How to install Control Arm
Safely raise the vehicle using a jack and support it with jack stands.Disconnect the wheel, any retaining bolts, and detach the control arm.Position the new control arm correctly, secure it with bolts, and torque to specifications.Attach any necessary hardware, such as sway bar links or steering knuckles.Perform a wheel alignment to ensure proper suspension geometry.

Function of Control Arm
The primary function of a Control Arm is to ensure stable and predictable wheel movement by guiding the suspension's geometry. It transmits forces from the road to the vehicle's body, including vertical loads, lateral forces, and torque, while maintaining proper wheel alignment and suspension travel. This helps in providing a smooth ride, optimal handling characteristics, and enhanced stability.

Instruction of Control Arm
Always refer to the vehicle's manual for specific instructions on installing and adjusting the Control Arm. It's crucial to use the correct tools and follow the torque specifications to damage and ensure .
