Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fluid dipstick, flashlight.
Ensure the vehicle is parked on a level surface and the engine is off before starting any inspection.

2. Inspect and Replace Serpentine Belt

Open the hood and locate the serpentine belt.
Use a socket set to release tension from the belt tensioner and remove the serpentine belt.
Inspect the belt for cracks, fraying, or glazing.
If damaged, replace with a new serpentine belt according to manufacturer specifications (length: typically around 78 inches for E170).
Reinstall the new serpentine belt and ensure it is properly routed.

3. Check and Refill Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level. If low, add power steering fluid as per specification (typically ATF or specific power steering fluid).
Start the engine and turn the steering wheel from lock to lock to bleed air out of the system.
Recheck fluid level and top off if necessary.

4. Inspect and Replace Wheel Bearings (if necessary)

Lift the vehicle and secure it on jack stands.
Remove the wheel and inspect the wheel bearing for play or noise by rotating the hub.
If noise or play is present, remove the hub assembly and replace the wheel bearing using a bearing puller.
Reassemble the wheel hub, torque the bolts to manufacturer specifications, and reinstall the wheel.

5. Transmission Fluid Check

Start the engine and set the transmission in park or neutral.
Remove the transmission dipstick to check the fluid level and condition.
If low, add the appropriate transmission fluid (typically Toyota Type T-IV).
If the fluid smells burnt or is discolored, consider a fluid change and filter replacement.
