Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Torque wrench
- Socket set
- Pry bar
- Creeper (optional)
Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Lift the Vehicle

Use the jack to lift the front or rear of the vehicle, depending on which strut you are inspecting.
Secure the vehicle with jack stands.

3. Inspect the Strut Assembly

Visual Check:
- Inspect the strut for any signs of oil leakage; a wet or oily appearance indicates a failed seal.
- Look for dents, rust, or any physical damage to the strut body.
Mounting Points:
- Check that the strut is securely mounted to the vehicle and that no bolts are loose or missing.
- Examine the upper strut mount for signs of wear or cracking.

4. Perform a Bounce Test

Push down on the front or rear of the vehicle sharply and release.
Observe how many times the vehicle bounces; it should settle quickly with minimal bouncing.

5. Check for Play in the Strut Assembly

Use a pry bar to gently pry at the strut assembly to check for movement.
If excessive play is present, the strut may need to be replaced.

6. Reassemble and Lower the Vehicle

Ensure all components are securely fastened.
Remove jack stands and lower the vehicle carefully.
