Remove the power steering fluid reservoir cap.
Using a turkey baster or similar tool, extract old fluid from the reservoir.
Refill the reservoir with the manufacturer-recommended power steering fluid.
Start the engine and turn the steering wheel from lock to lock to bleed air from the system.
Inspect for leaks after refilling.

3. Replace Damaged Tie Rod Ends (if applicable)

Remove the cotter pin and nut securing the tie rod end to the steering knuckle.
Use a tie rod end puller to separate the tie rod from the steering knuckle.
Install the new tie rod end and torque to manufacturer specifications.
Reinstall the cotter pin and nut.

4. Inspect and Replace CV Joints (if applicable)

Lift the vehicle and remove the wheel.
Inspect the CV joint boot for tears or leaks.
If damaged, remove the axle nut and separate the axle from the hub.
Replace the CV joint and reassemble using new grease and a new boot if necessary.
Torque the axle nut to the specified value.

5. Inspect and Replace Wheel Bearings (if applicable)

Remove the wheel and brake assembly to access the hub.
Use a bearing puller to remove the old wheel bearing.
Install the new bearing, ensuring it is seated correctly.
Reassemble the brake assembly and wheel, torquing all hardware to specification.
