UNIVERSAL JOINT PHASING
When yokes are assembled to their shafts in the same plane, they are in phase. To obtain
vibration-free operation, check the following:
1.
The forward and second shafts, between the transmission and the intermediate axle,
must be assembled “In Phase”.
2.
The inter-axle drive shaft yokes, at the third shaft, must be assembled “In Phase”.
3. When drive shafts are running at parallel angles throughout the drive line system yokes
and flanges must be held parallel to within 1° of each other.
