Had a horrible noise yesterday that turned out to be rust from the disc protector flaking off and sitting between the protector and disc. Truly horrible noise.
But while the wheels were off i found that there is a bit of rub on both sides (rear). Is this normal for car wheels, i could still turn the hubs by hand and when the wheel was on they turned but with a what seemed like resistance.
Is it normal to have a little rub? Thinking back i am pretty sure that i've always found car wheel to rub a bit but i'm not sure.
