there is a metal noise on the right front wheel, especially when the day is rainy.i've checked everything but all is ok......the only thing that i've not checked is the top bearing but i don't have noise when turning the wheels.......any suggestions?

I had this exact problem, it was when I turned right. The problem for me was the Driveshaft, the whole thing went and the car wouldn't move! It can be a pricey job so get it checked out. I hope this isn't the problem!
