Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace Power Steering Fluid

Tools Required: Funnel, clean rag
Drain the existing power steering fluid using a syringe or pump.
Refill 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.

3. Inspect and Replace Worn Steering Components

Tools Required: Socket set, torque wrench, pry bar
Remove the front wheels using a jack and jack stands.
Inspect tie rods and ball joints for movement and wear.
If worn, replace the affected components:
- Remove the cotter pin and castle nut from the tie rod or ball joint.
- Use a pickle fork to separate the joint from the steering knuckle.
- Install the new part and torque the castle nut to the manufacturer's specifications.

4. Inspect and Replace CV Joints

Tools Required: Socket set, CV joint snap ring pliers
Inspect the CV joints for cracks or tears in the boots.
If damaged, remove the axle from the vehicle:
- Remove the axle nut and any retaining clips.
- Pull the axle out of the transmission and steering knuckle.
Replace the CV joint or entire axle assembly as necessary, ensuring to use new grease and follow torque specs during reinstallation.

5. Check and Replace Wheel Bearings

Tools Required: Bearing puller, socket set, torque wrench
Remove the hub assembly from the vehicle.
Inspect the wheel bearings for smoothness and play.
If they are worn or noisy, replace them:
- Remove the old bearings and clean the hub.
- Install the new bearings and pack them with grease.
- Reassemble the hub, ensuring proper torque on all fasteners.
