6. Remove two 3x15mm button-head screws from the differential
cover. Do not remove the two screws that secure the shock tower.
7. Use a 1.5mm hex wrench to remove the two screw pins that
hold the driveshaft yokes to the differential output shafts.
Remove the differential cover and slide the differential out of the
front of the case.
8. To reinstall the differential, reverse the steps.
Rear differential:
1. Remove the two 3x6mm flat-head sway bar screws.
2. Remove the two 3x20mm button-head screws that secure the
top bumper mount to the differential case.
3. Turn the chassis over and remove the two 3x12mm countersunk
crews that hold the bumper/skid plate to the bulkhead. The two
front screws do not need to be removed.
4. Remove the 3x20mm button-head screw from the bumper
mount and tie bar.
5. Slide the bumper assembly off of the chassis.
6. Remove the tie bar from the chassis.

8. Remove the differential cover and slide the differential out of the
front of the case.
9. To reinstall the differential, reverse the steps.
Refilling the differentials:
1. Remove the four 2.5x8mm screws from the differential case and
carefully pull the differential case halves apart. Work over a towel
to collect any fluid that drips from the differential.
2. Drain the fluid from the differential. You may wish to remove the
spider gears from the differential to make this easier.
3. Place the spider gears back into the differential case, if you
removed them. Fill the diff case with fluid until it the spider gears
are submerged half way.
4. Rejoin the differential case halves, using care to align the screw
holes. Be sure the rubber gasket is in place, or the differential
may leak.
5. Install the 2.5x8mm screws and tighten securely.
Center differential
The optional included center differential allows the power from
the motor to be transferred to the front and rear differentials
independently from one another. When the rear wheels are under
more load than the front wheels, more power will be transmitted to
the front wheels. This is very beneficial on rough terrain and makes
hard acceleration from low speeds easier to control by keeping
the nose down.
The center differential is assembled with 100K
differential lube from the factory. This viscosity will be a good base
point for most conditions.
1. Locate and remove the two 4x12mm button head machine
screws from the top rear of the chassis and the two 4x14mm
button head machine screws from the bottom of the rear
suspension bulkhead (See page 25 for reference).
2. Remove the modular rear end from the chassis by sliding it
backward away from the chassis. This is to access the spur gear/
slipper unit. Remove the spur gear/slipper unit from the rear of
the chassis.
