Differential Fluid Change - Jeep Wrangler JL Rubicon 392

[@nicktheamsoilguy]

Lucky you didn't loose the cap to the bottle inside the differential. You needed to take the cap off before you cut the nipple.

[@TheNotSoOrdinaryCarGuy]

Yep!

[@jlc2transport308]

How many miles are you doing these at

[@TheNotSoOrdinaryCarGuy]

It’s recommended every 30-50k miles. I did this one around 25,000 and will probably do it ever 25-30k miles.

[@stevenwalker1591]

Doesn't your Rubicon have the M220 (Dana44) rear axle? If so it requires 75W85 gear oil.

[@TheNotSoOrdinaryCarGuy]

The specs from Spicer Dana say to use 75W140 on an M220 rear axle. I figure it can't hurt. Some say to use 140 if it's under a lot of stress or towing.

[@stevenwalker1591]

Just a FYI in case you have a warranty claim. FCA holds the warranty and not Spicer Dana will do anything to say no to a warranty claim.

Mine is 75-140 also jeep gladiator 2022 sport s max tow rating

My rear differential on my 23 doesn’t have a drain hole gotta pull both covers unfortunately.

[@TheNotSoOrdinaryCarGuy]

I wonder why they would take that feature away?

[@DeadOnTrail]

@@TheNotSoOrdinaryCarGuy no clue! But the spot is still there on the diff. Just not drilled and tapped. Mine just hit 15k miles gonna change my transfer case and diff fluid tomorrow need to pick up new bolts for the diffs mine are ground in half!

[@michaelrocole7174]

My 2022 has no drain plugs its a Rubicon Unlimited 4-door. I wonder if it was a supply issues

[@TheNotSoOrdinaryCarGuy]

@@michaelrocole7174 Perhaps anything to cut costs? How much is it to drill and tap a hole?

[@WreckedBrewery]

Neither front or rear differential in the '24 has a drain plug either. Sucks. Have to pull the covers off.

[@fredpassafiume2218]

Can you reuse the diff cover seal.

[@TheNotSoOrdinaryCarGuy]

Yes!
