Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Lift the vehicle using a jack and secure it with jack stands.

2. Remove the Old Shock Absorbers

Sub-steps:
1. Remove the wheel corresponding to the shock absorber you are replacing using a lug wrench.
2. Locate the upper and lower mounting bolts of the shock absorber.
3. Use a socket wrench to remove the lower mounting bolt.
4. Remove the upper mounting bolts using the appropriate socket size. Keep the nuts for reuse if they are in good condition.

3. Inspect and Install New Shock Absorbers

Sub-steps:
1. Compare the old shock absorber with the new one to ensure it is the correct part.
2. Position the new shock absorber in place of the old one.
3. Insert and hand-tighten the upper mounting bolts first.
4. Install the lower mounting bolt and torque it to the manufacturer's specifications (typically between 30-50 ft-lbs, check service manual for exact torque).
5. Tighten the upper mounting bolts to the specified torque value.

4. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands and remove the jack.
3. Torque the lug nuts to the specified value (usually around 80-100 ft-lbs).
4. Repeat the process for the other side if replacing both shock absorbers.
