You can Select Your Vehicle to check if 25931936 fits your vehicle.

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.

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.

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.

To check for wear in the CV joints and driveaxle shafts, grasp each axle and rotate it in both directions while holding the CV joint housings, feeling for play indicating worn splines or sloppy CV joints.

After raising the vehicle and securing it on jackstands, you should pry off the hub cover and remove the driveaxle/hub nut while bracing the hub to prevent it from rotating.

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.

The next step is to drain the differential lubricant and remove the differential cover.

For leaf spring models, the spring U-bolts should be disconnected, followed by removing the springplates. Then, the jack can be lowered under the differential to remove the rear axle assembly.

When diagnosing axle problems, it is important to check for other possible causes such as road or tire noise, and to isolate engine and transmission noises.

If the vehicle has a differential carrier splash shield, it should be removed after removing the driveaxle/hub nut.

The next step is to drain the differential lubricant and remove the differential cover.

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

The inner end of the driveaxle should be lowered and pulled out of the hub, carefully guiding the driveaxle out from under the vehicle.

To install the semi-floating axle shaft, you should insert the axleshaft into the housing until it engages with the differential side gear, install the C-lock, and insert the pinion shaft. Then, install the cover, fill the differential with lubricant, and install the brake disc or drum.

To remove and install components in the front differential for 4WD systems, follow these steps: Remove the bolts securing the axle tube to the differential carrier and the nuts attaching the tube to its support bracket. Carefully remove the output shaft tube, ensuring no components fall out. Mount the tube in a vise and remove the internal components. Measure and remove the axleshaft bearing using a slide hammer and bearing remover attachment. For installation, install the bearing to the original depth using a bearing driver or socket, then install a new seal and deflector, lubricating the seal lips with grease. Carefully drive in the axleshaft, followed by the internal components. Apply RTV sealant to the tube-to-differential housing mating surface, and install the tube assembly, tightening bolts and nuts to specified torques. Reinstall the driveaxle, front axle shift motor, and fill the differential with lubricant.

After installing the rear axle assembly, the brakes should be bled, the wheels and lug nuts should be installed, and the vehicle should be lowered. Finally, the lug nuts should be tightened to the proper torque specification.

If a boot is damaged, the CV joint can be disassembled and cleaned, but if any parts are damaged, the entire driveaxle assembly must be replaced as a unit.

No, overhauling the differential requires special tools and is not cost-effective for a do-it-yourselfer.

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

For coil spring models, the links for the electronic suspension control sensors should be detached, followed by detaching the track bar from the rear axle. The stabilizer bar, coil springs, and upper and lower trailing arms should be disconnected from the axle assembly. Finally, the jack can be lowered under the differential to remove the rear axle assembly.
