PURPOSE: A ball joint assembly for a suspension of a vehicle is provided to prevent deformation of a stabilizer caused by inaccurate welding position and scattering of welding portions by combining a lower arm and the stabilizer with a joint unit for uniting a ball joint and a sub ball joint at the same time. CONSTITUTION: A joint unit(10) combines a lower arm(2') joined to a vehicle body by a bush at the lower side of an upper arm(2) between the vehicle body and a knuckle mounted with a vehicle wheel to the knuckle of the vehicle wheel and comprises a ball joint(11), a case housing(12), and a sub ball joint(13). One end of the ball joint is fixed to the knuckle. The case housing comprises a spherical ball head receiving unit(12a) disposed at one end of the ball joint, which is not fixed to the knuckle, to receive and support a ball head; a fixing body(12b) integrated to the ball head receiving unit and formed with a bolt hole joined with the lower arm; and a sub ball head receiving unit(12c) extended from the fixing body to space from the ball head receiving unit at 90 degrees and formed with a spherical projection unit for combining the sub ball joint fastening a stabilizer(3). The sub ball joint is combined to the case housing and united with the end of the stabilizer.
