what causes my Toyota Corolla E170 (2013-2019) to wander while driving?

Solution

1. Preparation

• Gather tools and materials: alignment tool, tire pressure gauge, jack and jack stands, wrench set, and torque wrench.
• Park the vehicle on a flat, level surface and engage the parking brake.

2. Tire Inspection

• Sub-steps:
  1. Check tire pressure using the tire pressure gauge and inflate to recommended PSI if necessary.
  2. Visually inspect each tire for uneven wear patterns; note any bald spots or irregularities.
• Tools Required: Tire pressure gauge, air compressor (if needed)

3. Alignment Correction

• Sub-steps:
  1. If misalignment is detected, use an alignment tool to adjust the camber, caster, and toe angles to the manufacturer's specifications.
  2. Tighten all adjustment bolts to the specified torque values (usually around 50-70 ft-lbs).
• Tools Required: Alignment tool, torque wrench

4. Suspension Component Inspection and Replacement

• Sub-steps:
  1. Raise the vehicle using a jack and secure it with jack stands.
  2. Inspect tie rods, ball joints, and bushings for wear; replace any components found to be worn or damaged.
  3. Reassemble any removed components and ensure all bolts are torqued to manufacturer specifications.
