Fill the Axle with Lubricant NOTE: For additional lubrication information, See the Maintenance Manual 1, Lubrication. To obtain this publication, See the Service Notes page on the front inside cover of this manual. 1. Park the vehicle on a level surface. When the angle of the drive pinion changes, the lubricant capacity of the axle will change. 2. Remove the fill plug from the side of the bowl cover of the axle housing. Figure 5.112.

Fill the axle with lubricant until the lubricant level is to the bottom of the fill plug hole. See the Section 7. 4.Install the fill plug. Tighten the fill plug to 35 lbft (47 Nm). When correctly installed, one complete thread of the fill plug is visible between the housing and plug head. 5. Road test the vehicle in an unloaded condition for one to two miles (1.6-3.2 km) at speeds not more than 25 mph (40 kmh). Recheck the lubricant levels and all the fasteners. 6. If used, inspect the operation of the driver-controlled main differential lock. See the Section 6. 85
Driver-Controlled Main Differential Lock Hazard Alert Messages Read and observe all Warning and Caution hazard alert messages in this publication. They provide information that can help prevent serious personal injury, damage to components, or both. WARNING To prevent serious eye injury, always wear safe eye protection when you perform vehicle maintenance or service. Description Some Meritor drive axle models have a drivercontrolled main differential lock (DCDL). This differential lock is operated by a differential mounted, air actuated shift unit. When activated, the shift unit moves a sliding collar which is installed on the splines of the axle shaft. When engaged, the collar locks the axle shaft to a second set of splines on the differential case. Both driven wheels are then simultaneously engaged. Figure 6.1. SENSOR Figure 6.1 SPRING PISTON SHIFT SHAFT O-RING SHIFT COLLAR SHIFT PORK CYLINDER CAPSCREW MANU- AL ENGAGING NOTE: Meritor differential models with driver-controlled differential lock equipment are manufactured in metric dimensions and sizes. When these differential are serviced, it is important to use the correct metric size tools on the fasteners. See the Section 8. Removal Differential Differential from the Axle Housing Before the differential can be removed or installed, the differential lock must be shifted into and held in the locked or engaged position. The locked position gives enough clearance between the shift collar and the axle housing to permit the removal or installation of the differential. NOTE: If the axle shafts were removed for or towing with the differential in the unlocked or disengaged position, Install the left hand axle shaft into the housing before continuing. Perform the following steps for reinstalling the axle shafts into the axle housing. 1. Remove the protective covers, if used, from the wheel hubs. 2. If the drive axles are equipped with a main differential lock, shift the differential to the unlocked or disengaged position. Install the axle shafts with two sets of splines and new gaskets in the correct location as follows. Figure 5.109. A. Push the axle shaft and gasket into the hub and housing until the shaft stops against the differential lock collar. B. Push down and in on the axle shaft flange and rotate the shaft until the splines of the shaft and the shift collar are engaged. C. Push the axle shaft further into the housing until the shaft stops against the differential side gear. D. Push down on the axle shaft flange and rotate the shaft until the splines of the shaft and the side gear are engaged. E. Push the axle shaft completely into the housing until the axle shaft flange and gasket are flush against the wheel hub. 86 MAINTENANCE MANUAL
