Symptoms & Diagnosis

Warning Signs of a Failing Strut with Coil Spring

  • Bouncy or unstable ride
  • Excessive leaning when turning
  • Nose diving when braking
  • Uneven tire wear
  • Clunking or rattling noises from the suspension
  • Visible damage to the strut, such as leaks or corrosion

Testing the Strut with Coil Spring

  1. Bounce Test: Push down firmly on the corner of the vehicle above the strut. Release quickly. The vehicle should rebound once and settle. Excessive bouncing indicates a worn strut.
  2. Visual Inspection: Look for signs of leaking fluid, rust, or physical damage to the strut body, coil spring, and mounting points.
  3. Road Test: Drive the vehicle over bumps and listen for unusual noises. Pay attention to how the vehicle handles during turns and braking.

Common Failure Causes

  • Normal wear and tear over time
  • Damage from potholes or road debris
  • Corrosion due to exposure to salt and moisture
  • Leaking hydraulic fluid, reducing damping ability
  • Worn or broken coil spring
