Ok, I got my SO-2 two weeks ago not right... After few problem with balance.. I took it to other place where they can see and check the vibration with wheels on the car. Fixed! Last nite... on 101S as soon as I get on freeway.. I feel hard vibration coming from my right front and as they heat up no more on my steering wheels but I could still feel it on my right leg as that vibration felt thru body of the car. Anyone can throw me a guess what it might be or had similar experience?
