Front Subframe Torque
After removing the subframe mounting bolts, the front suspension subframe middle mounting rubber mounting bolts, the front suspension subframe rear bracket mounting bolts, and the rear engine mounting base bracket mounting bolts, be sure to replace them with new ones.
Front Subframe Alignment
NOTE: Using the frame positioning guide pin, make the front suspension subframe alignment as the following sequence.
1. Make the front suspension subframe (A) alignment.
1. Lift the front suspension subframe up to the body, and loosely install the new subframe mounting bolts and the brackets (B).
2. Insert the alignment pin (C) into the alignment hole in the right rear of the subframe, and then align the subframe with the body.
3. Loosely tighten the subframe mounting bolt (D) until the lower insulator (E) contacts to the body at the right rear.
4. Insert the guide pin into the alignment hole in the left rear of the subframe, and then align the subframe with the body.
5. Loosely tighten the subframe mounting bolt (F) until the lower insulator contacts to the body at the left rear.
6. Insert the guide pin into the alignment hole in the right rear of the subframe, and then tighten the mounting bolt to the specified torque values.
7. Insert the guide pin into the alignment hole in the left rear of the subframe, and then tighten the mounting bolt to the specified torque values.
8. Tighten both front subframe mounting bolts (G) to the specified torque values.
9. Tighten all of the bracket mounting bolts (H) to the specified torque values.
2. Set the front suspension subframe middle mounting rubbers (I) on both sides, and tighten the rubber mounting bolts (J) that secure the rubber to the body to the specified torque values. And tighten both subframe mounting bolts (K) securing the subframe and the rubber to the specified torque values.
3. After reinstalling all removed parts, check and adjust the front wheel alignment.
Rear Subframe Torque
NOTE:
- When installing, align both installation reference holes in the subframe with the reference holes in the body using the frame positioning guide pin, and align both installation holes in the rear subframe mounting front stays with the reference holes in the body using the frame positioning guide pin.
- After removing the subframe mounting bolts, be sure to replace them with new ones.
