Solution

1. Preparation

Tools Required: OBD-II scanner, jack and jack stands, socket set, torque wrench, flashlight.
Safety Warnings: Disconnect the battery before working on electrical components.

2. Inspect and Replace Power Steering Fluid

Locate the power steering reservoir.
Check the fluid level; if low, top off with manufacturer-recommended fluid.
If fluid is discolored or contaminated, drain the old fluid using a siphon.
Refill with new power steering fluid to the appropriate level.

3. Inspect Steering Linkage and Suspension

Raise the front of the vehicle using a jack and secure with jack stands.
Remove the front wheels using a socket set.
Visually inspect all steering components (tie rods, ball joints) and suspension (struts, bushings) for signs of wear or damage.
If any components are found defective, replace them with OEM parts following the manufacturer's specifications.

4. Check and Adjust Wheel Alignment

After inspecting the suspension, check for proper wheel alignment.
If misaligned, use an alignment tool to adjust the angles to manufacturer specifications.
Reinstall the wheels and torque the lug nuts to the manufacturer's specifications.
