Shocks and struts are essential for driving comfort, especially during summer heat. High temperatures put the suspension system under strain, exacerbating pre-existing issues. Discover how heat affects your shock absorbers and learn to identify signs of wear before they worsen.
Signs of Suspension Wear in Hot Weather
-
Uneven Tire Wear: Heat expands pavement and creates uneven surfaces. Asymmetric wear on your tires may reveal a suspension defect.
-
Excessive Bouncing: On bumpy roads, prolonged oscillations or a bouncy ride often indicate worn shock absorbers.
-
Suspicious Noises: Clunking or knocking sounds from the wheels signal loose or damaged suspension components.
-
Imprecise Steering: A failing suspension affects handling. If the steering wheel feels vague or less responsive, have your system checked.
-
Vehicle Sagging: One side sitting lower than the others typically indicates a faulty shock absorber or strut at that corner.
Summer Maintenance Tips
-
Regular Inspections: Periodic professional checks help detect component wear before failure occurs.
-
Proper Tire Inflation: Correct pressure preserves suspension and improves road handling.
-
Component Cleaning: Prevent buildup of dirt and debris that accelerates wear on moving parts.
-
Preventive Driving: Reduce speed on rough roads and avoid potholes to protect your suspension.
-
Reasonable Loading: Never exceed maximum load capacity to prevent premature wear.
Impact of Heat on Components
Summer heat particularly affects the suspension system. High temperatures soften rubber bushings and reduce the effectiveness of hydraulic fluids in shock absorbers. Overheated roads become more abrasive, accelerating wear on already weakened parts. These extreme conditions quickly reveal weaknesses in an aging suspension.
Preventive Diagnosis
Regularly perform the bounce test: press down with all your weight on each corner of the vehicle then release. If the car oscillates more than twice before stabilizing, your shock absorbers likely need thorough inspection. Also visually inspect struts for potential oil leaks, which are particularly critical during heatwaves.
