Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, torque wrench, fluid container for fluid disposal.
Ensure the vehicle is on a flat surface and securely parked.
Disconnect the battery to prevent electrical issues while working on the vehicle.

2. Inspect and Replace Power Steering Fluid

Remove the power steering reservoir cap.
Check the fluid level; if low, top it off with the recommended fluid type.
If the fluid is dark or contaminated, drain the old fluid from the system and replace with new fluid.

3. Inspect Suspension Components

Raise the front of the vehicle using a jack and secure it with jack stands.
Visually inspect control arms, ball joints, and tie rods for signs of wear or damage.
Replace any worn components using the following sub-steps:
- Ball Joint Replacement:
  1. Remove the wheel and tire assembly.
  2. Unbolt the ball joint from the control arm.
  3. Install the new ball joint and torque to the manufacturer’s specifications.
- Tie Rod Replacement:
  1. Remove the tie rod end from the steering knuckle.
  2. Replace with a new tie rod and torque to specifications.

4. Inspect and Replace Wheel Bearings

Remove the wheel assembly to access the hub.
Check for play in the wheel bearings by moving the hub side to side.
If worn, replace the bearings:
1. Remove the hub assembly and press out the old bearings.
2. Install new bearings and reassemble the hub.

5. Reassemble and Test

Reinstall the wheel assembly and lower the vehicle.
Reconnect the battery.
Test drive the vehicle to ensure the grinding noise is resolved.
