I had to retype my long posting after refreshing the page...
I was driving towards Orchard on Friday(31 August 2013) when I began to hear a consistent drumming sound on the left side of my car after a jerk. I stopped to check but the sound stopped when the car is idling. I googled to find relevant postings on similar experiences and one of the links led me to this forum. Thanks to the forum creator! I read the rave reviews on Kelvin's service and called him. He showed great patience in eliciting information from me and diagnosing my car problem. We concluded that a nut must have lodged in the tyre. So an appointment was made. Impressed by his unassuming disposition, I asked if he could do car servicing as well on Monday(2 Sept 2013). He agreed.
However, when I drove my car out on Saturday(1 Sept 2013), the nut was dislodged from the tyre and I ended up with a punctured tyre on a busy road.
