STRUTS AND SHOCKS

What they are

• Shocks (shock absorbers): Hydraulic dampers that control the bounce of your vehicle’s springs, keeping tires in contact with the road and smoothing ride quality.

• Struts: A structural component that combines a shock absorber with suspension-supporting elements (spring perch, bearing, sometimes steering pivot). Struts contribute to vehicle alignment and steering geometry as well as damping.

Why they matter

• Safety: Worn dampers reduce tire contact with the road during cornering and braking, increasing stopping distances and loss of control risk.

• Handling & comfort: Faulty shocks or struts cause body roll, nose dive, excessive bounce, and a harsh, unsettled ride.

• Tire life: Poor damping leads to uneven tire wear (cupping or feathering), shortening tire lifespan.

• Suspension components: Struts support other parts (springs, mounts, bearings). Failure can stress mounts, control arms, and steering parts.

Common signs they need service

• Excessive bouncing after hitting a bump

• Nose dive when braking or rear squat on acceleration

• Increased body roll during turns

• Uneven or rapid tire wear

• Fluid leaking from the shock/strut

• Unusual noises (clunking, knocking) over bumps

• Vehicle pulls to one side or steering feels vague

Inspection & diagnosis

• Visual check for leaks, broken mounts, and damaged boots

• Bounce test: push down on a corner—one or two bounces indicates worn dampers

• Road test to evaluate handling, noise, and brake dive

• Tire inspection for uneven wear patterns

• Alignment check after strut replacement

Replacement guidance

• Replace in pairs (both front or both rear) for balanced handling

• Many manufacturers recommend replacing shocks/struts every 50,000–100,000 miles depending on driving conditions; inspect earlier if you drive on rough roads or carry heavy loads regularly

• Strut assemblies vs. rebuilds: Complete strut assemblies (cartridge pre-assembled with spring and mount) save labor and ensure proper
