There is some play in the transmission, and some play in the rear end. The combined slack will allow you to twist the driveshaft about 1/2" or so. If you are under there looking at it, you just want to be sure ther isn't any play in the u-joints at either end of the shaft.
Did you check the computer for codes?
Have you changed anything lately?
Are you current on your maintenance? Spark plugs, air/fuel filters, plug wires...
