Installing
Installation is in reverse order of removal, note the following:
- Tighten bolts for subframe only to specified torque. Do not tighten further (tighten bolts only after axle alignment).
CAUTION!
Vehicle must not be driven in this condition.
- Install air spring dampers.
- Install stabilizer.
- Install right intake manifold side part => [ Right Intake Manifold Side-Section ] Right Intake Manifold Side-Section.
- Install strut tower brace.
- Deactivate vehicle lifting mode.
- Perform axle alignment.
CAUTION!
After axle alignment, tighten subframe bolts to final torque.
