Only the PerfPk SHO, the XSport and the Flex get the PTU with the drain plug (not sure about MKS). Also vehicles in the Middle East. But the vent extension to the engine bay should still be there.
The shock absorber would drop out if you simply said BOO loud enough.
Removal and Installation
NOTICE: Suspension fasteners are critical parts because they affect performance of vital components and systems and their failure may result in major service expense. New parts must be installed with the same part numbers or equivalent part, if replacement is necessary. Do not use a replacement part of lesser quality or substitute design. Torque values must be used as specified during reassembly to make sure of correct retention of these parts.
NOTE: Use the hex-holding feature on the stock rod nut to prevent the shock rod from rotating when removing or installing the shock rod nut.
Pull back the luggage compartment side trim panel to gain access to the shock absorber upper nut.
NOTICE: Do not use power tools. Tighten using hand tools only. Failure to do so will result in shock absorber damage and/or Noise, Vibration and Harshness (NVH) concerns.

To install, tighten the new nut to 55 Nm (41 lb-ft).
Remove the wheel and tire. For additional information, refer to Section 204-04 .
