stress, the right side (part number 31126771894) has endured the exact same mileage, massive vehicle weight, and punishing road conditions. Replacing both lower rearward arms simultaneously ensures your suspension geometry remains perfectly balanced.

Absolutely. Anytime you replace a primary structural component of your front suspension, the vehicle's toe and camber geometry will drastically shift. To prevent your expensive tires from wearing unevenly and to ensure your steering angle sensors track perfectly straight, a professional alignment is mandatory immediately after installation.
