Understanding Control Arms: The Suspension Budapestmp; # 8217; s Backbone

Control arms (also called A- arms or wishbone) are pivoting suspension links that connect the vehicle vehicle connemple; # 8217; s frame or subframe te thee steering knuckle or wheel hub.

Each control arm contains bushings attachment points andd, on thee lower front arms, a ball joint that connects to thee steering knuckle. Over wintenr, these rubber or poliurethane bushings stiffen, crack, or separate frem the metal sleeve, while ball joints lose graase and develop play. Understanding these contents helps you diagnoze problems early.
