To remove a full-floating axle shaft, you need to remove the bolts attaching the flange to the hub and withdraw the shaft from the housing.

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

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.

The outer ends of the driveaxles have a stub shaft that is splined to the front hub and bearing assembly and locked in place with a large nut.

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.
