Solution

1. Preparation

Gather tools and parts: socket set, jack and jack stands, torque wrench, OBD-II scanner, wheel chocks.
Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Check Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and wipe it clean.
2. Reinsert the dipstick and remove it again to check the fluid level.
3. Inspect the fluid color; it should be red or pink and should not have a burnt smell.
4. If fluid is low or dirty, drain and replace with Toyota WS transmission fluid.
Tools Required: Transmission fluid, funnel, rags.

3. Inspect Wheel Bearings

Sub-steps:
1. Lift the front or rear of the vehicle using a jack and secure with jack stands.
2. Rotate each wheel by hand and listen for any abnormal sounds.
3. Grab the wheel at 12 and 6 o'clock positions and check for excessive play.
4. If play is present, remove the wheel and inspect the bearing for wear or damage.
Tools Required: Socket set, torque wrench.

4. Examine Drive Belts and Pulleys

Sub-steps:
1. Open the hood and inspect drive belts for signs of wear, cracks, or fraying.
2. Check that the belts are properly tensioned and aligned on pulleys.
3. If wear is evident, remove the old belt and replace it with a new one, following the routing diagram.
Tools Required: Socket set, belt tensioner tool.

5. Investigate Power Steering Pump

Sub-steps:
1. Check the power steering fluid level in the reservoir and top off if necessary.
2. Start the engine and turn the steering wheel from lock to lock while listening for noise.
3. If noise persists, consider replacing the power steering pump.
Tools Required: Power steering fluid, socket set.
