Move vehicle backwards and forwards a short distance to allow suspension components to adjust. Turn the front wheels completely left then right and verify adequate tire, wheel, brake line, and ABS wire clearance. Test and inspect steering, brake and suspension components for tightness and proper operation. In-spect brakes hoses and ABS lines for adequate slack at full extension. Failure to perform the post in-spection checks may result in vehicle component damage and/or personal injury or death to driver and/ or passengers. Test drive vehicle and re-check the torque of all fasteners and re-torque wheels on ve-hicle. Re-adjust headlamps.
Vehicle Handling Warning: Vehicles with larger tires and wheels will handle differently than stock vehicles. Take time to familiarize yourself with the handling of your vehicle.
Wheel Alignment/Headlamp Adjustment: It is necessary to have a proper and professional wheel alignment performed by a certified alignment technician. Align the vehicle to factory specifications. It is recommended that your vehicle alignment be checked after any off-road driving. In addition to your vehicle alignment, for your safety and others, it is necessary to check and adjust your vehicle headlamps for proper aim and alignment
