Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles for protection.

2. Raise the Vehicle

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

3. Inspect and Replace Suspension Components

Control Arms and Bushings:
- Remove the wheel to access the control arms.
- Inspect bushings for cracks or wear; replace if necessary.
- Use a socket set to unbolt the control arms and replace them.
- Torque bolts to manufacturer specifications (typically around 50-80 ft-lbs).
Struts:
- If struts are suspected, remove them by unbolting the top and bottom mounts.
- Replace with new struts, ensuring proper alignment and torque.

4. Check and Replace Steering Components

Tie Rod Ends:
- Inspect tie rod ends for play by moving them back and forth.
- If worn, remove the cotter pin and nut, and disconnect the tie rod end from the steering knuckle.
- Install a new tie rod end and torque the nut to specifications (usually around 45-55 ft-lbs).

5. Inspect CV Joints

Check the CV boots for tears or leaks.
If damaged, remove the CV joint by unbolting it from the transmission and wheel hub.
Replace with a new CV joint assembly, ensuring proper fitment and torque.
