I had the same thing, IJ told me to do this and it was my diff...jack up the back and put on your e-brake and tranny in neutral, then try and turn the driveshaft, if it moves excessively then your lash is coming from the diff.
While it's up there try putting the tranny in gear and e-brake off and doing the same thing too, if the lash is from your tranny that will show it.
Better off having a friend hold down the brake pedal to apply the disc brakes. The e-brake shoes have about 1/8" of rotational slop when they're applied. This will show up at the driveshaft as alot more slop. I figured this out when I checked my car on the 2 post lift one day, with the e-brake set, then checked it the next day on the 4 post lift (with the tires chocked). My diff was less... sloppy.

i think hes talking about the cross member that runs right under where the tranny meets the block.
Yeah, it's kind of more under the motor though, right? If that was missing it would probably make the car handle weird, but not cause driveline lash.
Easy way to tell if the trans is the problem. (Manual trans) See if the lash gets better in 4th gear, compared to all the other gears. If it gets a little better, that's normal. If it gets ALOT better, you've got bearing wear in the transmission. 4th gear is direct drive and the bearings have less effect on the lash since it doesn't use the countershaft bearings and loads the input/output shafts differently.
My trans does this (alloy plate W58). Straight weight 190 gear lube is holding it together. That and a clutch that hates launches and melts down at the suggestion of a clutch kick.
