Mysterious scraping sound while backing up.
Figure this one out.
Problem:
Repetitive metallic scraping noise
Happens when:
Car is moving backwards with clutch engaged.
Does not happen while coasting backwards, only with clutch engaged. Doesn't seem to be transmission related becuase the frequency of the noise is not fast enough to equal the rpm of the input shaft or transmission output. The frequency sounds like it matches rpm at the wheels, but again, it does not happen when I am just coasting backwards, only when under power.
VERY CONFUSING
Anyone experience this before?
