Pinion Gear: Testing and Inspection
Drive Pinion Preload Check and Final Depth Check
1. Install the drive pinion into the carrier housing.
2. Install a new collapsible spacer.
CAUTION: Never reuse a collapsible spacer. Upon removal, always discard the old spacer and install the new spacer for assembly.
3. Assemble the outer pinion bearing cone and roller and thrust washer.
4. Coat the pinion seal with Motorcraft Synthetic Rear Axle Lubricant F1TZ-19580-A meeting Ford specification WSL-M2C192-A. Install the seal
with Pinion Seal Replacer T79P-4676-A.
NOTE: After installation, make sure the garter spring did not pop off. If the garter spring pops off, remove and replace the seal.
5. Install the rear axle companion flange with Companion Flange Replacer T85T-4851-AH. Install the companion flange washer and nut and tighten
the companion flange nut to 271 Nm (200 ft. lbs.). Check torque required to rotate pinion 1.7-2.8 Nm (15-25 inch lbs.). If required torque is not
to specifications, continue to tighten companion flange nut in small increments until proper torque is obtained.
6. If the reading is more than 1.7-2.8 Nm (15-25 inch lbs.), the collapsible spacer must be replaced.
CAUTION: Never tighten the pinion nut more than 475 Nm (350 ft. lbs.), or the collapsible spacer will be compressed too far.
