My 90hp Punto was in the A.S.S. for rear wheel bearing fault. Got a call from SA that my rear dead axle is due for upgradation. So he is getting that done for me car. Mine is a Jan '11 manufactured car. I will post the differences observed after I get my car. He said he will try to deliver my car today evening itself. I am expecting/hoping that the thuds observed on potholes & speed breakers will vanish.
