Driveshaft play and clunk

["Rick Hunt" <rhunt@sbs-ec.com>]

All:

The car in question is a '90 200q wagon and I've got a problem with 
the driveline. When pulling away from a stop there is a mild shudder. 
Also when you back off of the throttle, there is a delayed jerk on 
deceleration.

With the car on a lift, you can grasp the driveshaft just ahead of 
the rear differential and rotate it by hand.  The shaft will rotate a 
few degrees in both directions and you can feel and hear a metallic 
clunk.  The clunk seems to come from within the shaft.

Suggestions?

Thanks,
Rick Hunt
