  1. Tighten the bolts first on the bearing tab side (1) of the cap.

    Torque for bolts ... 260 ± 14 N·m (190 ± 10 lb ft)

  1. Tighten the bolts on the opposite side (2) .

    Torque for bolts ... 260 ± 14 N·m (190 ± 10 lb ft)

  1. Put a mark on each bolt and each cap.
  1. Tighten the bolts on the opposite side (3) from the mark to angle (A) .

    Angle (A) ... 120 ± 5 degrees (2 flats)
