. It might be obvious for most of you here but just to double check before I go under the car, is it safe to say that procedure 2 is my best bet? I know Tom's repaired drive shaft is longer and procedure 2 might not work for it.

Procedure 1 can't be done in 20 minutes. Go with Procedure 2, and don't try and beat the flat rate time, just go slowly and carefully.

fmugur, the second process is to inspect the shaft. It can be done with basic sockets and wrenches. A novice, diy'er should be able to get it out in an hour. You would not have to remove the case to do the inspection, but you will have to, to install one of my repaired shafts.

OK here is a question for you guys. Based on this thread it looks like if the front drive shaft is shot the the X needs to be towed. In a different thread I learned that you can release the front wheels by unplugging a connector (I assume a TC connector but I will look it up). Today I could have tried it since I took the drive shaft out to check the splines but this thought came to late in my mind. I will have to send my FDS to Tom for repair and I guess I can use the X while the drive shaft is being repaired. Any thoughts?

I wouldn't try it.

Do you have a 2004 onwards X5 with x-drive, or the earlier model without x-drive? The earlier one doesn't have that actuator and harness.

Here is the thread I was referring to.

No, mine is a 2000. Thanks JCL.

While traveling at a modest 55 MPH over a NY bridge, my 78,000 mile 2000 X5 suddendly felt like it shifted itself into Neutral without any warning. There MIGHT have been a momentary grinding noise but the engine over-reved at the same time. While waiting for a tow, I found the following:
Regardless of the gear the selector was in, the transmission acted as though it was in Neutral.
When the selector was in Park, it still "rolled" since I was on a slight upgrade.
I'm hesitant to bring it to the "stealership" since their typical diagnosis is "Replace the part" and in this case it could be the transfer case - my wallet is already beginning to hurt!
Any suggestions? Thanks...

It requires a physical diagnosis to confirm, but that sounds like the transfer case splines (output to front driveshaft). The dealer approach is likely to replace the transfer case. If you don't have a relationship there, try an independent garage that is familiar with BMW.

Look at posts #10 and #15 in this thread, and the subsequent discussion. There is a replacement spline offered by a poster in this thread, and several members have had good results with his work.

Thanks JCL but as I understand it, if there's a transfer case spline problem, there's still power to the rear wheels.
My problems seems to be unique since I've lost all power to both the front AND rear wheels. In addition to that, the car can still roll in Park. Do you still think it points to the transfer case?

Your transfer case doesn't lock together the front and rear driveshafts, like a part-time 4wd truck does. It is essentially an open differential. So yes, I think your problem still points to the transfer case.

Posts on here that mention still having rear wheel drive with a front driveshaft problem are referring to the 2004-onwards models with the x-drive transfer case, not the earlier models.
