Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.

2. Inspect and Replace Power Steering Fluid

Remove the power steering fluid reservoir cap.
Check the fluid level; if low, top up with the manufacturer-recommended fluid.
If the fluid is discolored or contaminated, perform a fluid flush and replace with new fluid.

3. Inspect CV Joints and Replace if Necessary

Safely lift and support the front of the vehicle using jack stands.
Remove the front wheel on the side where the noise is heard.
Inspect the CV joint and boot for any tears or grease leakage.
If damage is found, remove the axle nut using a socket and ratchet, disconnect the lower control arm to free the axle, and replace the CV joint or axle as needed.
Reinstall everything in reverse order, ensuring to torque the axle nut to manufacturer specifications.

4. Inspect Suspension Components

With the vehicle still lifted, visually inspect the struts, control arms, and bushings for signs of wear or damage.
If any components are found to be damaged, remove them using a socket set and replace with new parts.
Reassemble and ensure all bolts are torqued to manufacturer specifications.
