2010 c350 4matic noise from fron end at 25km p/h
at first I thought snow stuck in the wheel w. and then I thought warped rotor? because the sound noise it makes.I have taken it to a benz mechanic and told me that i have cupped tires,,,, dws contis less than 30 km.
but I have a feeling that the noise is metal on metal but from where I dont know and I am hoping you guys can point me in the right direction.
Thx
