ADVANCED TUNING ADJUSTMENTS
Rear differential:
1. Remove the two 3x20mm button-head screws that secure the
top bumper mount to diff case.
2. Turn the chassis over and remove the two 3x12mm countersunk
screws that hold the bumper/skid plate to the bulkhead. The two
front screws do not need to be removed.
3. Remove the 3x30mm button-head screw from the bumper
mount and tie bar.
4. Slide bumper assembly off of the chassis.
5. Remove the tie bar from the chassis.
6. Remove the two 3x15mm button-head screws from differential
cover. Do not remove the two screws that secure the shock tower.
7. Remove the differential cover and slide the differential out of the
front of the case.
8. To reinstall the differential, reverse the steps.

Refilling the differentials:
1. Remove the four 2.5x10mm screws from the differential case
and carefully pull the diff 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 diff case, if you removed
them. Fill the diff case with fluid until the spider gears are
submerged half way.
4. Rejoin the diff 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 2.5x10mm screws and tighten securely.
TORQUE BIASING CENTER DRIVE
The Torque Biasing Center Drive 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 drive is assembled with 500K
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 4x12mm
button head machine screws from the bottom of the rear
suspension bulkhead.
2. Remove the rear suspension assembly from the chassis by sliding
it backward away from the chassis.
3. Remove the center drive assembly. Refer to the exploded views
included in the Service and Support Guide for a complete
assembly diagram.
4. To reinstall the center drive assembly, reverse the steps.
Tip: Rotate the rear wheels slowly while attaching the rear
suspension assembly to the chassis to properly set the rear output

shaft of the center drive into the rear differential. You should feel
the rear end set into place. The rear skid plate should lock into the
bottom of the chassis.
