1. Check all fasteners for proper torque. Check to ensure there is adequate clearance between all rotating, mobile,
fixed and heated members. Check steering for interference and proper working order. Test brake system.
2. Perform steering sweep. The distance between the tire sidewall and the brake hose must be checked closely. Cycle
the steering from full turn to full turn to check for clearance. Failure to perform inspections may result in component
failure.
3. Re torque all fasteners after 500 miles. Visually inspect components and re torque fasteners during routine vehicle
service.
