Overhauling the differential is not typically a cost-effective endeavor for a do-it-yourselfer. Instead, any further work involving the differential should be entrusted to a qualified repair shop with the appropriate expertise and equipment.

To separate the drive axle from the axleshaft flange, you need to connect a floor jack under the outer end of the lower control arm and raise it slightly. This helps with maneuvering the drive axle. Then, disconnect the tie-rod end from the steering knuckle.

After raising and securing the vehicle, remove the rear wheels. Position a jack under the rear axle differential housing. Proceed to disconnect the driveshaft from the rear axle pinion flange. Disconnect the shock absorbers at their lower mounts. Also, disconnect the vent hose from the fitting on the axle housing and secure it out of the way. Unbolt the brake line fittings from the brake hose junction block, and then remove the brake hose junction block from the axle housing, plugging the hose to prevent fluid leakage. Don't forget to disconnect the ABS wheel speed sensor electrical connector(s).

Prior to guiding the axleshaft back into the axle housing, apply a thin coat of grease to the outer surface of the bearing. If you're working on a four-cylinder, 2WD Frontier, or Xterra model, make sure to install any shims that were present during removal.

Often, problems suspected to be related to the axle may actually stem from other causes. Therefore, it's crucial to perform a comprehensive examination of potential contributing factors before assuming that the axle is the root of the issue.
