With an assistant applying brakes, break free the staked collar nut at the center of the rear wheel hub without removing it completely. The wheel hub collar nut is tightened to a high torque, so ensure the car is firmly on the ground. Raise the rear of the car and remove the rear wheel, then remove exhaust components as needed. Remove the axle shaft mounting bolts from the differential flange and support the rear wheel bearing carrier with a suitable jack. Using the jack, lift the wheel bearing carrier so that the inboard side of the axle shaft clears the differential. Remove the staked collar nut and press the output shaft out of the wheel hub, then pull the axle shaft towards the center of the vehicle. For installation, follow the reverse of removal, using a new collar nut and applying a light coating of oil to the contact face of the collar nut before tightening it firmly, but not to final torque. Install the road wheel and lower the car to the ground, then with an assistant applying brakes, tighten the axle shaft collar nut to its final torque and stake the collar nut.
