Installation
Figure 5-3 - Diagram of the location of the front suspension arm relative to the subframe when tightening the rubber-metal hinges: 1 - ball joint of the front suspension arm; 2 - front suspension subframe; X1 - the size for installing the lever is 24 mm
Attention. To tighten the rubber-to-metal joints of the front suspension arm when dry, install the arm as shown in Figure 5-3. The dimension in the vertical direction from the lower point of the ball joint housing to the lower part of the subframe in the area of the hole in the center of the lever attachment to the subframe must be X1 = 24 mm.

The procedure for tightening the rubber-metal hinges of the front suspension arm:
- install a hydraulic jack under the subframe in the area of the hole "A", figure 5-4, in the center of the front suspension arm mounting;
- adjust the height of the jack rod extension so that the distance between the heel of the jack and the lower part of the subframe corresponds to the dimension X1 = 24 mm, Figure 5-3;
- move the jack under the ball joint to the point "B", Figure 5-4, and position the lever so that the ball joint body rests on the heel of the jack rod;
- finally tighten the nuts of the front suspension arm bolts to the subframe. Nut tightening torque 105 Nm (10.5 kgf·m) (ring wrench 18, interchangeable head 18 long, torque wrench).
Install the anti-roll bar strut elements on the lever: washer, upper rubber-metal hinge, install two rubber bushings between the lever and the stabilizer, install the mounting bolt, lower rubber-metal hinge, pull off the package of strut elements with a clamp and tighten the nut. Nut tightening torque 14 Nm (1.4 kgf·m) (Clamp Sus. 1413 and Sus. 1734, Torx T40 angle wrench, interchangeable head 13, ratchet wrench, torque wrench).
Reinstall the stretching of the subframe and tighten the bolt for fastening the link to the side member and the nut for fastening the link to the front suspension arm. Bolt tightening torques 62 Nm (6.2 kgf·m), nuts 62 Nm (6.2 kgf·m) (interchangeable head 13, 18, ratchet wrench, torque wrench).
Install the front fender side mudguard.
Install the front wheel.
Check and adjust if necessary front wheel alignment angles.
