When going at low speeds (up to about 10-15 mph) I can hear a popping sound coming from the rear end of my 02 SS (stock rear end). It's related to the speed I'm going...the faster I go, the faster the pop pop pop popping sound is, up until about 15 mph or so, anyways. I can't tell exactly where it's coming from, however, I can tell you it has nothing to do with turning/going straight. It just seems to happen when I'm puttering around, less than 15 mph. If the sound exists at higher speeds, I can't hear it for the rest of the noise.

So my question is this - this weekend I plan on jacking my car up and crawling underneath to see what I can find. Do you guys have any suggestions on where to start? I don't think it's the u-joint, as it doesn't clunk when going from drive to reverse (but I'll check it regardless). Suggestions?!?

 

won't hurt to pull your diff cover off just to make sure.....

 

sounds like your torsen unit is starting to go.

Mine does it in reverse after driving it a bit, and in forward if I've been getting on it real hard.
