Solution

1. Preparation

Gather all required 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

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check the fluid level. If low, top it off with the manufacturer-recommended fluid type.
3. If the fluid appears dirty or contaminated, drain the old fluid by loosening the return hose at the pump.
4. Refill with new power steering fluid and recheck the level.

3. Check and Replace Steering Components

Sub-steps:
1. Raise the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels to gain access to the steering and suspension components.
3. Inspect the tie rod ends and steering rack for any signs of wear or damage.
4. If any components are found damaged, replace them with OEM or quality aftermarket parts.
5. Reinstall the wheels and lower the vehicle back to the ground.

4. Inspect Wheel Bearings

Sub-steps:
1. With the front wheels still off, grasp each wheel at the top and bottom and shake to check for play.
2. If play is detected, remove the wheel hub assembly to access the bearings.
3. Inspect the bearings for wear; if damaged, replace them.
4. Reassemble the hub and wheel, ensuring all bolts are torqued to manufacturer specifications.

5. Test Drive

After all repairs, take the vehicle for a test drive to ensure that the grinding noise is no longer present and that steering feels normal.
