PURPOSE: A bush system of mounting a trailing arm for a suspension in a vehicle is provided to improve performance by modifying the shape of an installation bracket, and to enhance handling by reducing impact and preventing a bush from being deformed against external force. CONSTITUTION: An installation bush(20) is composed of a first bush(22) and a second bush(24), and mounted in an installation bracket(26). A trailing arm(16) is connected to a control arm or a wheel carrier, and a front end(28) of the trailing arm is connected to the vehicle body with the installation bush. A radial protrusion(27) is formed in the installation bracket, and assembled with the first bush. A fitting hole(34) is formed in the middle of the first bush to insert the trailing arm, and a first groove(32) is formed around the fitting hole. The second bush is inserted to the front end of the trailing arm, and tightened with a nut(38) in inserting a washer(30). Tension force or compressive force is reduced with first and second bushes in braking or bumping. The vehicle is stabilized with preventing deformation of the first bush by assembling the first groove with the protrusion of the installation bracket.
