Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface.
Use wheel chocks to prevent rolling.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels to access the shock absorbers more easily.

3. Remove Old Shock Absorbers

Tools Required: Socket set, wrench, torque wrench.
Locate the bolts securing the shock absorber to the upper mount and lower control arm.
Remove the bolts using a socket and wrench (note the torque specifications for reinstallation).
Carefully detach the shock absorber from the vehicle.

4. Install New Shock Absorbers

Align the new shock absorber with the mounting points.
Secure the upper mount first, followed by the lower control arm.
Torque Specifications: Refer to the service manual for specific torque values for securing bolts.
Ensure that the shock is properly seated in the mounts.

5. Reassemble and Lower the Vehicle

Reattach the wheels and secure the lug nuts to the correct torque.
Lower the vehicle from the jack stands and remove the jack.

6. Final Inspection

Check the installation to ensure everything is properly secured.
Perform a bounce test once the vehicle is back on the ground to confirm proper function.
