Description
The BMW Front Left Caster Arm (Part Number: 31106787673) is a genuine OEM suspension component designed to maintain correct caster angle and front axle stability. It connects the front subframe to the steering knuckle, helping control wheel positioning during acceleration, braking, and cornering.
Engineered to BMW factory specifications, this left-hand (LH) caster arm ensures precise fitment, reduced vibration, and optimal steering response. A worn caster arm or bush can cause clunking noises, steering instability, uneven tyre wear, and poor alignment. Replacing it with an OEM-quality arm restores factory suspension geometry and driving comfort.
