- - front suspension arms;
- - torque rod of the lower support of the power unit.
Installation
Attention. Reuse of the front suspension subframe mounting bolts is not allowed. The bolts must be replaced.
Attention. Reuse of the ball joint mounting nut to the steering knuckle is not allowed. The nut must be replaced.
If removed, install on the subframe:
- - front suspension arms;
- - anti-roll bar;
- - torque rod of the lower support of the power unit.
Install the subframe on the car and screw in new mounting bolts without tightening. The operation should be performed by two performers (18 mm socket, ratchet wrench, transmission rack).
Finally tighten the subframe mounting bolts in the sequence shown in Figure 2. The bolt tightening torque is 105 Nm (10.5 kgf.m) (18 mm socket, torque wrench).
Install the steering gear on the front suspension subframe and secure with bolts.
The bolt tightening torque is 105 Nm (10.5 kgf.m) (18 mm socket, ratchet wrench, torque wrench).
