Solution

1. Preparation

Gather tools: socket set, torque wrench, jack stands, and a power steering fluid reservoir.
Ensure the vehicle is parked on a level surface with the ignition off.

2. Inspect and Replace Power Steering Fluid

Check Fluid Level: Remove the power steering fluid reservoir cap and check the fluid level. If low, top off with manufacturer-recommended fluid.
Replace Fluid: If the fluid is dark or contaminated, drain the old fluid by disconnecting the return line from the pump and allowing it to drain into a suitable container. Reconnect the line and fill with new fluid. Start the engine and turn the steering wheel from lock to lock to purge air.

3. Replace Faulty Components

Steering Rack: If the steering rack is damaged, disconnect the battery, remove the steering column covers, and detach the steering linkage. Unbolt the steering rack from its mounting points and replace it with a new unit. Reinstall all components in reverse order.
Tie Rods and Ball Joints: Use a ball joint separator to remove any worn tie rods or ball joints. Replace them with new components and torque to manufacturer specifications.

4. Inspect and Replace Wheel Bearings

Wheel Bearing Identification: Jack up the vehicle, remove the wheel, and inspect the bearing for play or noise.
Replace Bearing: If necessary, use a bearing puller to remove the old bearing and install a new one, ensuring proper orientation and lubrication.

5. Reassemble and Test

Reinstall any components that were removed during inspection and ensure all bolts are torqued to specifications.
Lower the vehicle and check for proper operation by turning the steering wheel while stationary and during a test drive.
