CAUTION:

For the non-reusable parts, always use new parts.
Always tighten the bushing in the state where the vehicle is at curb weight and the wheels are in full contact with the ground.

Check the removed parts for wear, damage and crack, and repair or replace them if faulty.
Install each part to the sub frame assembly rear.

Install the rear suspension assembly.
1. Lift the rear suspension assembly using a transmission jack.
  NOTE:
  - Since the rear suspension assembly is heavy, make sure that it is firmly supported so that it is level.
  - While checking there is no dragging of harness, raise it slowly with a transmission jack.
2. Install the support sub frame front and the support sub frame rear, and temporarily install the rear suspension assembly.
  CAUTION: Always use a new flange bolt (a).
3. Tighten the bolts in the numerical order as shown in the figure.
4. Tighten the support sub frame front.
