Building Axial’s aluminum suspension and steering links isn’t tricky business, but if you don’t perform the task correctly, you can create problems. Follow these steps for perfectly built links.
The 3x16mm set screw (AXA186) threads into the plastic rod end, not the other way around in the threaded aluminum pipe. Threading the set screw in halfway is perfect, and there is no need for thread-locking compound.
To make sure you’ve threaded the set screw in to the correct depth, hold an uninstalled set screw next to the parts you’re assembling to visually see how far you’ve threaded the set screw in. If you don’t thread the hardware in deep enough, the set screw will easily pull out of the plastic. If this happens, the plastic rod end should not be reused. If you thread the set screw in too far, it can bind the ball in the rod end. Even if you back it out, you may have created a dimple inside the rod end and you won’t have the free movement that is desired for suspension and steering links. Also, if the set screw isn’t deep enough into the link, it may be prone to wobble.
You can make custom-length links by adding spacers or by joining aluminum links together. Two aluminum links can be connected using a set screw. Again, don’t use thread-locking compound. Instead, just snug down the pieces and the assembly won’t loosen once installed.
