Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery for safety.

2. Inspect and Replace Suspended Components

Inspection of Ball Joints
- Using a jack, lift the front of the vehicle and secure it on jack stands.
- Check ball joints for play by attempting to move the wheel in and out.
- If worn, remove the retaining clips and bolts, then replace the ball joints with new ones.
Control Arm Replacement
- If control arms are damaged, unbolt them from the frame and suspension.
- Install new control arms and torque to specifications (consult service manual for exact torque values).

3. Check and Replace CV Joints

Remove the wheel and brake assembly to access the CV joint.
Inspect the CV boot for any tears or grease leakage; if damaged, replace the CV joint.
Use a slide hammer to remove the old joint and install the new one, ensuring proper fitment and securing with the retaining clip.

4. Steering Components Inspection

Check tie rod ends for any signs of wear; if they are loose, replace them.
Remove the tie rods using a socket set, and install new tie rods, tightening them to the specified torque.

5. Wheel Bearing Inspection

Rotate the wheel and listen for any grinding or roughness; if present, the wheel bearing may need replacement.
Remove the wheel, brake caliper, and rotor to access the wheel bearing.
Use a bearing puller to remove the old bearing and install a new one, ensuring it is properly seated.
