•Visible oil or fluid stains on the strut assembly
•Unusual noises during bumps or turns (clunking or rattling)
•Excessive body roll or swaying while driving
•Uneven tire wear patterns
•Poor ride quality or a bouncy feeling when driving over uneven surfaces

Diagnostic Steps

1
Inspect strut assemblies visually for any signs of oil or fluid leakage.
2
Check for dampness or residue on the strut shaft and surrounding areas.
3
Perform a bounce test by pushing down on the front or rear of the vehicle and observing the rebound.
4
Examine the undercarriage for any signs of fluid drips or pooling.
5
Look for any signs of rust or corrosion on the strut components that could indicate failure.

Solution

Diagnostic Steps

2
Check for dampness or residue on the strut shaft and surrounding areas.

4

5

Solution

1. Preparation

Gather tools and materials required for inspection.
Ensure the vehicle is parked on a flat surface and the engine is off.

2. Perform Visual Inspection

Use a flashlight to closely inspect both front and rear struts.
Look for any signs of leaking fluid around the strut seals or on the strut body.
Check the dust boots for tears or damage.

3. Conduct a Bounce Test

Stand at the front or rear of the vehicle and apply force downward to compress the suspension.
Release the pressure and observe how the vehicle responds. It should return to its original position without excessive bouncing.
If the vehicle continues to bounce more than once or twice, this may indicate worn or leaking struts.

4. Clean and Mark

If any fluid is found, clean the area around the strut to remove debris and old fluid.
Mark the location with a non-permanent marker to revisit after a short drive to check for new fluid accumulation.

5. Final Assessment

After the vehicle has been driven for a short distance, re-check the previously marked areas for any new fluid presence.
If fluid reappears, the strut may need replacement.
