Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, wrench set, torque wrench, screwdriver, oil catch pan.
Safely lift the vehicle using a jack and secure it on jack stands.
Ensure the vehicle is on a level surface and the engine is turned off.

2. Remove the Shock Absorber

Sub-steps:
1. Remove the wheel where the leaking shock absorber is located.
2. Locate the upper and lower mounting bolts of the shock absorber.
3. Use the appropriate socket to remove the upper bolt first, followed by the lower bolt.
4. Carefully pull the shock absorber out from its mountings.

3. Inspect and Replace

Sub-steps:
1. Inspect the old shock absorber for signs of damage beyond leakage (dents, corrosion).
2. Compare the old shock with the new replacement part to ensure compatibility.
3. If any mounting hardware is worn, replace it with new components.
4. Install the new shock absorber by aligning it with the mounting points.

4. Reassemble

Sub-steps:
1. Secure the upper mounting bolt first, ensuring it is tightened to the manufacturer's specifications (typically around 30-40 lb-ft).
2. Install the lower mounting bolt and torque it to the specified value (also around 30-40 lb-ft).
3. Reattach the wheel and tighten the lug nuts in a star pattern to the recommended torque (usually 75-85 lb-ft).

5. Final Checks

Lower the vehicle from jack stands.
Perform a bounce test again to ensure proper installation and function.
Check for any fluid leaks around the new shock absorber.
