Recently when I first drive in the morning to take my daughter to school, I notice a scraping noise from the front once I reach 25 - 30 mph. It is a knocking sound that seems to vary with my speed, as if something was stuck to my tires and was rubbing against something regularly as the tires rotate. But there's nothing stuck to my tires. The sound persists up until I get on the freeway and disappears around 60 mph. Just over the last couple of days, the scraping sound gets much worse when I am making a tight right turn going downhill.
The sound seems to go away as the day gets warmer and I've been driving a while. Only seems to happen when I first drive it in the morning, at the coldest part of the day (65 - 70 degrees - I live in the tropics).
FYI, a few months ago I had my brake discs and pads replaced, but not by the dealer. I went to the auto parts store for the discs and pads and had my neighborhood mechanic install them instead. A friend of mine said perhaps the noise is because the brake discs and pads I had installed were not to manufacturer specifications? Does that sound right to you guys? The noise didn't start until weeks after the new discs and pads were installed, though. The research I'm doing seems to suggest that there are many possibilities, including CV joints.
Your help appreciated.
have the same problem?
