How to disassemble the differential carrier assembly on Chevrolet Trailblazer?

In order to disassemble the Differential carrier assembly, first remove the drain from the axle and drain the axle lubricant, check the oil and case for metal chips to identify where the problems are. Use an inch-pound torque wrench to measure the rotating torque of the pinion and Differential case. Start the disassembly process by installing the j 29369-1/ j 02619-1/ to the inboard side seal and remove the seal by pulling the j 02619-1. Repeating the same process for the outboard side seal using the j 29369-2 and ja 02619-1. Then unbolt the half for the Differential carrier and take the halves off to get to the Differential case assembly. Remove the left side Differential bearing adjuster using the tool j 42213 (Adjuster Sleeve Socket) labeling it, followed by the removal of the left side Differential bearing cup. Do the same for the right side with j 45224 (Side Bearing Adjustment Wrench) to unbolt the right side of the Differential bearing adjuster and cup. Take the rotating torque of the drive pinion and note it down. Attach the j 8614-01 (Flange and Pulley Holding Tool) unto the pinion yoke and unfasten the pinion nut while gripping it. Remove the pinion yoke, washer, and the drive pinion using the j 45234, (Pinion Remover). Carefully remove the dust deflator from the pinion yoke and pinion oil seal along with the outer Pinion Bearing incident to the removal. First, install the j 22912-01 (Split-Plate Bearing Puller) between the Pinion Bearing and pinion gear and remove the inner Pinion Bearing using the j 22912-01 and h bundle hydraulic press. Take out the pinion gear selectable shim and install the j 45228-4 (Pinion Bearing Cup Remover/Installer) to the Pinion Bearing cup. Remove the outer Pinion Bearing cup with the help of the j 45228-1 and j 45228-5 by turning the latter clockwise. Lastly install the j 45228-4 on the inner Pinion Bearing cup and with the help of j 45228-1 and j 45228-5 to remove the outer Pinion Bearing cup rotating the j45228-5 clockwise.
