Ah, the wrong bolts are too short for you to get nuts on...that's one thing...didn't think that flange was threaded, but it still takes nuts on mine...check realoem for your car and make sure you get that part right.
Hmmm, didn't even notice that. I haven't done any work on the drive shaft at all, bought the car with 107,000 miles on it. don't know what the PO had done, but from what I can tell, not much.

You are right, see below. Appears I have two issues, 1-the wrong bolts on three of them and 2- not nuts on three of them. Weird!

Just make sure you're looking at your car's setup. That might be correct for an Xi, but I wonder.

Yeah its for my car. Do you think I can just take out the incorrect ones and put in the correct ones, one at a time?

Hold on.

Those photos are of the guibo on the FRONT driveshaft, correct?

If yes, everything is assembled correctly.

yes, but what is installed on my car doesn't match what realoem.com shows for the car. Hmph!

WAIT! Now I'm really confused. The picture below shows yet ANOTHER GUIBO on my car, for the front shaft - which is apparently the one I thought was the guibo and the one i took a picture of above!? See #2 below. Realoem.com doesn't even give "further intervention" for this part. What gives, thought there was only that main one.

I don't know. See below. Both of these are for my car from realoem.com. The first is titled "Drive Shaft, 4 wheel", the second is titled "Drive Shaft, Single Components, 4 wheel". Both are for E46 330XI. They show different bolts to connect the "guibo" to the TC. And, according to ECS website, the part number 1 in the second picture below is called the "guibo",
Universal Flex Disc
Also known as a "Giubo"
Brand: ES#:48442 Mfg#: 26111229360

But, what I took a picture of above is NOT that part, its the one shown in the first picture below which uses the torx screw connector, not the bolt #6 shown in the second picture. AND, bolt #6 in picture one is the same as bolt #3 in picture two - same part number. Bolt #4 in picture one (the torx one - as shown in my picture above) isn't even listed or shown in picture two.

Not jumping on a band wagon. The csb may very well be fine. However the symptoms described match a probable cause, which from personal experience was found to be bad on my vehicle. Just as other responders personal experience point to transfer case bushings, cv joints, guidos, etc. Heck a torn air inlet boot has been claimed to have cause almost every reported problem on this forum and sometime it is. The op was looking for probable causes for a problem he was experiencing that's why he's on the forum. A thump thump thump under the arm rest would led one to investigated the center of the car after checking for a torn air boot first of coarse. While poking around one might as well check the other likely suspects TC bushing, Drive shafts, CV Joints, Guido, and yes even the Center Support Bearing. Expanding the search one should look at flat tires, not round wheels, out of balance wheels, CABS, ball joints, tie rod ends, frame bushings, rear CV joints and axles, wheel bearings etc etc etc. All cause vibration and thumps when bad. If you are under the car and in the area inspect them. My guess base on the reported symptoms and the things the OP ruled out still leaves me to believe that CSB which has not yet been examined may be the cause. I don't have to be right, I just hope it helps. Since the Op is already going to replace the TC Bushing he might as well check out the CSB while he is under the car. At least he can rule it out.

^ Will you shut up with the CSB?

You already mentioned it twice. It's nice you replaced it on your car. Two days ago you were asking around for a replacement TC because you are still having issues, and now you are the expert while everyone but you is an a@@hole?

BTW- It takes 2 minutes to check intake boots or a TC bushing. I'd like to see you check a CSB in two minutes.

Nobody is running out to replace a part that doesn't fail frequently before inspecting a few failure prone parts. That wouldn't make sense.

Any clarification from those that have actually looked at or replaced their guibo or csb?

I replaced both on my 02 XI. What's your exact question?
If your asking about the multiple bolts.. go with 26117523709 quantity of 6
also order 07129900047 quantity of 6.

Those are the the bolts and nuts you need to fasten your guibo to the TC. That's exactly what I used less than a year ago when doing mine.

I even have a guibo + bolts for sale if your interested.

No worries figured I offer. The reason I got this stuff was exactly because of the "monkey see-monkey do".

Once I got to my guibo and CSB I realized my guibo was fine but I swapped it out anyways. Also the bolts are reusable so if you had the right ones you'd only need the self locking nuts.

Ignore that diagram that shows the 3 bolts.. The diagram for my 02 XI is exactly the same yet I ordered the 6 bolts like I said above and everything installed without issues.

Sorry to All. Bad week at work I guess. Didn't mean to be a a@@hole.

No, I'm confused why you are confused.

Xi's built after 3/03 with a manual tranny have a front guibo in a addition to the rear guibo that all xi's have. If you have it, the front guibo should look and be bolted up to the driveshaft/front diff just like you show in the photos. The rear guibo uses the six nut/bolts. The front uses three torx and 3 nut/bolts.

*Use loctite when you re-install the torx style bolts!

Realoem doesn't have a part number for the front guibo since its "part of" the driveshaft.

I'm sure there's a part number for just the guibo if you want to look- doesn't matter since yours is fine.

Keep looking into the TC mount. Support the tranny and remove the bolt through the center of the mount- I bet the metal core of the mount isn't even connected to the rubber of the mount and falls right out.

I had a similar problem with vibration at a certain RPM that only got worse with time. Turned out to the the driveshaft CV joint.
