    NOTE:

    Before tightening the bolts, press the knuckle toward the vehicle to achieve the most negative camber. If this is not done, it is possible to have positive camber which will negatively impact vehicle handling.

  4. Position the lower end of the strut assembly in line with the upper end of the knuckle (3), aligning the mounting holes. Install the two mounting bolts (4) from the front side of the vehicle.
  5. Install the nuts (2) on the two bolts (4). Press the knuckle inward towards the vehicle, and tighten the nuts to 75 N.m (55 ft. lbs.).
