I'M HEARING A RESINATING OR VIBRATING SOUND(VERY LIGHT) FROM THE PASSENGER FLOOR BOARD. HAS ANY ONE EXPERIENCED THIS? I'VE CHECKED THE EXHAUST AND CHANGED THE FUEL FILTER.

Check to see if the exhaust is touching the frame cross member. That happened on my truck after I installed my 4". I only noticed it at idle or very low RPM. I had to adjust the hanger slightly...Problem solved.

I checked exhaust and thats not where it seems to be coming from. I think it may be something inside the oil pan. It's a harmonic tone sound, definitley coming from the oil pan/tranmission bell housing area. When I push on the oil pan it changes tone!?!?!?! Any suggestion would be appreciated.
