Multilink is a suspension architecture in which each wheel is located by several separate links, typically four or five, rather than by two-piece control arms. Because each link constrains one degree of freedom, the designer can place the pivots to control camber, toe, caster, anti-dive and anti-squat curves largely independently of one another, which is difficult with a strut and constrained with a simple double wishbone. That freedom is the design advantage; the costs are packaging complexity, more joints and therefore more bushing compliance in the load path, higher part count and greater difficulty in analyzing or modifying the geometry after the fact. The term is also applied loosely to solid-axle rear suspensions with several locating links, which is a different arrangement since the two wheels are not independently located.
