Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and the tires are cool.

2. Tire Pressure Adjustment

Tools Required: Tire pressure gauge, air compressor
Check and adjust the tire pressure on all four tires to match the manufacturer's specifications found in the owner's manual or door jamb sticker.

3. Wheel Alignment

Tools Required: Alignment machine (or alignment tools), jack, jack stands
Lift the vehicle using a jack and secure it with jack stands.
Mount the alignment machine according to the manufacturer instructions.
Adjust the camber, caster, and toe settings to match the specifications for the 2013-2019 Toyota Corolla E170.

4. Suspension Inspection and Repair

Tools Required: Socket set, torque wrench, visual inspection tools
Visually inspect all suspension components for signs of wear or damage.
Replace any worn components (e.g., bushings, shocks, struts) as needed.
Use a torque wrench to tighten all bolts to the manufacturer’s specifications.

5. Tire Rotation and Replacement (if necessary)

Tools Required: Jack, jack stands, tire iron
Rotate the tires to ensure even wear across all tires, following the recommended rotation pattern in the owner’s manual.
If any tires are excessively worn, replace them with new tires that meet manufacturer standards.
