Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the negative battery cable to prevent electrical shorts.

2. Inspect and Replace Power Steering Components

Inspect Power Steering Fluid:
- Check the fluid level and top off if necessary using the manufacturer's recommended fluid.
- If dark or contaminated, proceed to replace the fluid.
Replace Power Steering Pump (if necessary):
- Remove the serpentine belt using a socket set.
- Disconnect the power steering lines and remove the pump mounting bolts.
- Install the new pump, torque bolts to manufacturer specifications, and reconnect lines.

3. Inspect and Service CV Joints

Visual Inspection:
- Lift the vehicle and remove the front wheels.
- Inspect the CV boots for cracks or leaks; replace if damaged.
Replace CV Joint (if necessary):
- Remove the axle nut and disconnect the lower control arm to free the CV joint.
- Replace the CV joint, ensuring proper alignment and securing with appropriate torque.

4. Wheel Bearing Inspection and Replacement

Check Wheel Bearings:
- Spin the wheel by hand and listen for noise or roughness.
Replace Wheel Bearing (if necessary):
- Remove the brake caliper and rotor.
- Extract the wheel bearing using a bearing puller.
- Install the new bearing, ensuring proper fit and lubrication.

5. Suspension Component Inspection

Examine Control Arms and Bushings:
- Inspect for cracks or excessive play.
Replace Components (if necessary):
- Unbolt the control arm from the chassis and remove it.
- Install new bushings and control arm, tightening bolts to specified torque.
