what would cause a two year old car bearings to go bad?
I have a 2018 Subaru Crosstrek. I just had it in for it's 36 thousand mile service. A week later the rear tires were making a humming noise. When I asked them what it was they said sometimes when they rotate the tires the treads can be the wrong direction. The noise did not go away. I just brought it in and they told me that both rear bearings had gone bad. They first told me this it is from driving over potholes. Then they told me it is from rust. What can cause the bearings to go bad on a two year old Subaru?
