Installation Note

Verify that the splines on the pinion stem are free of burrs. If burrs are evident, remove them with a fine crocus cloth. Work in a rotating motion to wipe the pinion clean.
Lubricate the pinion flange splines.

CAUTION:
- Never use a metal hammer on the pinion flange or install the flange with power tools. If necessary, use a plastic hammer to tap on a tight fitting flange.
Align the index marks and install the pinion flange.

CAUTION:
- Do not loosen the nut to reduce preload. Install a new collapsible spacer and nut if preload reduction is necessary.
Use the pinion flange holding tool SST to hold the pinion flange while tightening the nut to set the preload.
1. Tighten the nut, rotating the pinion occasionally to ensure the differential pinion bearings are seating correctly. Take frequent differential pinion bearing preload readings by rotating the pinion with a Nm (inch-pound) torque wrench. The final reading must be 0.56 Nm (5 lb-in) more than the initial reading taken during step 4 removal.
