Does rear diff have a reusable gasket?

[Tonka Bronka]

1. NOTE: Make sure to note the position of the gasket prior to removal.
   NOTE: Make sure the component is seated at correct position.
   NOTE: The gasket is to be reused unless damaged.
   Remove the gasket.

1. NOTE: Use care when cleaning the differential housing and its cover gasket mating surfaces.
   Clean the gasket mating surface of the axle and the differential housing cover.

So flip, it does have a factory installed reusable gasket? Front also on the Badlands? Thanks.

Front is sealed halves but does have a drain and fill.

1. Remove and discard the front differential fill plug.

   WARNING: Be prepared to collect escaping fluids.
   Remove and discard the front differential drain plug and allow the differential fluid to drain.

Wow, the fill/drain plug is explicitly a single use item. Ha.

That’s great. Thanks flip, I haven’t taken a look yet.

OP- I based my answer off incorrect info I didn't verify first, my apologies, and thank you @Exomodo for setting me straight. Maybe a gasket spec'ed for a '18-19 Wrangler would fit? I just don't see the point in messing with a reusable gasket in this application.

I own an auto repair shop, and I can say from experience that the best odds of not have an oil leak are to reuse a factory reusable gasket, if the application comes with one.

The problem with reusable gaskets with metal inserts is the bozos that reef on the factory bolts that takes something like only 15-30 inch pounds of torque, not 50 foot pounds of stupid...

Disposable front differ drain plugs are new to me.
Glad to have read it here then find out the hard way ..... far from home.

are the oem replacement drain going to be disposable also?

Next, subscription diff plugs! Subscription lapsed? OOPSIES! No more differential...

These are considered "one time use" hardware. No rhyme or reason why some fasteners are and some aren't. Torque to yield is self explanatory, most of the other hardware is due to factory applied sealer or loc tite. I guess they think we are too simple to read what it takes and apply it correctly so they just say replace it.

I just ordered Amsoil Severe Gear 75W-90 for my diffs. I was going to suck out the old fluid and fill but I would rather take it apart if there is a gasket available. My 2007 Super Duty had no gaskets and ended up installing Mag Hitech covers with O-rings. I had trouble getting the stock cover to seal with just Permetex.

In the FWIW department, Currie Enterprises (who's business is building rear ends) requires non-synthetic diff fluid, and using synthetic gear oil will void their warranty. Also, whether conventional or synthetic the metal wear bits still float around inside the diff oil and it should be changed occasionally. Personally, since conventional gear oil in diffs has proven to be totally adequate to protect rear ends for years and years, and the fluid should be changed now and then anyway, I question the benefit of synthetic gear oil. Not trying to be disagreeable, just presenting another view.

Changing diff fluid has always worked for me in many performance vehicles, I also am a big fan of installing a strong magnet with epoxy at the sump area

Discussion is good. I tend to use what I have used., mostly because I have used it and nothing blew up.

Sometimes when a product is no longer made I panic.

Additionally, I've been told mixing synthetic and conventional differential oils has the same effect of putting Roses Lime juice in Bailey's Irish Cream... otherwise known as a "cement mixer", only extra destructive...

I believe Ford specs a synthetic gear oil for their Bronco differentials and the cost between synthetic and conventional gear oil for a couple of quarts is negligible. As far as regular changes regardless of oil type, it’s been my experience that once the initial mating wear materials are removed and a quality diff fluid is installed, the fluid always looks clear when checked on a regular basis. Can you elaborate on why CE would void a warranty if synthetic oil is used in their diffs? Thanks.

Can you tell us were you learned this.
