The bushing is then pressed into the hole of the control arm using a hydraulic tool. This operation is affected by vibrations caused by the person holding the bushing, and the position of the bushing in the hole is easily deviated, resulting in significant wear of the bushing along the hole wall during the insertion process, which is quite inconvenient.
