Solution

1. Preparation

Gather tools: jack, jack stands, socket set, and torque wrench.
Ensure the vehicle is parked on a level surface, and engage the parking brake.

2. Raise the Vehicle

Use the jack to lift the vehicle from the designated jacking points.
Secure the vehicle with jack stands to ensure safety while working underneath.

3. Remove Shocks

Front Shocks:
1. Remove the wheel using a socket set.
2. Locate the top shock mounting bolts and remove them.
3. Remove the lower shock bolt from the control arm.
Rear Shocks:
1. Remove the rear wheel using a socket set.
2. Remove the top shock mounting bolts from the rear shock tower.
3. Remove the lower shock bolt from the axle.

4. Inspect and Replace

Inspect the removed shocks for signs of wear or damage, such as leaks or bent shafts.
If worn, install the new shock absorbers by reversing the removal steps:
1. Position the new shock in place.
2. Tighten the lower bolt to the manufacturer's specified torque (usually found in the service manual).
3. Secure the top mounting bolts, ensuring they are tightened to the correct specifications.

5. Reassemble and Lower Vehicle

Reattach the wheels and tighten the lug nuts to the manufacturer’s recommended torque.
Carefully remove the jack stands and lower the vehicle back to the ground.

6. Final Check

Perform a final visual inspection to ensure all components are secure.
Test the vehicle again for proper ride quality.
