I received my driveshaft today :)
Ya,...I know...it's no MMC, but hey what other option did I have. It's a DynoTech 3.5" made out of 6061 aluminum. I will be installing it in just a few days and have some questions about the process.

1)Yoke and flange connection bolts-What did you guys torque these down to?

2)The real question-I noticed there are several combinations to connect the DS yoke and flange(the flange is rotated in every pic if you didn't notice). Since I will not be using the old parts what is the correct way to bolt them together? Does it matter since they're both new(diff/shaft)?

RE: Driveshaft has arrived

From the manual...

Rear Flange Bolts ~ 71-95 Lb-Ft

Being new it shouldn't matter in the timing of the driveshaft flange to the pinion flange. IF you detect a vibration, simply perform the driveshaft indexing procedure...

Driveshaft Indexing Procedure

The first check to be performed when driveshaft vibration is suspected is re-indexing the driveshaft at both the rear axle and transmission.

A vibration free driveline can result from the driveshaft indexing procedure when minor driveshaft imbalance is cancelled by minor system runouts.

1. Raise vehicle on hoist. Refer to «Section 00-02». Remove rear wheel and tire assemblies and rear rotor assemblies. Place floor stands under suspension arms to support rear of vehicle. Note or mark indexing of driveshaft to transmission and axle companion flange.

2. Mark one hole position on driveshaft yoke at rear of driveshaft with the letter A and the eight circular flange holes (starting with the mating hole with driveshaft position A) from one through eight. Position A-1 is considered the original index position.

3. Disconnect driveshaft, re-index 180 degrees at axle position A-5. Check for vibration at road test speed. If vibration is still present, evaluate positions A-3 and A-7.

4. If further improvement is desired, evaluate remaining positions that are located between the best of the two previous positions, A-3 and A-7. If vehicle tests satisfactorily at any point during this procedure, do not proceed with any further steps.

NOTE:
Check universal joints for binding during first re-indexing.

5. If re-indexing at axle is unsuccessful, disconnect the driveshaft , re-index 180 degrees at transmission only and connect. Check for vibration at road test speed. If vehicle tests satisfactorily, do not proceed with any further steps.

NOTE:
Remove driveshaft from vehicle and manipulate universal joints in each direction of rotation. If a universal joint feels stiff or has a "lumpy", "gritty" feel in any direction, replace universal joints.

6. If re-indexing at both axle and transmission is unsuccessful, refer to «Driveshaft Balance Diagnosis» as outlined.

NOTE:
Original equipment driveshaft-to-axle companion flange retaining bolts (N-800594-S100) are Loctite coated and do not require a lockwasher. If these bolts are removed, they may be installed, if additional Loctite is applied. New and used bolts must be tightened to 95-129 N-m (70-95 lb-ft).
