Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Power Steering Fluid

Check the power steering fluid reservoir for proper level and condition.
If low or contaminated, drain the old fluid using a turkey baster or siphon.
Refill with manufacturer-recommended power steering fluid.

3. Replace Worn Steering Components

Tie Rods:
- Raise the vehicle using a jack and secure it with jack stands.
- Remove the wheel to access tie rods.
- Use a wrench to disconnect the tie rod end from the steering knuckle.
- Install the new tie rod end and torque to manufacturer specifications (typically 35-45 ft-lbs).
Ball Joints:
- Remove the wheel and unfasten the ball joint nut.
- Use a ball joint separator tool to detach it from the control arm.
- Install the new ball joint and torque to manufacturer specifications.

4. Inspect and Replace CV Joints

Lift the vehicle and remove the wheel.
Inspect the CV joint boot for tears. If damaged, replace the entire axle assembly.
If boots are intact, ensure the joint is lubricated and free of debris.

5. Replace Wheel Bearings (if necessary)

Remove the wheel and brake caliper.
Use a bearing puller to remove the old bearing from the hub.
Press in the new wheel bearing and reassemble the components.
Torque all bolts to manufacturer specifications.
