Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is on a level surface and securely lifted using jack stands.
Disconnect the battery to prevent electrical shorts during repairs.

2. Inspect and Replace Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check fluid level; if low, top off with the manufacturer-recommended fluid.
If the fluid is dark or contaminated, drain and replace the fluid:
1. Disconnect the power steering return line and drain old fluid into a container.
2. Reconnect the return line.
3. Fill the reservoir with new power steering fluid.

3. Replace Worn Suspension Components

For any identified worn suspension components:
1. Remove the wheel to access suspension parts.
2. Use a socket set to remove the bolts securing the damaged components (e.g., tie rods, control arms).
3. Replace with new parts, ensuring they are properly aligned.
4. Torque bolts to manufacturer's specifications.

4. Inspect and Replace Wheel Bearings (if necessary)

If wheel bearings are found to be faulty:
1. Remove the wheel and brake caliper.
2. Remove the hub assembly using a puller if necessary.
3. Replace the bearings and reassemble, ensuring proper torque specifications are followed.

5. Check and Replace CV Joints

If CV joints are damaged:
1. Lift the vehicle and remove the front wheels.
2. Disconnect the axle from the transmission and the wheel hub.
3. Replace the CV joint or axle assembly as needed.
4. Reinstall and torque all fasteners to specifications.
