Thanks a lot. I was trying to make it look like it was supposed to be there and not like someone cobbled it together in their barn.
A four link is just the term for how the axle is connected to the frame. There are four links all in a relatively straight line. There is actually a fifth link, the track bar, which locates the axle from side to side. There is some argument as to whether it is actually a 4-Link or 5-Link in stock form. I can't remember the general answer.
However, usually, nowadays when someone says "4-Link," he or she is usually describing the removal of the track bar from the system. This necessitates some way to locate the axle laterally. This is where the triangulation comes in. Take either the two upper arms or the two lower arms and triangulate them so they either meet over top or beneath the differential housing or on the other side. A little more to it, but that's it in a nutshell. Getting rid of the track bar results ina smoother ride and less binding. Generally speaking.
