Solution

1. Preparation

Gather tools and safety equipment.
Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, and a fluid catch pan.
Safety Warnings: Ensure the vehicle is on a level surface and securely supported on jack stands before beginning any work.

2. Check and Top Off Power Steering Fluid

Locate the power steering reservoir under the hood.
Remove the cap and check the fluid level; add fluid if low.
Inspect the fluid for contamination (milky appearance) and change if necessary.

3. Inspect and Replace Worn Components

a. Steering Components

Remove the wheel to access the steering linkage.
Use a socket set to disconnect the tie rod ends and inspect for wear.
If worn, replace the tie rods and reconnect, torquing to manufacturer specifications.

b. CV Joints and Axles

Inspect the CV boots for tears or leaks.
If the CV joints are damaged, remove the axle assembly using a socket set.
Replace the axle with a new one, ensuring proper installation and torque specifications.

4. Check and Replace Wheel Bearings

Remove the wheel and brake assembly to access the hub.
Use a pry bar to check for play in the wheel bearings.
If they are worn, remove the hub assembly and replace the bearings.
Reassemble and torque to the manufacturer's specifications.
