Axial EXO Terra Build – Part 4 – Center Differential

Axial EXO Terra Build

Scale vehicles have become the hot ticket lately. They not only look like their full-scale counterpart, but also perform like them too. Axial has just released their awesome EXO Terra buggy, a 1/10 scale buggy complete with roll cage, interior and other realistic parts. In my opinion, this is the thing our industry has been waiting for. Follow along as I build one for you complete with helpful hints.

Build Notes:
The center differential build is much the same as the front and rear diffs. Having some clean towels handy will help with clean up.

The Build – Part 4
In part 4, we assemble the center differential. Depending on the power you plan and running through your EXO, you can change this oil to help balance the front/rear drive ratio.

Axial EXO Terra Build – Step 40

Slide the red o-rings over the outdrives. A dab of diff fluid will help keep them lubed.

Axial EXO Terra Build – Step 41

Press the bearing onto the differential housing. It should be a snug fit and should sit flush as shown.

Axial EXO Terra Build – Step 42

Insert an outdrive through the housing and slide another red o-ring over outdrive.

Axial EXO Terra Build – Step 43

Align the flat spots on the outdrive and spider gear and slide the gear into place.

Axial EXO Terra Build – Step 44

Snap the e-clip into place. As we did with the front and rear diffs, a dab of diff fluid will help keep the e-clip in place while you lock it to the outdrive.

Slide the small spider gears over the input shaft as shown…

…and drop it into place within the diff housing. Rotate the outdrive to seat the gears if they don’t push all the way into place.

Axial EXO Terra Build – Step 47

Press the bearing onto the diff gear as shown.

Axial EXO Terra Build – Step 48

Flip the diff gear over, insert the other outdrive and slide the red o-ring into place.

Axial EXO Terra Build – Step 49

Align the flat spots on the outdrive and spider gear and slide the gear into place.

Axial EXO Terra Build – Step 50

Snap the e-clip into place. This side is much easier to work with so you probably won’t need the diff oil to hold the e-clip in place.

Axial EXO Terra Build – Step 51

Press the diff gasket into place as shown. If it slides off, a dab of diff fluid on it should help keep it in place.

Axial EXO Terra Build – Step 52

Fill you differential to about 85% with the provided fluid. Rotate the outdrive a couple turns to help circulate the diff fluid thoughout the housing. Let it stand for a minute or so and then refill to about 90% with the fluid.
