When I leave a stop sign (or from a complete stop) under normal acceleration I hear and feel a clunk. It sounds like it is coming from the rear end, but I don't know. If I idle away from the stop for about 5 - 10 feet, then accelerate VERY slowly the clunk won't happen, but under normal or hard acceleration it is there. Has anyone else had this problem? I am going to take it to my transmission guy, but I just wanted to ask. |

Sounds like a ujoint or the slip yoke in the driveshaft to me. If either of these are bad, you'll have a little "play" in the drivetrain so when you first take off quickly, you'll hear a "clunk" sound.
The tranny guy will get things squared away for you. Let us know what it was when you find out!
