Sounds Like U Joints

[Luva65wagon]

Ah - the infamous "CLUNK!" Not a moving noise.

Well, that can be a few things, but the two most common (aside from u-joints) are a worn tailshaft bushing and excessive ring and pinion play. It can also be simply due to too high an engine idle speed.

If you have a friend who can demonstrate it while you [safely] watch what and where the noise emanates from while on the outside looking under the car. Don't be under the car... of course. You might be able to pin-point front or back of the car better. You can also put the car up on jack-stands to get a closer look.
