Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, socket set, torque wrench, power steering fluid
Ensure the vehicle is on a flat surface and securely raised with jack stands. Disconnect the battery for safety.

2. Inspect Power Steering System

Sub-steps:
1. Locate the power steering reservoir and check the fluid level.
2. If low, top off with the manufacturer-recommended power steering fluid.
3. Inspect hoses and connections for leaks or cracks. Tighten any loose connections or replace damaged hoses.

3. Check Steering Components

Sub-steps:
1. Visually inspect the steering rack and tie rods for any visible damage or play.
2. If damaged, remove and replace the affected components. Use a torque wrench to tighten bolts to the manufacturer's specifications.

4. Inspect Wheel Bearings

Sub-steps:
1. Lift the vehicle and remove the wheel using a socket set.
2. Grab the wheel at the top and bottom and attempt to rock it back and forth.
3. If there is excessive play, the wheel bearings need to be replaced. Remove the hub assembly to access the bearings and replace them.

5. Examine CV Joints and Axles

Sub-steps:
1. Inspect the CV boots for tears or leaks. Replace any damaged boots.
2. Check the CV joints for play. If worn, remove the axle and replace the CV joint or the entire axle assembly.
