q q SBR686C q
When installing rubber parts, final tightening must be carried out under unladen condition* with tires on ground. *: Fuel, radiator coolant and engine oil full. Spare tire, jack, hand tools and mats in designated positions. After installing suspension parts, check wheel alignment and adjust if necessary. Use flare nut wrench when removing or installing brake tubes. Always torque brake lines when installing.
