How to change the rear differential fluid on a Dodge Ram 2500

In this video I will show you how to change the rear diff fluid on a 2001 Dodge Ram 2500 with a Dana 70 and Cummins turbo diesel. I use the Mopar limited slip additive, a Lube Locker rear gasket, Amsoil Severe Gear 75w--90 oil and 3 oz of Archoil 9100 friction modifier.

[@patrickthomas6170]

Tip. Wire brush and spray top of diff covers before cracking open . Prevent dirt debris from falling right on sticky oil covered gears. Ask me how I know . Also front diff access made easier by gentle lift on front with jack stands in place but tires still touching ground. Use Harbor freight fluid transfer pump for anything more than 1-2 qts or else you will be pumping for days.

My cover looks a little different (Doesn't have bent flanges, just flat at the edges.). I'm having trouble getting it to break the seal. It is glued on. I don't want to bend the flange. Been using a small screw driver on the bottom edge. A friend said to pry in the flat area half way up instead of at the bottom. Not sure how hard I should tap the screw driver. Any suggestions...

Thanks for the video. Im going to service my husbands differential. Ive never worked on my husbands truck the way I do now. I just did all the brakes and noticed the rear hub seal is leaking. So ill service it after I replace it. Any extra advice doing the whole thing? I figured since I was doing one side I should do both just to get them out of the way. The seals are about 10 each how much was the kit you got and where did u get the kit?

[@mcgarrett9124]

Good info

[@BoostNBalast]

Is it just me or did the guy never show how to make sure it's up to level?

[@coltondost9890]

Very nice video. helped me out

[@cyrusullmann9917]

Is this similar on a 93 dodge w250 4x4 Cummins 5 speed? And is it better to use a gasket or RTV silicone.

[@JodBronson]

+Cyrus Ullmann - Save time and avoid mistakes... Use Gaskets!

[@artperez1213]

Where do I get the gasket? Could you please answer my question. Thanks.

[@yeti7520]

art perez Look it up online.

[@jimdailey1018]

art perez fel pro.

[@repairvehicle]

There's an easier way to add fluid without attachment or pump.

[@JodBronson]

+repairvehicle - Let me guess! Buy your shits? LMFAO !!! 😀😀😀😀😀😀

[@slvrwrx25]

so the first half of the video is literally just a recording of the rear diff. geez

[@michaelconklin4533]

slvrwrx25 , it’s a 16 minute video. That’s enough time for a beer break. Don’t stress.

[@brandonnichols4649]

Math must not be a very important subject in school wherever you live because last time I checked 128.9° -111° ain’t 4° just saying not trying to bust you and push you down, but you just seem a little drunk maybe

[@jeffgoodman4297]

Glad I'm not the only one that noticed that. I would say there was a significant reduction in temp.

[@robbelle3707]

Hopefully I don’t make anyone cringe too much but how bad is it just to drain and refill if yours has a drain plug?

[@cowboydown30]

Please don’t drive even a little bit without diff fluid. Bad idea. Amsoil is good stuff though.

[@terryhenry8243]

Good video, The only concern would be that all these differentials are specific in types of oil and friction modifiers. Some yes, and some no depending on model year and axle spec. Not all the same.

[@researchandbuild1751]

How many quarts did it take to fill?

[@jimbouchard528]

I never saw any gasket come off that easy in my life

[@kolinken9524]

Thanks for the video. My truck is exactly like yours. By the way, I have the official Ram Truck Service Manual which I paid $120 for when I bought the truck (I'm still upset about that). ;- ) Our trucks with the "Limited Slip Differential" or as GM would call it "Positraction" Dodge calls it " Trac-lock." Here are the instructions word-for-word from page 3-132 and page 3-153 starting with putting the cover back on. 6) Apply a bead of Mopar Silicone Rubber Sealant, or equivalent, to the housing cover. 7) Install the cover and any identification tag. Tighten the cover bolts to 41 N-m (30 ft. lbs.) torque. 8) For Trac-lok differentials, a quantity of Mopar Trac-lok lubricant (friction modifier), or equivalent, must be added after repair service or a lubricant change. Refer to the Lubricant Specifications section of this group for the quantity necessary. (My note: There is NO quantity listed of the Mopar Trac-lok lube listed. Probably just the 1 small bottle). 9) Fill differential with Mopar Hypoid Gear Lubricant, or equivalent, to bottom of the fill plug hole. Refer to the Lubricant Specifications section of this group for the quantity necessary. Page 3-153 Lubricant.......Thermally Stable SAE 80W-90 Lube Capacity 4x2...... 3.22 L (6.81 pints) 4x4...... 4.80 L (10.125 pints) Axle Ratio...... 3.54, 4.10 Torque Plug, Fill Hole ...... 34 N.m (25 ft. lbs.) Bolts, Cover ...... 41 N.m (30 ft. lbs.) RWAL/ABS Sensor Bolt ...... 24 N.m (18 ft. lbs.) Note one of the nice things about this Service Manual is that it has a nice set of graphics showing wear patterns on Pinion and Ring Gear teeth. Hope this helps somebody.

[@alexc7641]

Kolin Ken thanks! It helped me!

[@scoutsniper8688]

I have this exact same manual..and you are spot on correct!

[@kalebkaysen2482]

I guess im asking randomly but does anyone know a way to log back into an instagram account? I somehow forgot my login password. I love any assistance you can give me!

[@braylenalberto6461]

@Kaleb Kaysen instablaster =)

[@kalebkaysen2482]

@Braylen Alberto i really appreciate your reply. I got to the site thru google and im waiting for the hacking stuff atm. I see it takes a while so I will get back to you later when my account password hopefully is recovered.

[@kenuber4766]

God ,I thought this was a fluid change video. More like you work for NASA!

[@SteveRivett]

I like to use a carbide scraper to clean the gasket faces. It peels off the RTV without a lot of drama. I just stuff rags around the internals before I begin scraping so that I don't have to clean up as much.

[@MrSerrya]

Good detailed instructions, thank you

[@DieselWorld]

+Serry Allam Your welcome!

[@alexmurphey85]

really liked the video just out of curiosity do u have one on u-joints? i came across your video because someone said my sound in my 98 ram 3500 8.0l v10 was either a ujoint or diff fluid, the sound is similar to as if a rock was rolling around in my rear wheel between 8-15 mph

[@dougmaus4468]

Thanks for the video! I have basically the same differential on my '97 Dodge 2500. One concern I have about that gasket---it says tighten to 35 ft lbs. But the Dana 70 spec says 30 ft lbs. I would hate to break a bolt overtightening it

[@jimdailey1018]

Doug Maus use the lesser amount then check for leakes.

[@poke777890]

On that type of gasket you need lock tight on the bolts. And Pipe Dope on the fill plug. This guys will miss you up on your differential change. Lol

[@blakeking985]

thanks for the video this is gonna save lots of money but it it the same on the front axle if its 4x4 as far as checking the fluid level?

[@wigginender7241]

My OCD I would have cleaned the magnet that sits in the reservoir

[@whiteknight7729]

Dum question... How do I know if I have a anti-slip versus limited slip diff?

[@whiteknight7729]

I'm also adding Amsoil lubricant. Just need to understand if I need to add anything else.

[@dennishaggett5169]

Great video. Thanks for all the information.

[@jaantobro5271]

Hi! You didn't specify the quantity of the additive. The whole bottle goes inside?

[@emmanuel9413]

Dear sir, i have not understand why you take temperature of the differentiel, can u explain please. Sorry english not my mother tongue

[@jesselpatton1]

emmanuel by testing the temperature it shows how well the differential fluid is working hotter not working so good cooler thicker working better.

[@jimcarroll5283]

Jimbo thanks for the video

[@davekana8388]

Many of the synthetics, 75-90 or 75-140 say they contain the required limited slip fluid. Russell, what did you use to refill a pump or just squeeze the bottles in? Think I'm going to use the gasket too, thanks, Dave.

[@rodolfoplasencia4953]

Great vid! You can also fill it up as much as you can, to don't run it w/o dif oil, level it, then fill up to the top mark which in this case is bottom of oil plug.

[@jonathancastillo2491]

Where did you buy that diff service kit from?

[@hossmonkey1]

From website: 2500/3500 Model axles DO NOT REQUIRE any limited slip oil additive (friction modifiers). 1500 Model rear axles equipped with a Limited Slip Differential require that 5 oz. (148 ml) MOPAR Limited Slip Additive be added to the gear lubricant. Refer to “Fluids, Lubricants, And Genuine Parts” in “Maintaining Your Vehicle” for further in

[@piecesmotocrossparts788]

NOTE >>>it is Important to re-check oil level after a few miles ride !!

[@BoostNBalast]

How!?

[@guillermomartinez-clavijo7685]

How do I know if my Jeep Grand Cherokee WJ 4.7 with Quadra Trac II needs the slip additive?

[@ubaldo24v81]

Do a burnout

[@jonnyfive9163]

That's definitely not a Dodge Ram

[@GwinnettLawns]

It sure is cappy. 2500 with the Cummins.

[@uslt5028]

75w110 I use only

[@uslt5028]

15years using already

[@frontlinemedia4270]

That's not enough driving before drainage.

[@DieselWorld]

Its just plenty.

[@yeti7520]

Comprohensive (sic)? Lol

[@fostererickson9422]

What kind of bit do you use to get the fill plug out? What size is it?

[@scottbarlow1397]

Use a 3/8 or 1/2 ratchet and a 3" extension

[@woodkoval1293]

would it do damage if I use limited slip oil even my manual said it doesn't require limited slip ?

[@DieselWorld]

It wont hurt it at all.

[@woodkoval1293]

+dieselworld. thanks

[@imranhajee4136]

Great video

[@jimdailey1018]

Pit a mag hytec cover on.

[@jdirt1982]

Waste of money ..

[@garyl3819]

Watch Gale Banks videos on flat back dif covers. Not an Improvement even though they look great.

[@colteng9721]

I wanted to put one of those fancy covers on as well but then I saw that video a while ago showing the difference between stock and aftermarket covers... Well its one of the occasions where I'm leaving it stock lol

[@bobabooie6389]

​@Gary L thanks

[@heydude76]

thank you for this video!!! you have motivated me to tackle my rear diff and I can stop telling myself lies that its fine and it can wait thank you again and a video on the front diff would kick ass:)

[@DieselWorld]

+heydude76 Thats great. My truck is 2wd so no front diff video to be done.

[@TheRealJRC]

Page 399 of my owners manual to my 2005 Ram 2500 5.9L diesel says DO NOT ADD LIMITED SLIP ADDITIVES in all caps. I cannot seem to get a straight answer here on what is supposed to go in there. Do you know? Is the locking rear axle the same thing as a limited slip rear?

[@9thGenAccord]

+Subaruguy8508 Look on the rear of your diff. Is there a tag that says it needs limited slip fluid. No a limited slip and locker are not necessarily the same thing, but many times people get them confused.

[@DobermansRock]

I don't give a shit as long as its the right weight oil. All the rest is a deal to get money. Dodge said it would be some crazy price for their special fluid. It does not matter. Anything beats running it dry or full of water.

[@RandallsRestRelaxation]

Awesome... Thanks

[@jeffdorough5289]

Thanks for wasting 48 seconds of my life in intro and title.

[@DieselWorld]

Are you always an A$$ everyday in life?? Your a moron for even spending another 60 seconds writing a comment that ignorant.
