You have not heard this one yet

So my car keeps deciding to drop drive train parts. First it was the driveshaft bolts, no matter what I did I couldn't not keep the car from throwing them. No matter how much thread lock or torque. Then yesterday I had to pull over because of a horrible grinding noise and found that all of the differential bolts had fallen out causing the diff to drop. What the hell is going on! The car doesn't have any vibrations, or didn't until the diff fell out.

Any ideas.

Is the drive shaft properly balanced etc? Thats really the only thing I can think of besides locktite.

tack weld the bolts in place :)

You pissed off an e46m3 owner and they are undoing the bolts/nuts on your car when you aren't looking ? LOL

check your flanges on the output shaft of the tranny and the input shaft of the diff. If the holes are out of round you might have found your culprit. Ask me how I know :) Somebody though it was fun to reuse old nuts on the bolts on my beater.
