Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat 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 reservoir and check the fluid level.
2. If the fluid is low or dirty, drain the existing fluid using a siphon pump.
3. Refill with the manufacturer's recommended power steering fluid (typically Toyota ATF).
4. Start the engine and turn the steering wheel from lock to lock to purge air from the system.
5. Recheck fluid level and top off as necessary.

3. Inspect and Replace Power Steering Pump (if needed)

Tools Required: Socket set, torque wrench, power steering pump puller (if applicable).
Sub-steps:
1. Remove any accessories or brackets obstructing access to the power steering pump.
2. Disconnect the power steering hoses and cap openings to prevent contamination.
3. Unbolt the power steering pump from its mounting location.
4. Install the new power steering pump and torque bolts to manufacturer specifications.
5. Reattach hoses and refill power steering fluid.

4. Check and Adjust Wheel Alignment

Sub-steps:
1. Use a wheel alignment tool to measure alignment angles.
2. If misaligned, adjust the tie rods to bring the front wheels into proper alignment specifications.
3. Test drive the vehicle to ensure proper steering response post-adjustment.
