Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery for safety.

2. Inspect and Replace Steering Components

Sub-steps:
1. Remove the wheel to access the steering components.
2. Inspect tie rods for play; replace if worn.
3. Check ball joints for excessive movement; replace if necessary.
4. Reassemble the wheel and torque the lug nuts to the manufacturer's specification (typically 80-100 ft-lbs).

3. Inspect and Replace Suspension Components

Sub-steps:
1. Lower the vehicle and check for any visible wear on control arms and bushings.
2. Replace any worn bushings using a bushing removal tool.
3. Reinstall components and torque bolts to the specified torque values (usually around 40-60 ft-lbs for bushings).

4. Examine CV Joints and Axles

Sub-steps:
1. Inspect the CV joints for any tears in the protective boot.
2. If damage is found, remove the axle from the hub and replace the CV joint or the entire axle assembly.
3. Reinstall the axle, ensuring proper alignment and torque to manufacturer specifications (typically 150-180 ft-lbs for axle nut).
