Solution

1. Preparation

Gather tools and materials:
- Floor jack
- Jack stands
- Socket set
- Torque wrench
- Pry bar
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Inspect and Replace Steering and Suspension Components

Step 1: Lift the Vehicle
- Use a floor jack to raise the front of the vehicle and secure it with jack stands.
Step 2: Inspect the CV Joints
- Check the outer CV joints for torn boots or grease leakage. If damaged, replace the CV joint or axle.
Step 3: Check Control Arms and Bushings
- Use a pry bar to test control arm bushings for play. If they are worn, remove the control arms and replace the bushings or the entire control arm as necessary.
Step 4: Examine Steering Rack and Tie Rods
- Inspect the steering rack for any play and ensure tie rods are secure. Replace any damaged parts.
Step 5: Replace Strut Mounts (if necessary)
- Remove the strut assembly from the vehicle and replace the strut mount if it shows signs of wear or damage. Reinstall and torque to manufacturer specifications.
Step 6: Reassemble and Lower Vehicle
- Reinstall any removed components, lower the vehicle, and torque all fasteners to specifications.
