Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Suspension Components

Inspect Control Arms and Bushings:
- Remove the front wheels using a socket set.
- Visually inspect control arms and bushings for cracks or wear.
- If damaged, proceed to replace the control arms and bushings.
Replacement Steps:
- Use a ball joint separator to disconnect the control arm from the knuckle.
- Unbolt the control arm from the chassis.
- Install the new control arm and torque bolts to manufacturer specifications (typically around 60-80 Nm).
- Reattach the wheel and lower the vehicle.

3. Check Power Steering System

Inspect Power Steering Fluid:
- Check the fluid reservoir for the power steering fluid level.
- If low, top up with the appropriate fluid (usually ATF or specific PS fluid).
Inspect for Leaks:
- Look for leaks around the steering rack and hoses.
- If leaks are found, replace the affected hoses or the steering rack as needed.

4. Inspect CV Joints and Axles

Check CV Joints:
- With the vehicle lifted, rotate the wheels and listen for clicking noises.
- If clicking is heard, replace the affected CV joint or axle.
Replacement Steps:
- Remove the wheel and brake assembly to access the axle.
- Use a socket set to remove the axle nut and disconnect the axle from the hub.
- Install the new axle, ensuring it is properly seated in the transmission.
- Reassemble components and torque the axle nut to manufacturer specifications (typically around 200 Nm).
