Section 05-02F: Differential, Dana Model 80 Locking Axle | 1996 F-350 Super Duty Workshop Manual |
No adjustments or alterations should be made to the Detroit Locker® differential (4026). Refer to the appropriate Group 05 section for adjustments to other components in the axle.
When making brake adjustments, the wheels on both sides of the vehicle must be raised and the transmission (7003) placed in neutral so that the ring gear and opposite wheels are free to rotate with the wheels on the side being adjusted.
Backlash cannot be adjusted. A certain amount of backlash is necessary for disengagement and reverse operation, but this is set and cannot be changed.
