the "M" clunk theory.
I was playing with my car the other day driving around. I started to notice the clunk sometimes. More so in low gears. It almost feels as if the driveshaft goes into neutral in between shifting. Engages when clutch pedal is let out. Just a idea. My eclipse, like so many other eclipses', had a rattle sometimes when it was started. Turn off, restart, no rattle
