Solution

1. Preparation

Tools Required: Socket set, screwdrivers, fluid catch pan, OBD-II scanner, torque wrench.
Ensure the vehicle is on a level surface and the engine is off. Disconnect the battery if necessary.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check fluid level and condition (should be clear, not dark or contaminated).
3. If the fluid is low, top it off with the manufacturer-recommended power steering fluid.
4. If the fluid is contaminated, drain the system using a fluid catch pan and replace with new fluid.

3. Check and Replace Power Steering Pump

Sub-steps:
1. Locate the power steering pump (usually near the front of the engine).
2. Disconnect the power steering hoses and remove the pump using a socket set.
3. Inspect the pump for wear or damage.
4. Install the new power steering pump, ensuring all connections are tight.
5. Refill the power steering fluid reservoir after installation.

4. Inspect and Replace Steering Rack

Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Remove the front wheels for easier access to the steering rack.
3. Disconnect the tie rods from the steering rack.
4. Remove any bolts securing the rack to the chassis and disconnect the steering shaft.
5. Remove the old steering rack and install the new one, following the reverse order of disassembly.
6. Align the tie rods and tighten all fasteners to the manufacturer's torque specifications.

5. Inspect Suspension Components

Sub-steps:
1. Check ball joints and tie rods for any signs of wear or play.
2. Replace any worn components with new parts, ensuring proper alignment after installation.
3. Reassemble any removed components and wheels.
