U-Joint Phasing

When U-joint yokes are assembled to their shafts in the same plane, they are in phase. When they are assembled to the shafts in different planes, they are out of phase.

To obtain vibration-free operation, check and correct as necessary.

NOTE: On vehicles with a slip spline on the last coupling shaft, the yoke, which is part of the driveshaft slip yoke (4841), should be considered part of the coupling shaft.

Mark splined driveline components prior to disassembly to ensure that they have the same relative orientation when reassembled.
