I'm hearing low frequency hum/rumble that sounds like it's coming from the driver-side front wheel. I replaced the OEM Goodyear tires with Hankook Ventus S1 Noble2 tires in July 2015.

It will do this indiscriminately; after it sits for a week or two - it will start.

My car has had a clicking noise for a while now but it has now become almost a knock. Its been suggested its the Purge Valve and its been suggested I get a new engine. One dealer wouldnt perform the TSB because he knew I needed a new engine. Another said not so fast. I am afraid to drive the car now. Help!

what specific tools are needed to replace brake pads on this vehicle?

I am being told that I need rear brakes with only 19,000 miles. Is this possible so soon ?
