Torque Tube bushing swap
Well, I finally swapped the bushing in the torque tube for a piece of mind. I only did this becuase I am swapping the MM6/4.10 for M12/3.42. With the HP I'm putting down, 4.10's were too much. After the test drive, IMHO this is the best combo (Z06 have this set up). I did the job at a friend's house with a lift. It took us about 6 hours taking out time from start to finish.
I want to thank Fartpipe (Bruce) and Tony (ajg1915) for helping me with the TT stuff.
All my parts in the car.
Trannie and rear
Cradle is out.
Then the TT/trans/rear.
TT is seperated from trans.
Pics with old bushing (not bad, better than I thought).
New front bushing (this is BMW part) and new billet rear bushing.

Tony is correct. I did mine becuase it was good insurance while I was in there. And as suspected the bushings were cracked. I replaced my front one with the BMW part and the rear with a billet piece. If you do any type of racing I would strongly advise doing this. Also, the bushings do come apart with age. Do a search, there was a thread where the bushing actually came apart and caused driveline vibrations.

We are pulling the driveline tonight so I will do an inspection then. The car is an 02 with 23k miles on it. I do use it for HPDE / track days!
Is there a particular reason to do rubber up front and billet in rear? vs all rubber or all billet?

I just put an LS7 clutch/flywheel in my '02 a couple of weeks ago. Took the propeller/drive shaft out of the torque tube to inspect it. Everything looked almost new in there so I didn't bother replacing the couplers at that time.
I do have a question however, how did you remove the bolts that hold the couplers? Didn't appear to be a whole lot of room to work with the bolts and according to the shop manuals, if I remember correctly, the bolts are held in with some lock-tite or threadlock.

Make sure you mark where the couplers are joined and these pieces are balanced just like a clutch and if you screw it up you might get some vibrations.
Also there are arrows on the couplers as to which way the are suppose to go on the sides of the rubber disc couplers.

Use a wire brush and clean the threads up real nice before applying loctite and retorqueing.
