Which front suspension component is a combination spring/damper and is designed for unibody vehicles?

• A. Coil Spring
• B. Torsion Bar
• C. MacPherson Strut
• D. Leaf Spring

Answer: (C)

The front suspension component being described is the MacPherson strut. It combines a coil spring with a damper inside a single, compact unit, and the strut itself acts as a structural member attached to the wheel hub and the vehicle body. This integrated design is ideal for unibody vehicles because it reduces parts count, saves space, and provides a straightforward mounting point for steering while still handling load from the wheel.

Coil springs by themselves lack damping, so they can’t control wheel motion without a separate shock absorber. A torsion bar is a spring that works with different setups and typically doesn’t provide an integrated damper in the same unit. Leaf springs are a different style of suspension not typically used as the front unibody spring/damper assembly.
