Symptoms of Wear
Like most safety-critical chassis components, shocks and struts wear out so gradually over the course of normal operation that the negative effects - reduced steering precision, stopping performance and/or vehicle stability - might not be easily recognized in normal driving conditions. The rate of wear depends on a wide range of variables, such as road and environmental conditions, your driving style and vehicle load.
Why To Replace
It can be easy to overlook the gradual degradation of steering, stopping and stability caused over time by worn ride control components.

DISCUSS THE VEHICLE’S REPAIR HISTORY, THE WAY THE VEHICLE HANDLES AND ITS INTENDED USE.
  • Have the shocks or struts been in service for 50,000 miles / 80,000 kilometres or more?
  • Does the vehicle require repeated replacement of front brakes, suspension components or tires?
  • Has the ride quality changed over time?
  • Is the vehicle used in any of the following ways:
    - Towing
    - Off-road use
    - Consistently loaded
    - Agricultural use
    - Commercial use
    - Upgraded with performance enhancements
    - Consistently driven on unpaved roads

DETERMINE WHETHER THE VEHICLE’S STEERING, STOPPING AND STABILITY ARE COMPROMISED
  • Do small or large road indents (or potholes) seem unusually harsh?
  • Does the vehicle bounce or float excessively?
  • Is the vehicle difficult or stressful to control at highway speeds, during windy conditions or when loaded?
  • Does the vehicle dive, squat, roll or sway rapidly during steering or handling maneuvers?
  • Does the vehicle lack directional stability on rough roads?
  • Does the suspension top or bottom out abruptly?
  • Any excessive or unusual noises from the suspension?

SYMPTOMS OF PHYSICAL WEAR WHICH MAY INDICATE NEW SHOCKS AND STRUTS ARE REQUIRED:
  • Are there any signs of physical damage which could compromise the ride control unit’s ability to function as intended?
  • Is the rod bent, rusted, loose or scratched?
  • Does the air shock have a torn or leaking air boot?
  • Is fluid leaking down the side or o the bottom of the unit?
  • Has corrosion compromised the integrity of any components which make up the shock or strut?
  • Are non-replaceable bushings damaged or missing?
  • Do the vehicle’s tires display cupped, uneven or accelerated tire wear?
  • Is the electronic unit producing a diagnostic code indicating failure?
    NOTE: This may require additional electronic circuit diagnostics
