Which part of the suspension system helps maintain alignment of the wheels?

The tie rod plays a crucial role in the alignment of the wheels in the suspension system. It connects the steering rack to the steering knuckle, which ultimately controls the direction of the vehicle’s wheels. When the driver turns the steering wheel, the tie rods transmit the motion of the steering gear to the wheels, allowing for accurate steering response.

Moreover, the tie rods also help to maintain the proper toe alignment of the wheels. Proper toe alignment is essential for even tire wear and overall vehicle stability while driving. If the tie rods are worn or damaged, they can lead to misalignment, which can cause the vehicle to handle poorly, increase tire wear, and affect safety.

In contrast, other components like the control arm provides support for the suspension and helps manage wheel motion but does not directly affect wheel alignment in the same way. Shock absorbers primarily serve to dampen the oscillations of the suspension system to maintain ride comfort, while the steering knuckle connects various components, but it is the tie rod that directly supports wheel alignment and steering response. Thus, it is clear that the tie rod is the key component for maintaining the alignment of the wheels.
