Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, dial gauge, torque wrench, brake cleaner
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Remove Wheel

Loosen the lug nuts with a lug wrench.
Raise the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper by loosening the caliper bolts with a socket set.
- Inspect brake pads for thickness; replace if worn below specifications (usually 3mm).
Brake Rotors:
- Remove the rotor by taking off the retaining screws if applicable.
- Use a dial gauge to check for warping; replace if runout exceeds manufacturer specifications (typically 0.002 inches).

4. Inspect Suspension and Wheel Bearings

Check control arms, bushings, and tie rods for wear or damage.
Grasp the wheel at the top and bottom; if there is excessive play, inspect the wheel bearings and replace if necessary.

5. Reassemble and Reinstall

If any components are replaced, install new parts in reverse order. Ensure the rotor and brake pads are correctly aligned.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle and Torque Lug Nuts

Lower the vehicle back to the ground.
Use a torque wrench to tighten the lug nuts to the manufacturer’s specifications (usually around 76 ft-lb for the Corolla).
