The Build – Part 3
Tackling the front (and rear) suspensions are a little more involved that most of the other steps with this build. HPI has made it quite easy though and you should not have any problems.

Build Notes:
Pay close attention to the hinge pins and the camber pins. The hinge pins are the thicker pins and you will use them in Step 35. The camber pins are thinner and you will use them in Step 42.

You will be building a left and right side of the suspension, however I will only be showing one side of the build.

We start off the build with the CVDs. Put a bit of black grease on the cross joint and push it through the axle as shown. A set screw threads into the cross joint, but only from one direction (or the open end). Make sure you insert the cross joint with the ‘closed end’ first. This will avoid getting any grease on the threads.

Apply a liberal amount of black grease on the axle ‘ball’ and insert it into the axle. Take your cross pin and insert it as shown. Make sure to line up the flat spot with the ‘open end’ of the cross joint.

Grab one of the steering blocks and insert a ball end and locknut as shown. We will be building two of these so do the same thing for the opposite side (you will need to build it as an opposite side, also).

…and the front. They are both the same so don’t worry about getting them mixed up. Now slide the suspension arm assembly between the arm mounts and feed the long hinge pin through. Yes, it might be a bit tight, but as long as the completed assembly swings freely you’re ok.
