I highly … Phasing is the process of aligning the universal joint yokes on both ends of the drive shaft (or double u-joint)in a parallel fashion. Safely raise the vehicle on an approved lift, and make sure it is secure. This condition is caused because every U-joint that operates at an angle creates a vibration. In such an exmple the engine could be horizontal, the drive sloping down at 5 degrees, and the pinion pointing up at 10 degrees. Alive.

Universal Joints by Bearing Type: Pin & Block (Plain Bearing) Friction-bearing universal joints for standard applications. Phasing affects torsional vibrations A drive shaft that is “in phase” and has the correct operating angles at the drive end of the shaft does not create a torsional vibration. It is interesting to note that an excessive torsion of the drive shaft can have negative effects on valve timing and lead to incorrect phasing. Phasing is the correct alignment between yokes at each end of the shaft. Found this during my first time routine maintenance (recently bought this thing). There is a video online that shows what happens when the alignment is not correct.

Ideally, the operating angles on each end of the driveshaft should be equal to or within 1 degree of each other, have a 3 degree maximum operating angle and have at least 1/2 of a degree continuous operating angle. As the output shaft of the transmission rotates it spins the driveshaft, which then turns the differential ring gear to rotate the wheels. The long drive shaft in my car had the slip yoke just forward of the carrier bearing 90 degrees out of phase. Our team can help you find the right gear for your application! Telescopic Drive Shafts.
