Solution

1. Preparation

Gather tools and parts required.
Park the vehicle on a level surface and ensure the engine is off.
Lift the front of the vehicle using a jack and secure it with jack stands.

2. Inspect and Replace Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; top off with the recommended fluid if low.
If the fluid is dark or contaminated, drain and replace it with new fluid.

3. Replace Worn Steering Components

Steering Tie Rods:
- Remove the cotter pin and nut from the tie rod end.
- Use a tie rod puller to detach it from the steering knuckle.
- Install the new tie rod end and torque to the manufacturer's specification.
Ball Joints:
- Remove the wheel and brake caliper.
- Unbolt the ball joint from the control arm.
- Install the new ball joint and torque to specification.

4. Inspect and Replace CV Joints (if necessary)

Remove the wheel and brake assembly.
Detach the axle from the hub assembly.
Inspect the CV joint boot for tears; if damaged, replace the CV joint.
Reassemble by reinstalling the axle and torquing all fasteners to specification.

5. Inspect and Replace Wheel Bearings (if necessary)

Remove the wheel and brake assembly.
Use a bearing puller to remove the old wheel bearing.
Install the new wheel bearing and ensure proper seating.
Reassemble all components and torque to specifications.
