The "lower arm" is a car part called a lower control arm, which is a key component of the suspension system that connects the wheel hub to the vehicle's frame. Its work is to provide stability by controlling the wheel's motion, allowing it to move up and down over bumps while preventing it from moving too far forward, backward, or side-to-side. This function is vital for a smooth ride and proper handling.  Key functions of a lower control arm: Connects the frame to the wheel: It acts as a pivot, attaching the wheel assembly to the vehicle's chassis or frame. Manages wheel movement: It controls the up-and-down movement of the wheel over uneven roads, absorbing shocks from the road surface. Keeps wheel alignment: It helps maintain proper wheel alignment, ensuring the wheel stays in the correct position relative to the rest of the vehicle. This is critical for safe handling and even tire...

Steering rack is to convert the rotational motion of the steering wheel into the linear motion needed to turn the car's wheels. It does this through a rack and pinion system, where a pinion gear on the steering column meshes with a toothed rack bar, which moves side-to-side to steer the wheels via tie rods. Most modern cars use hydraulic or electric power steering to make this process easier for the driver.

Coil plugs, or ignition coils, are essential components that convert the low voltage from a car's battery into the high voltage needed to create a spark. This high-voltage spark is sent to the spark plug, which ignites the fuel-air mixture in the engine's cylinders, creating the power to make the car run.
