I was driving around in first gear dodging pedestrians in our local park. very low speed less than 1500 rpms. Finally I got past all the people and punched it to about 2500 had to make a turn and got off the gas heard this clunk that yanked the car a little. So I immediately pulled over and looked I couldn't see anything from under the hood. So I got back in the car and started driving around the parking lot very low speeds again this clanking seems to be louder when I am decelarating in gear between 40 and 10 mph. Gear does not matter, speed does determine the pace of the clanking. I do feel it in the shifter. Turning does not effect the noise. It does also make the noise very quietly when not in gear and seemingly only when slowing down. I'm thinking I broke an axle? kinda hoping thats all it is. I don't see anything under the car that could be rubbing any rotating parts of the car. Freakin laid in gum looking for something under the car but I see nothing abnormal, no leaks of any sort. no parts were lying around or seem loose. Any ideas?
