Ok i have an 2002 accord 2.3 F23a1 5speed. today i heard a poping noise when i let off the clutch in first and second. so i pulled the tire off (front Right) and crawled underneath and moved the axle back nad forth jerking it. well i can here the poping sound and feel it slightly in the bottom of the oil pan? (Motor is running fine) any ideas what that could be? Thanx
