10 mm bolts on the supercharger cover with a
socket and extension.

threads on each nut. Do not remove the nuts
from the studs.
NOTE: If you are using a vehicle hoist, lower
the vehicle back down so you can now work in
the engine compartment area.

extension, remove the sway-bar bushing to
cradle bracket bolts (2 per side) and then
remove the brackets from both sides. Allow the
sway bar to swivel down but do not remove the
sway-bar.

engine cradle retaining nuts on both sides.
