PRECAUTIONS AND PREPARATION
Precautions
q When installing rubber parts, final tightening must be car-
ried 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.
q Use flare nut wrench when removing and installing brake
tubes.
q After installing removed suspension parts, check wheel
alignment and adjust if necessary.
q Always torque brake lines when installing.
