Axial EXO Terra Build – Part 3 – Rear Gearbox/Suspension

The Build – Part 3
Part 3 revolves around the rear gearbox and suspension. This is a pretty straighforward build.

Build Notes:
The rear gearbox and suspension is much like the front. The same steps will apply.

Grab the second gearbox half that you built early on. If you didn’t put any grease on the input gear, do so now.

Insert the differential and attach the outer case half. Note the direction of the differential.

Attach the rear shock tower as shown.

Assemble the two rear uprights by installing the bearings and outdrives. They uprights are the same on both sides so there is no need to worry about a left and a right piece. Don’t worry about attaching the dogbones; they’ll only get in the way. We’ll insert them later.

Attach the shock mounts to the rear suspension arms. Note the orientation; the piece should ‘curve’ towards the inside of the arm.

Attach the rear uprights to the suspension arms. Make sure you install the spacers on the opposite side of the arm than the shock mounts.

Press the hinge pin inserts into both arm mounts and attach the R2 hinge pin mount to the back of the gearbox. Slide the hinge pins through the arms and insert into the rear hinge pin mount. Align and attach the R1 hinge pin mount to the front of the rear gearbox and secure. Rotate the arms up and down to make sure there is free movement. You don’t want any binding in the suspension arms.

Build a pair of turnbuckles and insert the bushings. Axial’s 48mm setting is spot on.

Attach one end of the turnbuckle to the upright. Slide the dogbone into place and attach the other end of the turnbuckle to the rear shock tower. Go ahead and use the attachment locations provided by Axial.
