Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, and a pry bar.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working.

2. Lift the Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Ensure the vehicle is stable before proceeding.

3. Remove the Old Shock Absorbers

Front Shock Absorbers:
1. Remove the wheel to gain access to the shock assembly.
2. Unbolt the top mounting nut from the shock tower using a socket wrench.
3. Remove the lower bolt securing the shock absorber to the suspension arm.
4. Carefully pull the shock absorber out of the mounting brackets.
Rear Shock Absorbers:
1. Access the rear shock absorbers by removing the wheel if necessary.
2. Unbolt the top mounting nut and lower bolt securing the shock absorber in place.
3. Remove the shock absorber from the vehicle.

4. Install the New Shock Absorbers

For Both Front and Rear:
1. Position the new shock absorber into the mounting brackets.
2. Insert and hand-tighten the lower bolt and top nut.
3. Use a torque wrench to tighten the bolts to the manufacturer's specifications (typically around 35-45 ft-lbs for lower bolts and 18-22 ft-lbs for upper nuts, but verify with service manual).

5. Reassemble and Lower the Vehicle

Reinstall the wheels and lower the vehicle back to the ground.
Reconnect the battery.
