Changing rear differential cover.

Want to change mine out to something better for look and abuse.
I assume when changing these out, its new fluid, seals etc? This is not just a cover or a closed case, correct?

My dealership recommended a differential fluid service on my next visit. Is this the time to allow them to install?
Is this something that an avg joe can do?

You can do it at home. You need a cover, proper lube and RTV sealant or Lube locker gasket.

Remove the old cover.
Clean off the axle housing
Put gasket or RTv on the cover and install
Refill immediately if you used the lube locker or wait for RTV to cure per mfg instructions.

It's definitely a DIY job. It's easier to change your own diff fluid than to change your own oil, and changing the cover isn't that much more difficult than that.

When you select an upgraded cover, consider choosing one that has a fill hole at the appropriate level so that you can just dump oil in up to the level of the hole, rather than having to measure it. Also, choose one that has a drain plug, rather than one that requires you to remove the cover to drain the gear oil.

DIY for sure. I am not that handy but did it myself just took my time. Invest in a good razor blade to scrape off the RTV - that took me the most time - and a rubber mallet to break the old one loose. There are some good YouTube videos that walk you through it. I went with the Poison Spyder as the fill hole is at stock location for the reason listed above. However, there is a drain hole not on the diff cover on the axle so you don't have to remove the cover to drain (at least on my 2010 but assume they all have this?).

Oh, that could be it! I just remember dealing with a lack of drain hole on another vehicle, and love how handy the drain is on my Jeep.

The next time I'm under there, I'll take a closer look and learn something. Nice catch, Wolfpack!

Yes, there is a drain plug on the differential housing.
