Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar, and a creeper.
Ensure the vehicle is parked on a level surface and set the parking brake.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle.
Securely place jack stands under the vehicle to ensure stability.
Remove the front wheels for better access to suspension components.

3. Inspect and Replace Components

Shock Absorbers/Struts

Sub-steps:
1. Check for oil leaks around the shock absorber or strut.
2. If damaged, unbolt the top mounting bolts and lower bolts, then remove the strut.
3. Install the new strut in reverse order, ensuring to torque the bolts to manufacturer specifications (typically around 40-50 ft-lbs for top mounts).

Sway Bar Links and Bushings

Sub-steps:
1. Remove the bolts securing the sway bar links to the sway bar and control arms using a socket set.
2. Replace with new sway bar links and bushings, ensuring to torque the bolts as specified (generally about 30-35 ft-lbs).

Control Arms and Bushings

Sub-steps:
1. Inspect control arm bushings for cracks or wear.
2. If replacement is necessary, unbolt the control arm from the chassis and the ball joint.
3. Install the new control arm and torque bolts to specifications (approximately 50-60 ft-lbs).

4. Reassemble and Lower Vehicle

Reinstall the front wheels.
Lower the vehicle off the jack stands.
Tighten lug nuts to the manufacturer’s specifications (usually 76-83 ft-lbs).
