Axial Yeti XL Build – Part 4 – Rear Axle

The Build – Part 4
The Axial Yeti XL uses a little different rear axle than most vehicles. We’ll be building a solid rear axle that includes the diff from our previous step.

Build Notes:
Pay close attention to the installation of the outer carrier. These are directional and do need to be installed a certain way.
Step 1:
Axial Yeti XL Build – Step 41
Let’s start the rear axle by assembling the rear input shaft. Like the front, insert the CVD barrel into the joint and slide it into the 11T gear. Slide the pin through the holes in the gear and input barrel. Make sure to use a good amount of black grease to keep things lubricated.
Step 2:

Slide a pair of 15×18 washers followed by a 15×21 bearing, plastic spacer and second 15×21 bearing. These parts capture the CVD pin and prevent it from falling out.
Step 3:
Axial Yeti XL Build – Step 43
Set the gear assembly up on it’s side and slide the C-clip into place. Press the bearings/spacer/shims down firmly to seat them and, using needlenose pliers, carefully snap it into the groove, just like the front assembly.
Step 4:
Axial Yeti XL Build – Step 44
Here is what the assembly should look like. Just make sure the clip is completely seated in the groove.
Step 5:
Axial Yeti XL Build – Step 45
Mate the splined CVD to the splined end of the slider shaft. Press together firmly to make sure it’s completely seated and secure with the M3 flathead screw. A drop of threadlocking compound will help prevent this screw from backing out.
Step 6:
Axial Yeti XL Build – Step 46
Slide the slider assembly through the rear axle housing as shown and firmly press to completely seat the bearings into the recess.
Step 7:
Axial Yeti XL Build – Step 47
Secure the slider assembly with the 3 M2.6 screws. Like the front, make sure that the slider assembly is completely seated.
Step 8:
Axial Yeti XL Build – Step 48
Grab your differential and apply a good amount of the supplied grease to the gears. Press the diff into the housing and screw the rear axle cap into place.
Step 9:
Axial Yeti XL Build – Step 49
The instructions have you inserting both drive axles into the rear housing, but I actually found it easier to build them a little different. Start by sliding a 8×16 bearing onto each axle and then firmly pressing it into the outer carrier to square it up and completely seat it.
Step 10:
Axial Yeti XL Build – Step 50
Now slide that assembly into the rear axle housing. While pressing, rotate the drive axle to key the dogbone to the diff inside. Note the orientation of the link pickups to the rear axle; they should be pointing down.
Step 11:
Axial Yeti XL Build – Step 51
Secure the outer carriers with the M3 screws. I used a small driver to align the holes prior to installation.
Step 12:
Axial Yeti XL Build – Step 52
Attach the rear axle brace. Getting this piece to snap into place was a major pain. I found it easiest to install one end, secure with the two M3x25mm (only engage them about 5 or 6 threads in) and then flex the piece to pop the other end in. You can then insert the other M3x25mm screws and tighten down. Install the M3x10mm screw last.
Step 13:
Axial Yeti XL Build – Step 53
Slide the aluminum hexes onto the axles, insert the drive pin and secure with the M5 setscrew. Threadlocking compound is highly recommended here.

Once complete, rotate the slider axle a few times to make sure everything rotates smoothly. Time to move on to the front suspension.

  1. These directions for the Yeti XL Kit are great! Is there a way to get a printable copy of all of them?

    Thanks,

  2. Hi Bill. Thanks, this was a pretty big project; alot longer build that I had expected. Unfortunately I don’t have it in a PDF format for printing. Hopefully you’ll still be able to use them.

    Tony
