System balanced drive axles utilize a deflector design on the pinion flange, that is able to hold system balance weights on its outside diameter.
Important: The dial indicator will display inverted readings. You are measuring the inside diameter of the flange, not the outside diameter. The highest reading on the dial indicator is the low spot; the lowest reading is the high spot.
Important: All runout measurement tolerances provided are to be used as guidelines. The measurement tolerances provided and their effect on vibration correction may vary for each vehicle.
If the drive axle utilizes a crush-type sleeve to achieve pinion bearing preload, the pinion flange can only be removed and installed 1 time before the crush-type sleeve must be replaced. Sleeve replacement requires removal and installation of the ring and pinion gear set. If there is evidence that the pinion has been removed and installed previously, replace the sleeve.
Important: Inspect the runout of any replacement pinion flange.
Important: If the pinion flange was reindexed or replaced, the driveline MUST be system balanced.
