⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under the vehicle.
•Wear safety glasses when performing any repairs to protect eyes from debris.

Symptoms

•Vehicle drifts to one side while driving straight
•Uneven tire wear
•Steering wheel off-center when driving straight
•Increased steering effort required to maintain a straight line
•Vibration in the steering wheel at higher speeds

Diagnostic Steps

1
Inspect tire pressure on all four tires and ensure they are inflated to manufacturer specifications.
2
Check for uneven tire wear patterns that may indicate alignment issues.
3
Perform a visual inspection of suspension components for damage or wear (e.g., bushings, shocks, struts).
4
Use a wheel alignment tool to measure alignment angles (camber, caster, toe).
5
Check for any error codes related to the Vehicle Dynamics Controller using the OBD-II scanner.

Solution

1. Preparation

Gather tools: alignment tools, torque wrench, jack and jack stands, tire pressure gauge.
Ensure the vehicle is on a flat and level surface.

2. Inspect and Adjust Tire Pressure

Sub-steps:
- Use a tire pressure gauge to check each tire's pressure.
- Inflate or deflate tires to match the manufacturer's recommended pressure.

3. Perform Wheel Alignment

Sub-steps:
- Raise the vehicle using a jack and secure it on jack stands.
- Remove any wheel covers or hubcaps to access the wheel lug nuts.
- Loosen the lug nuts and remove the front wheels.
- Attach the alignment tool according to the manufacturer’s instructions.
- Adjust the alignment settings (camber, caster, toe) to fall within manufacturer specifications.
- Reinstall the wheels and tighten lug nuts to the specified torque.

4. Inspect and Replace Suspension Components (if necessary)

Sub-steps:
- If any suspension components are damaged or worn, remove the affected part(s) following manufacturer guidelines.
- Install new components, ensuring they are properly torqued to specifications.
- Recheck alignment after replacement.

5. Final Checks

Lower the vehicle and remove jack stands.
Test drive the vehicle to ensure the drifting issue is resolved.
