Tools Required: Jack and jack stands, torque wrench, tie rod end puller.
Lift the vehicle and secure it on jack stands.
Remove the front wheels to access the steering components.
Inspect tie rod ends for play and wear; replace if necessary.
Inspect the steering rack for any leaks or damage; replace if necessary.
Reassemble the components and ensure all fasteners are torqued to specifications.

5. Wheel Bearing Inspection

Tools Required: Socket set, torque wrench, wheel bearing grease.
Spin the wheel by hand while checking for noise or roughness.
If the wheel bearing is faulty, remove the hub assembly to access the bearing.
