Solution

1. Preparation

Tools Required: Jack, jack stands, tire iron, flashlight, and a torque wrench.
Ensure the vehicle is parked on a level surface.
Set the parking brake and wear safety goggles.

2. Lift the Vehicle

Use a jack to raise the front or rear of the vehicle as needed.
Secure the vehicle on jack stands for safety.

3. Conduct a Visual Inspection

Use a flashlight to inspect the strut assembly for any signs of damage, such as dents or rust.
Look for fluid leaks around the strut body and seals.

4. Perform the Bounce Test

Stand at a corner of the vehicle and push down hard on the bumper.
Release and observe. The vehicle should rebound and settle quickly without excessive bouncing.

5. Inspect for Noise and Movement

While the vehicle is lifted, manually press the strut to check for any irregular movements or sounds.
Move the wheel side to side to check for play in the strut mount or any abnormal sounds.

6. Recheck Tire Condition

Inspect the tires for uneven wear patterns, indicating potential strut problems.
Make note of any significant wear that may need addressing.
