The Build – Part 6
Step 6 involves assembling the rear suspension. The build is very similar to the Step 3 (the front suspension), but thankfully has a few less steps. Lets get to it.

Build Notes:
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.

Apply a dab of threadlock onto the set screw and insert it as shown. Make sure the set screw contacts the flat spot of the cross pin. Build two of these.

…then slide the arm between the arm braces and slide the long hinge pin in place. If the arm does not slide in smoothly, loosen the arm mount brace screws 1/4 turn and try again. You want the arm to slide in but still have a somewhat tight fit.
