Solution

1. Preparation

Gather tools: socket set, torque wrench, jack stands, and a pry bar.
Ensure the vehicle is on a flat surface and engaged in park with the parking brake applied.

2. Inspect and Replace Damaged Suspension Components

Lift the Vehicle:
- Use a hydraulic jack to lift the front of the vehicle and secure it with jack stands.
Inspect Control Arms and Ball Joints:
- Use a pry bar to check for play in the ball joints and control arms. If any play is detected, replace the affected component.
- Tools Required: Socket set, torque wrench.
Replace Components (if necessary):
- Remove the nuts/bolts securing the damaged control arm or ball joint.
- Install the new part, ensuring it is torqued to the manufacturer's specifications.
- Torque Values: Refer to the service manual for specific torque specifications.

3. Check and Replace CV Joint or Axle

Inspect CV Joints:
- Examine the outer and inner CV joints for any cracks or damage.
- If damaged, remove the axle assembly.
Replace Axle (if necessary):
- Remove the axle nut using a socket set and pull the axle from the hub.
- Install the new axle and torque the axle nut to the manufacturer's specifications.

4. Verify Power Steering System

Check Fluid Level:
- Inspect the power steering fluid reservoir and top off if low.
Inspect for Leaks:
- Check hoses and connections for any signs of fluid leakage. Replace any damaged hoses.
