Abstract: A stabilizer bar bushing assembly is provided, in which even though it is exposed to heat of high temperature for a long time period the bracket is not dislocated from the rubber because the bracket is attached to the rubber integrally. The stabilizer bar bushing assembly comprises: an upper body including an upper rubber formed with a first concave groove and an upper bracket enclosing an outer surface of the upper rubber and bonded integrally to the upper rubber; a lower body including a lower rubber formed with a second concave groove and a lower bracket enclosing an outer circumferential surface of the lower rubber and bonded integrally to the lower rubber; and a coupling means for coupling the upper bracket and the lower bracket together in a state of installing the upper body and the lower body on the stabilizer bar.
