NOTE
To ease installation and ensure that the
bushings will not move during reinstallation,
use masking tape to hold the inner bushings
to the lower support.
14. Install CAC on the vehicle and secure to the
lower support using both lower hex bolts,
washers and remaining plastic insulating
bushings.
TORQUE: 9 lb-ft (12 Nm)
WARNING
To prevent galvanic corrosion, the CAC is
electrically insulated from the support by the
use of plastic insulating bushings.
When reinstalling brackets, make sure the
plastic insulating bushings (two per bracket) &
washers (one per bracket) are present and in
good condition (replace as necessary).
After installation, check for proper insulation
(lack of conductivity) between support and
CAC body with a suitable ohmmeter or
continuity tester (buzzer).
15. Reinstall both (upper and lower) front frame
sections.
16. Secure
structure.
