    "SDT ="     C × (B + A)        
B    "SDT" is the actual seal drag torque in newton meters (N m)."C" is the torque wrench reading in newton meters (N m)."B" is the length of the torque wrench in meters."A" is the bolt circle radius of axle housing assembly (2) in meters. This is equal to 0.229 m (9.016 inch).
Tighten nut (11) by using one of the following methods:
Rotate the axle housing assembly. Use Tooling (E) in order to tighten bearing nut (11). Install Tooling (H) on the axle housing. Place a torque wrench on the bolt at the center of Tooling (H). The torque wrench reading is equal to the seal drag torque plus the axle bearing preload rolling torque. Use the seal drag torque that was recorded in Step 10.Note: The preload rolling torque for new bearings is 9 to 16 N m (7 to 12 lb ft). The preload rolling torque for used bearings is 4.5 to 8 N m (3.5 to 6 lb ft).
Use the torque wrench in order to rotate the axle housing assembly. Use Tooling (E) in order to tighten nut (11). The torque wrench reading must equal the axle bearing preload rolling torque plus the actual seal drag torque. Use the seal drag torque that was recorded in Step 10. Use the following formula to calculate the required torque wrench reading. This formula is used to measure torque at the bolt circle.

    "C ="     B × (T + SDT)        
B + A    "C" is the torque wrench reading in newton meters (N m)."B" is the length of the torque wrench in meters."A" is the bolt circle radius of axle housing assembly (2) in meters. This equals 0.229 m (9.0160 inch)."SDT" is the actual seal drag torque in newton meters (N m)."T" is the axle bearing preload rolling torque. The preload rolling torque for new bearings is 9 to 16 N m (7 to 12 lb ft). The preload rolling torque for used bearings is 4.5 to 8 N m (3.5 to 6 lb ft).
The axle shaft should have zero end play. If the axle bearing preload rolling torque exceeds the specification, back off bearing nut (11) by 1/8 turn and reseat bearing cone (12) against bearing nut (11). Perform Step 11 again.
