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 while working on the vehicle.

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, add manufacturer-recommended fluid.
3. If the fluid appears dark or contaminated, proceed to flush the system.
4. Use a turkey baster or fluid pump to remove old fluid from the reservoir.
5. Refill with fresh power steering fluid and check for leaks.

3. Check and Replace Steering Rack

Sub-steps:
1. Remove the front wheels to access the steering components.
2. Disconnect the tie rod ends from the steering rack.
3. Remove any mounting bolts securing the steering rack to the subframe.
4. Disconnect the power steering lines from the rack (be prepared for fluid spillage).
5. Replace with a new or refurbished steering rack and reassemble in reverse order.

4. Inspect and Replace Wheel Bearings

Sub-steps:
1. After removing the front wheels, inspect the wheel bearings for any signs of grinding or excessive play.
2. If necessary, remove the brake caliper and rotor to access the bearings.
3. Use a bearing puller to remove the old bearings from the hub.
4. Install new wheel bearings, ensuring proper alignment and lubrication.
5. Reassemble all components, ensuring all fasteners are torqued to the manufacturer's specifications.
