WTF?? Guibo replacement

[HardTech]

How is this going to work?

The rear of the driveshaft is bolted via studs, even if you could move the driveshaft off the studs, it can't go anywhere because its encased by the subframe.

To remove with dampener
Drop the exhaust off the rear hangers and remove the tunnel cover. Unscrew the clamp ring just behind the CSB, loosen the CSB bolts and pry the front section back as far as it will go. Now remove the CSB bolts and drop the driveshaft down in the center. With a little bit of a fight it will come off 3 studs. You need to turn the driveshaft abit to get the flex disk to clear the studs. Bentely manual says 60*, but I never understood that.

Now to prevent the problem in the future, remove the rear tail flange as described in Kenikas guide. (Nice work by the way) Now with the flange removed, knock out the 3 studs and remove dampener. Throw dampener and studs into nearest trash can. Replace the bolts with 10x1.5x50 and new metal lock pinch nuts.

I checked the CSB for anything that can be unscrewed/unbolted/undone... except for the two bolts that attach it to the chassis, I didn't see anything. When you say pry the front section back, what part do you mean?

From your post, it sounds like I have to remove the CSB before being able to drop the driveshaft. I guess this is where I'm having problems. I tried to drop the driveshaft, but there was something that prevented it from fully dropping. Maybe it was the CSB.

Its a two peice drive shaft. If you look on the back side of the CSB you will see a collar nut. You will notice you have about 2 inches of splines showing.

If you loosen the collar nut and the 2 attaching bolts for the CSB, you can push the front half of driveshaft backwards about 2"'. Now remove the 2 CSB bolts and drop the center of the shaft down, you should be able to twist and clear the 3 studs snd drum.

How come you replaced the guibo? I'm curious if mine needs replacing. I know somethings isn't right but I need to diagnose what it is.

Guibo or flex disc is a wear item, and chances are your PO didn't replace it.

Thanks Jean, as always you're quite helpful and informative.

thanks for your help, man.. I appreciate it. However, I loosened the collar nut and pushed down on the center, but still no go. The driveshaft is still attached to the guibo. I can't get the bolts off. I can remove the 3 nuts holding the guibo to the transmission, but I can't get the driveshaft bolts off unless I can get behind it
