 Remove the T30 Torx screws holding the heat shield in place and remove it from the steering gear.
 Note the position of the servo motor unit within the steering gear housing.
 Following the sequence 1, 2, and 3 shown (Figure 2) loosen the three T40 Torx screws about half a
turn to relieve tension in the servo motor unit.
Figure 2
 Grasp the servo motor unit by hand (no tools) and rotate it a few times back and forth slightly in the
steering gear housing without exerting force on the flange (Figure 3).
Figure 3
 Return the servo motor unit to its starting position.
 Tighten the three T40 Torx screws in sequence 1, 2 and 3 (Figures 2, 4, 5 and 6) with a torque of 10

 Retighten the three T40 Torx screws in sequence 1, 2 and 3 (Figures 2, 4, 5 and 6) with a turning
angle of 65°.
 Verify the final torque of the three T40 Torx screws in sequence 1, 2, and 3 (Figures 2, 4, 5 and 6)
using a torque value of 25 Nm while checking that no more than 10° of additional turn is applied.
Note:
If a torque of 25 Nm is not reached with no more than 10° of additional turn (max. total turn 75°), then the
steering gear must be replaced! Worn or damaged threads are non-repairable.
