I would never do my own. That **** smells so freaking bad. Forget about it if you get some on your hands. yuk

 

I just got done changing my diff fluid. Wasn't hard to do, and it was well worth the money. There are a few tips I have for others. First, the filler plug is 23mm, and the drain plug is 24mm (don't know why they made them different.) Second, ALWAYS buy new gaskets, for oil changes too, it's worth the $1 you'll spend not to have little spots all over your driveway. Lastly, invest in a good torque wrench. It'll assure no leaks, and avoid those annoying tightass bolts later down the line. Remember, tighter isn't always better.

 

I am getting mine changed out while it is gettin fixed and PFC instaled.
