Pic. 4.36. Exclusion of tightness when tightening silent blocks when installing the suspension arm: 1 - plug of the ball joint
Attention! When installing to eliminate tension when tightening silent blocks, set the suspension arm so that the center distance X1 = 24 mm between the lower part of the ball joint of the arm and the lower part of the subframe at the level of the hole in the center of the arm W1 (pic. 4.36).
Place a hydraulic jack under the subframe in the area of the middle hole of the suspension arm W1 and raise it until it comes into contact with the subframe.
Lower the hydraulic jack to dimension X1 = 24 mm.
Position the ball joint plug on the hydraulic jack without changing the position of the control arm.
In this position, tighten the bolts of the front and rear mountings of the suspension arm to the subframe to the required torque of 105 Nm.
Remove the hydraulic jack.
Insert the ball joint of the suspension arm into the steering knuckle.
Install and tighten to the required torque:
- subframe connecting rod lower mounting nut (62 Nm);
- subframe tie rod upper mounting bolt (210 Nm);
