Important!
• When reinstalling the rear suspension module, ensure that the center driveshaft
adapter is installed into the torque biasing center drive unit. If the adapter is not seated
properly, it will not connect to the center driveshaft (the vehicle will be rear wheel
drive only). Ensure that the center driveshaft passes through the felt driveshaft bushing
without damaging or dislodging it. The driveshaft will pass through the bushing easily if
it is positioned correctly. If the bushing moves out of its slot, disassemble the bulkhead,
reposition the bushing, and reassemble.

• When reinstalling the motor, ensure that the gear mesh pins are in the correct locations
(refer to the pin location chart on page 24). Place the motor onto the rear bulkhead and
install the gear cover with the 3x10mm cap screws (2). This will allow the truck to be
flipped upside down and still maintain proper gear mesh. Flip the truck upside down and
install the 4x16mm button-head cap screws (4) into the motor mount.
