You can Select Your Vehicle to check if 19207872 fits your vehicle.

The inner ends of the driveaxles are splined to the differential side gears.

The differential allows the outer rear wheel to turn faster than the inner wheel when the vehicle goes around corners.

After disconnecting the driveshaft, it should be fastened out of the way with a piece of wire from the underbody.

After unbolting the brake hose retainer, the next step is to remove the steering knuckle and simultaneously pull the driveaxle stub shaft out of the hub.

Insert the pinion shaft, align the hole in the shaft with the lock bolt hole, and install the lock bolt.

Lower the vehicle and tighten the lug nuts.

Loosen the rear wheel lug nuts, raise the rear of the vehicle and support it securely on jackstands placed under the frame rails. Block the front wheels to keep the vehicle from rolling off the stands. Remove the rear wheels. Drain the rear axle lubricant. Disconnect the driveshaft from the rear axle pinion flange. Fasten the driveshaft out of the way with a piece of wire from the underbody. Position a jack under the rear axle differential housing, then raise it slightly. Disconnect the shock absorbers at their lower mounts, then lower the jack far enough so the leaf springs aren't compressed at all. Disconnect the vent hose from the fitting on the axle housing and fasten it out of the way. Disconnect the flexible brake hose from the junction block on the axle housing, then plug the hose to prevent fluid leakage. Remove the brake drums. Remove the bolts securing the parking brake cables to the rear leaf springs, then disconnect the parking brake cables from the parking brake mechanism at the brake shoes. With a jack under the differential for support, remove the leaf spring LI-bolts. With the help of an assistant, maneuver the rear axle over the leaf springs, rotate it to clear the springs, then remove the rear axle assembly from under the vehicle. Installation is the reverse of removal. Tighten the U-joint strap bolts to the specific torque. Tighten all suspension fasteners to the specific torque values. Tighten the brake fasteners to the specific torque. Bleed the brakes. Install the wheels and tighten the lug nuts to the specific torque.

To disengage the retaining ring on the inner end of the driveaxle from the differential or intermediate shaft, you should place the end of a brass drift against the inner driveaxle joint housing and apply enough force to disengage the ring.

The outer ends of the driveaxles are equipped with ball-and-cage type CV joints, which are capable of angular but not axial movement.

It functions like a conventional differential but with multi-disc clutch packs to equalize wheel rotation in low-traction situations.
