On a 2002 ranger I have a can about the size of a soup can under there on a bracket.Is that some sort of an anode for corrosion or what? No one seems to know if it for corrosion or vibration or what.I have noticed it servicing it and I'm sure there are no wires or anything on it.I can ask the dealer when I go sometime but the last time I didn't ask a mech but the office guys were clueless.
