Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery for safety.

2. Inspect and Replace Suspension Components

Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheel to access the suspension components.
3. Inspect control arm bushings and ball joints for wear. If damaged, replace them using a socket set.
4. If any bushings are worn, remove the old bushing using a bushing removal tool and install the new bushing.
5. Reattach the control arms and torque to manufacturer specifications.

3. Check and Refill Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir and remove the cap.
2. Check the fluid level; if low, add the correct type of power steering fluid as specified in the owner's manual.
3. Inspect the power steering lines and connections for any signs of leaks and replace any damaged components.

4. Inspect and Replace CV Joints

Sub-steps:
1. With the vehicle still lifted, inspect the CV joints for cracks or tears in the boot.
2. If damaged, remove the axle using a socket set, then replace the CV joint or the entire axle assembly.
3. Install the new axle and torque all bolts to specifications.

5. Final Reassembly

Sub-steps:
1. Reinstall the wheel and lower the vehicle.
2. Reconnect the battery.
3. Perform a final check of all fasteners and components to ensure everything is secure.
