Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and the keys are removed from the ignition for safety.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure of each tire.
Inflate or deflate the tires to match the manufacturer's specifications, typically found on the driver's side door jamb.
Recheck tire pressure after adjustments.

3. Wheel Alignment

Using a wheel alignment tool, check the alignment settings for camber, caster, and toe angles.
If misaligned, adjust the alignment bolts accordingly to bring the settings within the manufacturer’s specified ranges.
Tighten all bolts to the specified torque values.

4. Suspension Inspection and Repair

Lift the vehicle using a jack and secure it with jack stands.
Inspect all suspension components for wear or damage. Replace any worn or damaged parts, including control arms, tie rods, and bushings.
Lubricate any greasable parts as necessary.

5. Steering System Check

Inspect the steering linkage and rack for any signs of wear or play.
Replace any worn steering components, ensuring they are torqued to the manufacturer’s specifications.

6. Test Drive

Lower the vehicle and remove jack stands.
Conduct a test drive on the highway to ensure the wandering issue is resolved.
