Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, torque wrench, socket set, multimeter (if needed for electrical components).
Ensure the vehicle is parked on a level surface and securely lifted before starting any repair.
Disconnect the battery if working on electrical components.

2. Brake Inspection and Replacement

Sub-steps:
1. Remove the wheel using a lug wrench.
2. Inspect brake pads and rotors for wear. Pads should have at least 3mm of material; rotors should be smooth.
3. If worn, replace brake pads and/or rotors:
  - Remove caliper bolts and slide the caliper off the rotor.
  - Replace pads and, if necessary, the rotor.
  - Reinstall the caliper and torque bolts to manufacturer specifications.
  - Reinstall the wheel and torque lug nuts to the specified value.

3. Transmission Fluid Check and Replacement

Sub-steps:
1. Locate the transmission dipstick and pull it out to check the fluid level.
2. If low or discolored, drain the old fluid using the drain plug.
3. Replace with the recommended transmission fluid type.
4. Recheck the fluid level after running the engine for a few minutes.

4. Wheel Bearing Inspection and Replacement

Sub-steps:
1. Lift the vehicle and remove the wheel.
2. Grasp the wheel at the 12 and 6 o'clock positions and shake it. Excessive movement indicates a bad bearing.
3. Remove the hub assembly if replacement is necessary.
4. Install a new wheel bearing by following the manufacturer's specifications for pressing it into the hub.
5. Reassemble the wheel and torque all components to specification.
