Shock absorbers dampen the shock the suspension absorbs when the vehicle is driven over an uneven road surface. There is a shock absorber at each wheel.

MacPherson strut–type front suspensions use an upper suspension strut bearing on top of each front suspension. The wheels are attached to the suspension at each corner of the vehicle.

The front suspension strut dampens movement as a vehicle is driven over rough or uneven road surfaces. A vehicle with strut-style suspension has a suspension strut assembly at each wheel, which needs to be replaced if the strut leaks oil or no longer has a dampening effect.

The sway bar (or anti-roll bar) helps reduce vehicle lean during cornering. The center of the sway bar is attached to the chassis, and the ends of the sway bar are attached to the left and right front suspension.

The thermostat is a valve that keeps coolant circulating in the engine until it reaches normal running temperature. When this happens, the thermostat opens and allows coolant to flow to the radiator.

On a vehicle with rack and pinion steering, there is an inner tie rod end at each end of the steering rack. When the driver turns the steering wheel, the steering rack either pushes or pulls the front wheels.

Internal engine components are lubricated with oil. Engines have many seals and gaskets that prevent oil from leaking out of the engine.

The water pump pushes coolant through a vehicle's cooling system. The water pump is operated by a fan belt at the front of the engine or by the timing belt.

Wheel bearings allow each wheel to rotate. There are several types of wheel bearings used in cars: some require no maintenance; others can be disassembled, cleaned, and inspected for wear.

An antilock brake wheel speed sensor measures the speed of each wheel by counting the number of revolutions each wheel makes while braking to be sure the wheel isn't locking up. If a wheel locks up, the antilock brake control module can apply or release brake fluid pressure to each wheel, releasing the wheel from its locked state.

If a wheel locks up, the antilock brake control module can apply or release brake fluid pressure to each wheel, releasing the wheel from its locked state.
The antilock brake control module counts the number of revolutions each wheel makes to determine whether the brake at each wheel is operating correctly or if it has locked up. If the brakes lock up, the antilock brake control unit releases the brake pressure applied to each wheel until the unit determines whether each wheel is contributing the correct amount of braking effort.

If the driver feels vibration in the brake pedal while braking, it may indicate that the brake drums need to be re-machined or replaced. .
