Suspension Strut

Suspension struts are integrated shock absorber and spring assemblies that control wheel movement, absorb road impacts, and maintain tire contact with the road surface. Unlike separate shock absorbers, struts are structural components that support vehicle weight and provide a mounting point for the steering knuckle and brake assembly.

Failing struts cause bouncing over bumps, nose diving during braking, excessive body roll in turns, uneven tire wear patterns, knocking noises over rough roads, and poor steering response. Drivers often notice the vehicle feels floaty or unstable, especially at highway speeds.

Strut assemblies work closely with strut mounts and coil springs to form the complete suspension system. When struts wear out, the upper strut mounts often show signs of deterioration from increased movement and stress. The integrated coil springs may also lose tension over time, though complete strut assemblies include new springs calibrated to restore original ride height and handling characteristics.

Choose complete strut assemblies for easier installation and guaranteed compatibility, or individual struts if springs and mounts are in good condition. OE-quality assemblies include pre-assembled components with proper alignment and torque specifications. Replace struts in pairs on the same axle to maintain balanced handling and prevent premature wear of other suspension components.

How do suspension struts control vehicle movement?

Struts combine a shock absorber with a coil spring mount in a single assembly, dampening suspension movement while supporting vehicle weight. The internal piston and hydraulic fluid control compression and rebound, while the outer housing provides structural support for steering and braking components.

What are the signs suspension struts need replacement?

Excessive bouncing after hitting bumps, nose diving when braking hard, body roll during cornering, clunking noises over rough pavement, uneven tire wear on inside or outside edges, and poor steering stability or wandering at highway speeds.

Should I buy complete strut assemblies or individual struts?

Complete assemblies include pre-assembled struts, springs, and mounts for easier installation and guaranteed compatibility. Individual struts cost less but require spring compression tools and alignment of existing components, making assemblies the preferred choice for most repairs.
