Installation

Except F-Super Duty, Commercial Stripped Chassis and Motor Chassis

1. Lubricate the coupling shaft front slip yoke splines with Long-Life Lubricant, C1AZ-19590- BA (ESA-M1C75-B) or equivalent. Remove the tool preventing leakage from the transmission housing. Install the front yoke of the coupling shaft assembly on the transmission output shaft. Do not allow the slip yoke assembly to bottom on the output shaft with excessive force.

2. Secure the center bearing support bracket to the frame crossmember with the center support attaching bolts. Tighten the bolts to specifications.

3. Apply a coating of Long-Life Lubricant C1AZ-19590-BA (ESA-M1C75-B) or equivalent to entire splined stub shaft end of the coupling shaft assembly prior to the assembling of the driveshaft and the slip yoke.

4. Using a clean long handle (stencil type) brush apply Long-Life Lubricant C1AZ-19590-BA (ESA-M1C75-B) or equivalent, spread evenly on all the female splines of the slip yoke.

5. Assemble the driveshaft slip yoke to the coupling shaft.

6. Connect the rear U-joint of the driveshaft to the rear axle companion flange and tighten the U-bolt nuts to specification.

7. Using a hand type grease gun, lubricate the driveshaft slip yoke through the zerk fitting with Long-Life Lubricant C1AZ-19590-BA (ESA-M1C75-B) or equivalent.

NOTE: To assure complete lubrication of the slip yoke splines, temporarily plug the vent hole in the "welch" type plug located at the yoke-end of the slip yoke while applying grease through the zerk fitting.
