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).
