Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the 12V battery for safety, if necessary.

2. Tire Inspection

Remove any wheel covers or hubcaps.
Inspect tire pressures and adjust to the recommended PSI as per the owner's manual.
Examine all four tires for uneven wear, bulges, or damage.

3. Wheel Alignment Adjustment

Tools Required: Wheel alignment tool, torque wrench, socket set.
Set up the wheel alignment tool according to the manufacturer’s instructions.
Adjust the alignment settings to the manufacturer's specifications (camber, caster, and toe).
- Camber: Typically between -0.5° to +0.5°.
- Toe: Often set to 0.05° to 0.15° in/out depending on specifications.
Tighten all bolts to the specified torque using a torque wrench.

4. Suspension Inspection and Repair

Inspect the suspension components (control arms, bushings, struts, and shocks).
Replace any worn or damaged components as needed.
- Parts Required: Replacement bushings, struts, or control arms.

5. Reassemble and Test

Reinstall any wheel covers or hubcaps.
Reconnect the 12V battery if it was disconnected.
Test drive the vehicle to ensure the drift has been corrected.
