Drive Line Fluid Changes

[bluecrewnuke]

OK, thanks. So those are the same axles.....'19 vs '20? Who builds those axles?

If the trans and transfer case are indeed synthetic I would leave them alone. But the since the diff's are not syntheic I would will probably do them. Mobil 1 has a 75w90LS lube for limited slip. No need to add anything. I put it in my Corvette and it's working great not clutch chatter or anything.

Some what off the drive line topic, how often should the coolant be flushed? I'm coming up on 50K and I've only done oil changes and filter changes, I want to do the front and rear diff. but wasn't sure about the radiator.

Great, Thanks.

I've always had to pull the rear diff cover on my previous trucks. It's not ideal, but not that big of a deal.

I plan on changing diffs and t-case around 40,000 and going to Amsoil synthetic. I tow a boat most of the summer.

I'll also try to do my transmission at the same time. Yes, I know what FCA says about the lifetime fluid but I don't agree. That may get them through their warranty period, but I'm concerned about a longer time frame. I've always done my own by dropping the pan, replacing the filter then disconnecting a line, pumping out old and replacing with new until complete. Sounds harder to do with the new trans so I'll have to do some more research before I attempt that.

I know nothing about vehicles but try my best when it comes to maintaining the ones I own.

I’ve got a 2019 1500 with a 3.92 axle ratio (honestly don’t even know what that means but it’s how I ordered it with the understanding that it would be better for towing my 5,000 lbs boat and trailer). Besides full synthetic oil changes every 5k miles, I did transfer case fluid service and all drive line fluid service at 28k miles. I’ve got 36k miles on the dash now.

What is this Amsoil product you guys spoke of? What product is it replacing? I plan to own this truck until the wheels fall off. I have a Honda I put 180k miles on with just basic oil changes but that thing was only $20,000 new and I didn’t know as much then.

I still take mine to the dealership for any and all repairs minus new tires. Do they use the appropriate fluids or just the cheapest ones?

I used to bring my own brake fluid to the dealer for my Alfa Romeo. Wondering what I need to do now with my truck.

Thanks in advance!

Ahh...I was looking at 2019, you're correct...2020 shows nothing for anything other than engine.
Well, Ram manual specifies 75W-85 front and 75W-90 for 3.21 rear. Volumes from Amsoil site for 2019's are 2.3 pints (1.15 qts) front and 5.7 pints (2.85 qts) rear. Ram manual says level with the bottom of the fill hole

The axle ratio determines how many times your driveshaft spins to get 1 full rotation out of your tires. The 3.92 is a lower ratio (numerically higher) so the driveshaft will turn 3.92 times for every 1.00 turn of the tire. It's a mechanical advantage, that's why it's better for towing. The 3.21 ratio means the driveshaft will spin fewer times to get 1 full turn of the tires, which also means the engine is spinning slower as well, which means it'll save fuel in SOME circumstances.

As far as Amsoil goes, avoid it. It's extra $$$ for oils and fluids that will not do anything advantageous for you. Basic oils and fluids off the shelf at Walmart or the dealership will keep your truck healthy for years. Main thing is to do the maintenance on time, per the manual, at every interval.

AMSOIL provides high quality synthetic fluids, gear oil, transmission oil, engine, etc. as well as some fuel treatments. All are engineered to meet or exceed manufacturers specifications. In some cases, they also allow you to extend service intervals for some systems as well.

If you have any questions you can send me a direct message.

Is there anything I’m missing? I’ve looked at the maintenance schedule many times you always hear something different on here and other forums and I don’t know any better.

Still not sure if I should mess with coolant. Some say every 5 years which I hit this year. Haven’t done it yet.

Same with trans flush at 30k and pan replacement at 60k. I’m not sure if I should or not.

That is impeccable maintenance, you did mention that you owned an Alfa Romeo in the past, so no wonder.

Planning on servicing the transmission this coming spring, at the 80k mi mark right now.
Running Mopar 10 year coolant so several years to go.

From the 2019 Owner's Manual pg 479
"Flush and replace the engine coolant at 10 years or 150,000miles (240,000km) whichever comes first."
