Remove skid plate ~45 seconds
Remove drain plug ~30 seconds
Reinstall drain plug ~30 seconds
Fill diff ~5-10 minutes
Install fill plug ~30 seconds
Reinstall skid plate ~60 seconds

Whole process not including jacking up the front of the truck might take 10-15 minutes depending on how fast you can pump the fluid back in. Very easy, absolutely no point in bringing it to a shop.

The front diff oil will prolly' look terrible if you have never drained it before... so dont freak out.

Expect a fairly metallic look...

You might want to fill it with some cheap gear oil.... go for a quick spin.. and come back and dump it again before refilling it with the good stuff.

I bought my LLY with 50k miles on it... front diff oil looked like aluminum paint!!

After flushing it out, its been good ever since.

Any local auto parts store.

See those little tubes? You can adjust the pump suction depth to fit different bottles.

The way I do it is to dump 4 quarts of gear oil into a old windshield wiper fluid bottle.

Its way easier than switching from quart to quart to quart... cleaner too.

One of those little adapter tubes will fit the washer fluid bottle perfectly and the pump portion should screw right on.

Easy....
