rattle 2002 EX
2002 Civic EX 5spd 106K
Tinny sounding rattle ONLY under load (accelerating) AND in gear. Not too loud, drowned out with radio on. Slightly louder in 1st/2nd/3rd gear - but maybe only b/c the RPMs are higher and as I go faster, harder to hear the noise.
Does not make the rattle if the engine is revved in neutral.
No noise from transmission while under no load (no acceleration, just cruising).
I really thought it was the heat shield but I went under the car today and they both seem very tight. There is a long piece of exhaust from the cat with only 1 support until the muffler - maybe that is the source. I don't think it is an input shaft bearing or a throwout bearing b/c the noise is not there unless the car is in gear and accelerating.
My 6th gen civic sounded kind of like this and it was the heat shield around the front of the HX cat - I just clamped it tight and solved the problem. No heat shield to even try to clamp tight on this EX. Maybe I'll just take the heat shields off - do you really need them anyway?
Transmission?
Bad cat?
Hopefully just exhaust rattle I can't find yet...
Ideas welcome....thanks
