Covers Part #5551X
Remove the rear wheels and hex hubs
1. Remove the two 4.0mm nylon
locknuts from the rear wheel axles;
then, remove the wheels (A).
2. Slide the hex hubs off each axle, and
remove the axle pins (B).
Remove the rear shocks
3. Disconnect both rear shocks from the
chassis by removing each of the upper
3x15 button-head machine screws
from the shock towers, and each of
the lower 3x18 button-head machine
screws from the lower suspension
arms. This will provide better access to
the half shafts (C).
Remove the half shafts
4. Remove the M3/12.5
yoke pin from each
differential output shaft
(D1) and disconnect
the half shafts from the
output shafts (D2).
5. Pull the half shaft yoke off the output shafts coming from the
differential; then, pull the axles out of the stub axle carriers. Set
the half shafts aside. The yoke pins and half shafts will not be
reused (E1, E2).
Remove the differential
6. Remove the four 2.5x10 cap-head machine
screws that secure the rear battery cover,
and lift the cover from the battery box (F).
7. Remove the two 3x10
button-head machine
screws from the diff
cover (G) and the two
3x15 countersunk
machine screws from
the bottom of the
chassis (H).
8. Pull the battery box and diff cover
assembly from the transmission to
access the differential. Remove the
differential from the transmission (I).
Exchange the output shafts in the differential
9. Remove the four 2.5x8
countersunk machine screws
from the differential assembly
(J1), separate the side cover
plate from the differential
gear, and drain the differential
gear of all diff fluid (J2).
10. Remove the spider gears and shaft from
the differential gear. (Take note of the
orientation of each before removal.) Remove
the stock output gears from the differential
gear and the side plate. Also, remove the
blue X-rings, 5x10x0.5 PTFE washers, and the
differential gear gasket from the differential
gear and side cover. These will be replaced
by those in the kit (K1, K2).
11. Locate the two CV driveshaft assemblies
from the kit. Make sure the bearings are still
on the diff carrier before reassembly. Insert
the end (with the two flats) of one steel
driveshaft assembly into the differential
gear. Insert the end (with the two flats) of
the other steel driveshaft assembly into the side cover plate (from the
outside). See (L) for correct orientation.
12. Slide an X-ring over each shaft from the inside of the differential gear
and side plate cover (M1). Follow the X-ring with a 5x10x0.5 PTFE
washer (M2). Then, slide an output spider gear on last (see M3 for
correct orientation). Make sure that the X-rings are properly seated
into their grooves. Press the spider gear down onto the shaft and snap
a 1.5mm E-clip onto the end of the shaft to retain the gear.
13. Return the spider gears and the spider gear shaft
to the differential gear. Align the shaft ends with
the slots (N).
14. Fill the differential gear with the desired diff lube
(stock lube is 10K weight differential oil, Traxxas
part #5135). Place a new differential gasket
(included) onto the differential gear. Align the
four holes in the gasket with the four holes in the
differential gear. Reconnect the differential side
cover to the differential gear, aligning the same
four holes from the gear with the four holes in the
side cover (O).
15. Secure the differential gear and the side cover
together with four 2.5x10 cap-head machine
screws (P).

Install the differential and driveshafts
16. Insert both axles through the
bearings located in the stub
axle carriers one at a time (Q),
and place the differential back
into the transmission (see “R”
for correct orientation).
17. Attach the differential cover to the back of the transmission. Make
sure that the suspension pins are in the blue rear toe plate, and
secure the cover with two 3x15 countersunk machine screws
(S1) and two 3x10 button-head machine screws (S2). Secure the
battery cover to the battery holder with four 2.5x10 cap-head
machine screws (S3).
18. Attach the rear shocks to the suspension
arms with two 3x18 button-head machine
screws and to the shock tower with two
3x15 button-head machine screws (T).

19. Insert the axle pins into the holes in the
axles, and slide the hex hubs onto the
axles (U). Attach the wheels on the hex
hubs. Make sure the hex hubs are keyed
into the wheels and secure the wheels
with two 4.0mm nylon locknuts.
Steel CV driveshaft maintenance
The driveshafts are lubed and sealed at the factory and are built to
last. While the maintenance intervals are much larger with the sealed
shaft joints, it is still important to provide regular maintenance to
ensure long life. Follow the steps below for proper maintenance:
After every gallon of fuel*:
1. Pull the dust boots toward the middle of the shaft to inspect and
clean the inner and outer shaft joints. Clean the joints and dust
boots with denatured alcohol.
2. Inspect the drive cups, driveshafts, and dust boots for wear.
3. Lube the driveshaft joints with Traxxas thrust bearing lube (Part
#2717).
4. Push the dust boots back over the joints. Make sure the boots fit
snug around the joint.
* If running in sandy or dusty conditions, perform these steps after every half gallon.
