Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and parked safely.
Tools Required: Jack, jack stands, tire pressure gauge, alignment tool, tread depth gauge, torque wrench.

2. Adjust Tire Pressure

Check each tire’s pressure against the manufacturer’s specifications (usually found on the driver’s side door jamb).
Inflate or deflate tires as needed.

3. Rotate Tires

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel lug nuts using a socket set.
Rotate the tires as per the manufacturer’s recommended pattern (e.g., front to back, side to side).
Reinstall the lug nuts and torque them to specifications (usually around 76 ft-lbs for Corolla).

4. Perform Wheel Alignment

Use an alignment tool to measure the alignment angles.
Adjust the toe, camber, and caster as necessary according to the manufacturer’s specifications.
Lock down any adjustment bolts and verify that the angles are within acceptable limits.

5. Inspect and Replace Suspension Components (if necessary)

Visually inspect shocks, struts, and control arms for any signs of wear or damage.
Replace any worn components using appropriate tools and ensure everything is torqued to specifications.
