Abstract
Wishbone-style control arm assemblies for a vehicle and methods for assembling the same are disclosed. A control arm assembly includes a first elongated segment having a first connection feature at one end of the first segment. The control arm assembly includes a second elongated segment having a second connection feature at one end of the second segment. Opposite longitudinal ends of the first and second segments may include third and fourth connection features, respectively, that are configured to interface with the vehicle. The first and second connection features are aligned to form an aperture that extends at least partially through the first and segment connection features, through which a bushing is press-fit and then swaged to form a strong connection that reduces or eliminates the need for mechanical fasteners or adhesive bonds. The bushing connection independently enables the control arm to maintain a secure connection between segments during operation of the control arm when assembled in the vehicle.
