Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks for added safety.
Wear appropriate safety gear (gloves, safety glasses).

2. Lift the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on which strut you are checking.
Secure the vehicle on jack stands for safety.

3. Remove Wheel

Use a socket set to remove the lug nuts and take off the wheel.
Ensure the wheel is stored safely to avoid damage.

4. Inspect the Strut

Examine the strut for any signs of oil leakage around the seals.
Check the strut boot for tears or damage that could cause fluid loss.
Look at the mounting points and bushings for wear or deterioration.

5. Replace If Necessary

If a leak is confirmed, proceed to replace the strut.
- 5.1. Remove the Strut Assembly
  - Unbolt the strut from the lower control arm and the upper strut mount.
  - Carefully detach any connected components (brake lines, sway bar links).
- 5.2. Install New Strut
  - Position the new strut in place and secure it to the lower control arm and upper mount.
  - Torque the bolts to the manufacturer’s specifications.
- 5.3. Reassemble Components
  - Reattach any disconnected components and ensure they are secure.

6. Reinstall Wheel and Lower Vehicle

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and use the jack to support the weight.
Torque the lug nuts to the manufacturer’s specifications.
