Any updates from anyone here? I'm taking my car in tomorrow to have it looked at. I'm going to ask that they check all of the following:

-Loose or Broken Differential Bolt (maybe axle bolts on diff output flanges or the drive shaft bolts on the diff input shaft, under the heat shield)
- Check diff bushings for excessive wear/cracks; replace bushings if damaged
- Check that exhaust mounting brackets aren't broken, since they can be damaged/broken depending on how the diff bolt breaks
- If other parts are broken, confirm no damage to the rear subframe.
- Failing Driveshaft (also, check the center support bearing and housing, halfway up the driveshaft)
- Failing Differential
- Unlikely the problem, but something to try (SI B33 04 08)
