The car's lower control arm connects the wheel hub and steering knuckle to the vehicle's frame, bearing most of the suspension weight and controlling wheel motion.• Supports Vehicle Weight: Carries the primary weight of the vehicle and manages structural loads at the front axle.
• Guides Wheel Travel: Allows the wheel to move up and down smoothly when driving over bumps, potholes, or uneven terrain.
• Resists Forces: Constrains the steering knuckle by handling heavy lateral (cornering) and longitudinal (braking and acceleration) forces.
• Maintains Alignment: Keeps the wheels properly aligned to ensure safe steering, handling, and even tire wear.
• Dampens Vibrations: Uses built-in rubber bushings to absorb road noise, vibration, and harshness before they reach the cabin
