Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface.
Wear safety gloves and eye protection.

2. Inspect and Replace Suspension Components

Control Arms and Bushings:
- Lift the vehicle using a jack and secure it on jack stands.
- Use a socket set to remove the bolts securing the control arms.
- Inspect the bushings for cracks or wear; replace if necessary.
- Torque new control arm bolts to manufacturer specifications (usually around 60-80 ft-lbs).
Ball Joints:
- Detach the ball joint from the control arm using a ball joint separator tool.
- Inspect for play; if worn, replace with a new ball joint.
- Reinstall and torque the ball joint to specifications.

3. Inspect and Replace CV Joints

CV Joint Inspection:
- Lift the vehicle and remove the front wheel using a lug wrench.
- Examine the CV boot for tears or leaks; replace if damaged.
- If the CV joint is worn, use a 12-point socket to detach the axle from the transmission and replace the CV joint.

4. Examine Steering Components

Tie Rods:
- Check the inner and outer tie rods for play; replace if necessary.
- To replace, use a wrench to disconnect the tie rod end from the steering knuckle and install the new tie rod.
- Torque to manufacturer specifications.

5. Wheel Bearing Inspection

Wheel Bearing Check:
- Spin the wheel by hand to listen for noise; check for play by wiggling the wheel.
- If the bearing is noisy or loose, remove the wheel and hub assembly to replace the bearing.
- Follow the specific torque settings for the bearing nut upon reassembly.
