Step 1:
Assemble the heim joints, jam nuts, misalignment spacers, and links in the same order and orientation as the image below. The left-hand threads will be marked with a machined groove on the end of the link and on the hex of the jam nut for easy identification. Take care to install the misalignment spacers on the correct end of the link assembly. Step 2:

One at a time, remove the existing control arms and replace them with a new control arm. The control arm length can be adjusted if the heims are held stationary and the link is turned.
