While securely raising the vehicle, take off the wheel and make a dot to remember where the strut connected to the steering knuckle. Get the brake tube off the strut, then secure the control arm. Tilt the car up and put supports in place. Disconnect bolts that join the steering knuckle to the strut, prop up the strut, and take out the three attachment nuts above the strut to the hood, and pull off the strut assembly. Set the new strut assembly onto your vehicle and tighten the body (hood) nuts to 29-40 ft. lbs of torque for 240SX models.
