What Are the Components of Your Suspension?

Understanding Your Vehicle's Suspension System

Your suspension system is complex, with multiple components working together. City Side Auto Body's certified technicians explain each part and its function.

Primary Suspension Components

1. Shock Absorbers

Shocks control spring and suspension movement by:

• Dampening oscillations
• Preventing excessive bouncing
• Maintaining tire contact with road
• Typical lifespan: 50,000-100,000 miles

2. Struts

Struts are structural components that:

• Combine shock absorber and structural support
• Support vehicle weight
• Affect alignment angles
• Critical for steering and handling

3. Springs

Coil Springs

• Most common type
• Support vehicle weight
• Absorb road impacts

Leaf Springs

• Common in trucks and SUVs
• Handle heavy loads
• Simple, durable design

4. Control Arms

Connect suspension to vehicle frame:

• Upper and lower control arms
• Allow vertical wheel movement
• Maintain proper wheel position
• House ball joints and bushings

5. Ball Joints

Pivoting connections that:

• Allow steering movement
• Support vehicle weight
• Enable suspension travel
• Critical safety component

6. Sway Bars (Anti-Roll Bars)

Reduce body roll during turns by:

• Connecting left and right suspension
• Distributing forces evenly
• Improving stability

7. Bushings

Rubber or polyurethane cushions that:

• Reduce noise and vibration
• Allow controlled movement
• Protect metal components

Signs of Suspension Problems

• Uneven tire wear
• Vehicle pulling to one side
• Excessive bouncing
• Nose diving when braking
• Clunking or rattling noises
