Caution | Risk of injury caused by scraping or cutting body parts on sharp vehicle parts | Always wear protective gloves when working on or near sharp and non-deburred vehicle parts. | |
1 | Support the base of the dial indicator bracket (11) with the dial indicator (10) on the flat surface of the differential assembly housing (1) | The dial indicator (10) must be in a vertical position with its probe resting on the flank of one of the toothed crown teeth, with a preload of approximately 2 mm. | |

2 | Turn the differential assembly a few times and measure the gap between the teeth of the toothed crown and the pinion in at least three different points displaced by 120 ° | In the measurement, determine the lowest play point between the measured points | |
Differential ring gear teethplay | |||
3 | Lock the pinion at the point of least play and move the differential assembly in the axial direction acting on the threaded rings until to get the greatest prescribed clearance | The value above the greatest specified clearance will be necessary to adjust the preload of bearings (4). | |
4 | Loosen the threaded rings to relieve the load on the tapered roller bearings (4), then press them again | Press the threaded rings lightly to avoid load on the bearings. | |

5 | Determine the differential set mounting measure | ||
6 | Adjust the pre-load of the tapered roller bearings (4) | ||
7 | Tighten bearing cap bolts (9) to the specified tightening torque (2nd step) | If not already fitted. | |

8 | Install the safety locks (5) and tighten the screws (6) of the threaded rings (2) | Safety locking bolt to the bearing cover | |
| Check | ||
9 | Turn the differential assembly a few times and recheck the gap between the flanks of the toothed crown and the pinion | If the nominal value has not been reached repeat the instructions from the step 2. | |
10 | Check the contact marks between the toothed crown and the pinion | ||
