Hello, when swapping out the hub caps on the wheels, I noticed that three wheels had the bronze metal behind the cap whereas the fourth wheel had a grey metal piece under the cap. Are they all supposed to be the same? Or am I missing 3 of the grey metal pieces.
Would have never noticed either till I rolled my windows down and I am hearing the exact same thing. Only on acceleration and below 20 mph that it is happening. Hopefully we get an answer for this soon!
