Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Power Steering Fluid

Locate the power steering reservoir.
Check the fluid level; if low, fill it with the manufacturer-recommended fluid (e.g., ATF or specific power steering fluid).
If fluid is dirty or contaminated, drain the old fluid using a siphon or turkey baster.
Refill with new power steering fluid and check for leaks after use.

3. Inspect Steering Components

Examine the steering rack for any visible leaks or damage.
Check tie rod ends and ball joints for wear; replace any parts that are worn or damaged.
Use a torque wrench to ensure all connections are tightened to manufacturer specifications.

4. Inspect Suspension Components

Check struts for leaks or damage; if needed, replace struts.
Inspect bushings for wear; replace any that are cracked or deteriorated.
Ensure all suspension bolts are tightened to specifications.

5. Check and Rotate Tires

Inspect tires for uneven wear patterns and check for proper inflation.
Rotate tires if uneven wear is detected.
Align the wheels if necessary.
