Vaterra Ascender K5 Blazer Build – Rear Axle

The Build – Part 3
The rear axle is very similar to the front. We’ll just give a brief overview of the build.

Build the rear center driveshaft like you did the front. Don’t forget to add a little bit of black grease to the inner coupler and threadlock to the coupler screw.

Assemble the rear axle using the same steps as you did in Part 2. Don’t forget the threadlocker on the screw securing the sun gear.

Slide the shims and the bearings on the rear spool. Again, your instructions might not show the shim but they do need to be on there.

Insert the rear driveshaft assembly and the black locknuts into the axle housing.

Drop the spool into the rear housing and add some black grease to the gear. Rotate the gear to spread out the grease.

Attach the chrome pumpkin cover (and lower brace) to the rear axle. Remember, the shorter screws go up top; the longer ones down low.

Attach the multi-link brace to the rear axle.

We will be using the same method to install the rear axle as we did the front. I found it much easier to assemble the rear axle prior to sliding it into the axle housing. Start by sliding a bearing onto the shaft followed by the axle housing cap.

Slide a second bearing on the axle followed by the wheel hex and through-pin. Build 2 of these.

Now slide the axle into the housing. Apply a small amount of pressure to get the axle as far in the housing as possible. Twist the center driveshaft until you feel the axle key into the spool.

Finally, use the 2 3x6mm screws to secure the axle cap to the housing. Do this for both sides.
