Easy. Just need the right tools. The slide hammer axle bearing tool is necessary, for a proper and quick/easy repair. Be careful while doing the bearings as they can sling pieces very fast, safety glasses.

What type of axle? 1/2 ton? Just need to pull the diff cover off, remove center pin bolt, remove center pin, remove wheels and drums, push axle shafts in towards each other, remove c-clips, pull axles out, get a slide hammer with an axle bearing attachment, pull the old seal and bearing, get a bearing/seal driver set and install both. Then it's just the reverse. Don't even need to touch the brakes.

Make sure to check your axle shafts for wear as well. As well as I like to put a small film of rtv around these circular drivetrain seals, just some reassurance.

I made my own slide hammer attachment all you need is a piece of heavy strap cut it a little bigger than the bearing race then grind the ends 1/2 moon,drill a hole in the center. Put it on your slide hammer slip it in at an angle then pull it flat. it was easy. Another easy way is a long piece of conduit. Run it in from one side to the other use a hammer, use it like a long punch. That was a long time ago I may have had the diff out,don't remember. Sorry

Parts stores with rental tools should have all the stuff i mentioned. Or get creative as we all need to every now and then.

For the diff cover? I use rtv, permatex's the right stuff, but a high quality gasket should work like lube locker. I just don't mind cleaning off rtv. A die grinder and some of the abrasive rollock wheels do wonders, just have to be careful where the debris goes.

Unless you basically rebuild an axle and don't plan on pulling it apart a bunch then there's no need to take the cover on and off, where I would consider rtv superior.

Also to tag some one just type @ then their name as you see it@Mango It should pop up a little drop down box of members. Mine doesn't have a space.

Nope won't be able to tell until they're out. You have to look at the bearing surface, near the hub, and the splines.
