Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and turn off the engine.
Gather necessary tools and parts.
Tools Required: Jack, jack stands, socket set, torque wrench, OBD-II scanner.

2. Inspect Steering Components

Raise the front of the vehicle using a jack and secure it on jack stands.
Visually inspect the steering linkage, including the rack and pinion assembly, for any signs of damage or excessive play.
Check the tie rod ends for wear by moving them back and forth; any movement should be minimal.

3. Check Fluid Levels

Locate the power steering reservoir and remove the cap.
Inspect the fluid level; it should be between the "MIN" and "MAX" marks.
If low, add the appropriate power steering fluid as specified in the owner's manual.

4. Tighten Loose Components

If any bolts or nuts in the steering assembly or suspension are loose, tighten them to the manufacturer’s specifications using a torque wrench.
Consult the service manual for specific torque values for each component.

5. Replace Worn Components

If any components such as tie rod ends or ball joints are found to be worn or damaged, replace them.
Remove the affected part using a socket set and install the new component, ensuring all bolts are torqued to specifications.
