Front and Rear Disassembly/ Plastic Half Shaft Removal
Front disassembly and differential removal:
1. Using a 7.0mm wheel wrench,
remove all four wheels from the
axles.
2. Disconnect the front body mount
by removing the 3x6mm button
head screw and the two 3x10mm
button head screws (A1).
3. Remove the front shocks from
the chassis by removing the two
2.5x18mm cap head screws from
the upper shock mount and the two 2.5x10mm cap
head screws from the rocker arms (A2).
4. Next, remove the two 3x10mm button-head screws
located underneath the two front shocks (A3).
5. Flip the chassis over to disconnect the steering servo
link by removing the ball screw
from the bellcrank (A4). The entire
front end assembly can now be
removed from the chassis.
6. Remove the 3x10mm screw pin
from each output yoke attached
to the differential (A5), and pull
the yokes from the differential
(diff).
7. Remove the four 2.5x8mm cap
head screws and the 2.5x12mm
countersunk screw from the
front skid plate (A6). Remove the
2.5x6mm cap head screw from
the front bulkhead brace (A7);
then, pull the brace and the skid
plate from the front end.
8. Separate the front bulkhead halves to access the differential and pinion gear.
Remove the diff and the pinion gear from the bulkhead (A8).
9. Remove the wheel hex adapters from the front axles using the tip of a small
flat-blade screwdriver; then, slide the drive pin out of the axle (A9). Next, slide
the plastic half shaft assembly out of the hub carrier (A10).
Note:
The wheel
bearings should stay inside of the hub carrier.
Rear disassembly/differential removal:
10. Remove the 3x8mm button head screw
and the two 3x10mm button head
screws from the rear body mount (B1).
Loosen the two 2.5x14mm (1/16 Slash) or
2.5x12mm (1/16 E-Revo) cap head screws
from the rear bumper (B2), and pull the
rear bumper assembly away from the
chassis.
11. Remove the rear shocks from the chassis
by removing the two 2.5x18mm cap
head screws from the upper shock
mount and the two 2.5x10mm cap head
screws from the rocker arms (B3).
12. Next, remove the two 3x10mm
button head screws located
underneath the two rear shocks
(B4), and then flip the chassis
over to remove the center skid
plate from the chassis.
13. Remove the four 3x8mm button head screws, two
3x10 button head screws, and the two 3x15mm
button head screws from the center skid plate (B5).
Remove the center skid plate from the chassis; then,
slide the entire rear assembly away from the rear of
the chassis (B6).
14. Remove the 3x10mm
screw pin from each
output yoke attached to
the diff (B7); then, pull the
yokes from the diff.
15. Remove the four 2.5x8mm
screws from the rear skid
plate (B8), and pull the rear skid plate and the rear
bulkhead brace off of the rear assembly (B9).
16. Separate the rear bulkhead halves to access the diff
and pinion gear. Remove the diff and the pinion gear
from the bulkhead (B10).
17. Remove the wheel hex adapters from the rear axles
using the tip of a small flat-blade
screwdriver and slide the drive pin
out of the axle (B11). Next, slide the
plastic half shaft assembly out of the
hub carrier (B12).
Differential Disassembly and Differential Cup Installation
18. Remove the three 2x14mm
button head screws from the
diff case (C1); then, separate
the diff covers from the ring
gear (C2).
19. Remove the output shafts
from each diff cover (C3). Next,
remove the output gear, drive pin,
and O-ring from each output shaft
(C4).
Note:
The stock output shafts
will not be reused.
20. Locate the steel diff cups
(included) and insert one into each diff cover; then, slide
an O-ring onto each diff cup shaft, as shown (C5).
21. Insert a drive pin into each diff cup shaft (C6) followed
by the output gears (C7). The gears should key onto the
drive pins.
22. Install the diff cover that goes
to the ring gear side of the diff,
making sure the three diff screw
holes are aligned and the O-ring is
properly seated. Next, make sure
the spider gears are located in
their proper positions inside of the
housing, and fill the diff housing
with the desired diff fluid.
23. Place the other diff cover onto the diff assembly,
making sure the three diff screw holes are aligned
and the O-ring is seated correctly. Secure the diff
assembly with the three 2x14mm button head
screws (C8).
Front and Rear Assembly/ Metal Driveshaft Installation
Rear assembly:
24. Locate the two metal driveshaft assemblies,
and slide the axles through the inside of each
of the rear hub carriers, as shown. Make sure
to seat the axles into the ball bearings. Install
the drive pins and the wheel hexes onto the
axles to keep them in position (D1).
25. Position the rear pinion gear assembly into
the right-side bulkhead half (D2). Install the assembled differential (D3) into
the bulkhead half. Insert the driveshaft into the diff cup (D4).
