You can Select Your Vehicle to check if 22874937 fits your vehicle.

The drive axle-to-axle shaft flange bolts should be removed while having an assistant apply the brake to prevent the driveaxle from turning.

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

To remove and install components in the front differential for AWD systems, follow these steps: Remove the stabilizer bar link and, if applicable, the front shock absorber. Unbolt the right driveaxle from the axleshaft flange, supporting it properly. Support the differential carrier with a floor jack and a block of wood. Remove nuts attaching the axle shaft to its support bracket and the bolts securing the axle shaft flange to the differential carrier. Use a brass punch and hammer to separate the axle shaft from the differential case side gear. Remove the inner axle shaft assembly and axle shaft. Replace the inner seal and bearing with a special tool, then apply RTV sealant to the differential sealing surface and install the inner axle shaft housing assembly. Install the axle shaft to the support bracket and align the splines with the differential side gear. Tap the axle shaft with a mallet until the ring (clip) aligns with the groove in the differential case side gear. Install the axle shaft to the inner flange and tighten the bolts. Reinstall the stabilizer link, fill the differential with lubricant, install the differential carrier splash shield, and finally, install the wheel and lug nuts. Lower the vehicle, tighten the lug nuts, and check for proper operation.

To remove the semi-floating axle shaft, you need to remove the C-lock from the groove on the inner end of the axleshaft and withdraw the shaft, being careful not to damage the oil seal.

Power is transmitted through a pair of driveaxles equipped with sliding constant velocity (CV) joints capable of both angular and axial motion.

The optional locking limited-slip rear axle slows the rotation of the differential case when one wheel loses traction.

Before removing a semi-floating axle shaft, you should loosen the rear wheel lug nuts and raise the vehicle on jackstands.

Before removing the rear axle assembly, the following components need to be removed: driveshaft, shock absorbers, vent hose, brake hose, rear brake assemblies, parking brake cables, and rear wheel speed sensors.

To install the rear axle assembly, the reverse order of removal should be followed. All suspension and brake fasteners should be tightened to the torque value specifications.

Yes, there is an optional locking limited-slip rear axle available.

The initial steps to remove and install components in the front differential of selectable 4WD systems are as follows: Loosen the wheel lug nuts. Raise the vehicle securely on jackstands. Remove the right front wheel. Remove the differential carrier splash shield if equipped. Drain the lubricant from the front differential. For 4WD systems, unbolt the right driveaxle from the axleshaft flange and support it out of the way. Remove the front axle shift motor and, if applicable, disconnect the front stabilizer link or remove the front shock absorber/coil spring assembly. On 2500/3500 models, remove the front axle bracket bolts and slide the bracket forward for additional clearance. Support the differential carrier with a floor jack and a block of wood.

The initial steps are to loosen the wheel lug nuts, raise the front of the vehicle, and support it securely on jackstands.
