Q: How to install the rear differential carrier assembly with differential lock on Toyota 4Runner?
A: The first step for installing the rear differential carrier assembly with differential lock requires cleaning both the differential carrier assembly and axle housing contact surfaces and removing any present dust and oil. First apply a new gasket before installing the differential carrier assembly and 11 washers with the 11 nuts and torque them to 25 Nm (255 kgf-cm, 18 ft-lbf). After installing the wire harness with its accompanying 2 nuts at 23 Nm torque (235 kgf-cm; 17 ft-lbf), one should connect the breather tube before finishing with the connector of the 2 actuators. The correct procedure should be used to install the rear axle shaft LH before repeating the same process for the rear axle shaft RH. Mount the rear propeller shaft according to necessary methods which cover both 2WD and 4WD configurations. Complete the task by adding differential oil then check for the proper condition of the differential oil when necessary.
Q: How to remove and replace the rear differential carrier assembly with a differential lock on Toyota Tacoma?
A: The process to change the rear differential carrier assembly with differential lock starts by disconnecting the negative battery cable followed by removing the rear wheel and draining brake fluid. The braking process starts by extracting the rear brake drum sub-assembly and then proceeding to remove the front and rear brake shoes. Drivers who possess 2WD drive systems need to eliminate either the regular cab propeller shaft or the propeller with center bearing shaft for models different from regular cab. The 4WD on each cabinet must undergo identical steps to specific cab arrangements. Start by drain the differential oil and proceed to disconnect the rear speed sensors on both left and right sides while applying the same method to the right side as for the left side. For cable assembly separation of No.3 then No.2 parking brake use the right side procedure which mirrors left side commands. The rear axle shaft must be detached with backing plate from both sides before finalizing the removal of the rear differential carrier assembly through connection disconnection of differential lock actuator and breather hose followed by differential carrier assembly nut removal. Caution should be applied to prevent damage of the contact surfaces on the differential carrier and rear axle housing before extracting the rear differential carrier gasket from the assembly.
Q: How to remove and replace the differential carrier assembly on Toyota Tundra?
A: You must remove the rear wheel before starting to work on the differential carrier assembly of 1GR-FE and 2UZ-FE. The initial step requires removal of the propeller shaft assembly. The next phase concerns 2WD drive/propeller shaft removal while 4WD systems require their respective procedures. After differentials oil removal drain the vehicle user must uninstall the rear axle shaft LH by performing similar installations as for the rear axle shaft RH. The rear differential carrier assembly needs removal after discarding its 10 nuts and 10 washers with the differential carrier until both the differential carrier and rear axle housing contact surfaces remain undamaged while also removing the gasket.
