Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, OBD-II scanner, brake cleaner, socket set.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery if working on electrical components.

2. Tire Inspection and Adjustment

Sub-steps:
1. Use the lug wrench to loosen the lug nuts on all tires.
2. Jack up the vehicle and place it securely on jack stands.
3. Remove the wheels and inspect for uneven wear or damage.
4. Check tire pressure with a gauge and inflate to the manufacturer's recommended PSI.
5. Reinstall wheels, hand-tighten lug nuts, lower the vehicle, and torque lug nuts to the specified value (typically 76 ft-lbs for Corolla).

3. Brake System Inspection

Sub-steps:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads for wear; replace if less than 3mm thick.
3. Check caliper movement; ensure calipers slide freely on their pins. Clean and lubricate if necessary.
4. If dragging is suspected, check the brake lines for kinks or blockages.
5. Reassemble the brake components and wheel.

4. Transmission Fluid Check

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Wipe it clean, then reinsert and pull it out again to check the fluid level.
3. If low, add the recommended ATF (Toyota Type T-IV).
4. Check fluid condition; if burnt or dirty, consider a transmission fluid change.

5. Wheel Bearing Inspection

Sub-steps:
1. Spin each wheel by hand to listen for grinding noises.
2. Inspect the wheel hub for play by pushing and pulling on the wheel.
3. If excessive play is felt, replace the wheel bearings as necessary.

6. Engine Mount Assessment

Sub-steps:
1. Inspect the engine mounts visually for cracks or separation.
2. Start the engine and observe for excessive movement when revving.
3. Replace any damaged mounts to restore proper alignment.
