I have a used honda civic 2006 exi prosmatic. Recently I went to Islamabad on motorway and during high speed I noticed that my car started to vibrate from left front side at a speed around 120 to 130 KM/Hr. Apart from this speed there was vibration but reduced very low. Before starting the trip I balanced all four tires which are almost new. Also completely overhauled the front suspension and changed rubber bushes, ball joints, front shocks with mountings. Please advice me from where I should got check my car to pin point the fault without experiments and wasting time. I am from Lahore.
