Motor oil should be fine, but if it doesnt go on smoothly, you have other more seriousissues. If the tailshaft is twisted, no amount of oil will make it smooth, and you have a useless OD output shaft.

Yes the yoke moves on the tailshaft as the rear suspension goes up and down andalters the drive shafts geometry. Once again, smooth opperation in important.

No. Get a new tailshaft to start. The problem is more serious than worrying about shredding the oil seal, you will break the end of the case where the drive yoke bushes are installed if there is any noticable misalighnment of the tailshaft, or if the tailshaft is bent.

Yes, the tail shaft on the OD tranny is the smallest diameter part on the driveline, and spirited driving "dumping the clutch" in first or second generates over 300 lb ft of torque static, and over 1500 lb ft of torque dynamic. Owners of OD equiped cars generally know not to dump the clutch. The tailshaft can bend if the tranny was dropped "litteraly" while the tranny is being lowered from the car "still attached to the motor".

Good luck.
