I am not familiar with the model but there is a limited number of methods most manufacturers choose to arrange such things. Mostly the necessary sliding is not in the differential but within the inner cv joint which is generally a plunge joint.
Think of the drive shaft as a single assembly that would usually be removed as such. Unless it is a type bolting to a flange at the diff - once the outer end has been freed from the hub the inner end must be removed from the diff housing. Rarely these can be withdrawn by hand and mostly they are retained by an internal snap ring or spring ring and must be levered out - suddenly.
The type bolting to a diff-mounted flange. Once the driveshaft has been unbolted the flange must be removed. Some have a central bolt or nut and some an internal snap ring and the same technique of creeping up and surprising it with a lever or hammer and drift is needed...
Open the bell. Take off the rear gear cover. U will loose all the fluid if any still in it so only remove some of the bolts loosen leave like 3 in around the bottom loosen them out a oil pan under the cover pry the cover off the diff leaving the 3 bolts to keep the cover from just popping off it will also help slow the rush of fluid. Once the fluid is drained remove the bolts and cover. On the inside u will se side gears. Have a helper push the axle shaft inward then u will see there is a C clip holding the axle carfully pry off the clip. Only do one side at a time. ... Then slide the shaft out where ur helper is. .. remove and replace the leaking seal. Then clean the axle. And u have to be easy sliding it in. Some times when the axle shaft is slide in u hit the end of the tube push the axle down toward the ground with variety of pressure as u push in this is tricky. But it will pop in. Then replace the clip and gentle have a helper try and pull back on the shaft. This sets the clip from falling out. Clean the bell area and scrap the old gasket off both sides if u have no replacement gasket get high heat black rtv silcone apply it to the cover or diff face and reverse the steps to install fill it with fluid and road test all this can be seen on youtube under inner axle seal repair. Good luck.

Worn side bearings is where the noise is coming from and might as well do both sides, I used replace them in about 2-4 hours, depending on where Murphy happened to be. Disconnect both side inner CV joint, front prop shaft and the 4X4 actuator line. If you want to drop the front pumpken. Not sure if you have enough room if you want to change the bearing without removing the pumpken from the frame. You should see when you disconnect the CV shaft.
The front diffs are toys compared to the rear, if you use auto4wd too much there are bearings in your tranfer case that are similar to the side bearings in the front diff. In both appearance and durability and soon you'll replace those too.
Good luck and keep me posted.

take off the housing cover in the middle of the rear end and to each side there is a retainer clip for each side. Pull it out and that side comes out. I don't think you needed to remove the rear end to do this though.

you have to undo the lower ball joint to swing the knuckle out of the way.
