I hear a clicking sound in the back end of my 2002 Explorer. It seems to happen when I go over a small bump or uneven pavement. Any ideas?
Also, my fuel cap light is on, I have replace the cap (with a ford replacement) and the light will not go off. I reset it and completed the "two drive cycles" and it's still on
I would guess that the clicking noise you mention is either the shock absorber showing signs of wear or possibly the exhaust has come loose and it vibrates when you go over a bump. There are two possibilities why the warning light is still on, either the new part is not quite fitted correctly or the warning light sensor needs replacing. I'm sorry, I don't know the answer to your last question.
