Just ran into this today after starting a routine brake pad replacement. Through a lot of trial and error I've found that the axle is easy to remove but the bearing and bearing retaining ring are quite a job to remove so you can get the seal off. Then you have to get a new bearing and retaining ring pressed on the axle.
What I learned:
*Don't start the job on a holiday weekend.
*You do not need to remove the rear diff cover but use a floor jack to raise the axle end you are working on to prevent fluid from pouring out.
*get all the parts before you start (retainer, bearing and seal)
I'll add for anyone who doesn't know, Permatex makes a gear oil RTV that works fantastic in applications where gear oil is involved. I plan to get lube locker permanent gaskets for my diff covers, but I figured I'd mention it in case folks didn't know.
