Change Driveline Fluids Early!

[Tor148]

Uh…how often do they “expire”? I was sorta saving up for a set of wheels…

Guess I’m going heavier for my next drain & fill. I put that rear locker to work often.

So in other words, as long as you keep going to Ford and givin' 'em that cash.

Honestly, all synthetic gear oil has FM in it. It does not harm non-LSD axles.

A few thoughts on heavier gear oil:

For decades Ford specified 75W-140 in their 9.75" and larger axles only reducing to 75W-90 in the last few years. The only reason that Ford and every other OEM would reduce the viscosity is to gain more CAFE credits (e.g. increase MPG). This is not conducive to long axle life--did they redesign the bearings, gears and axles? No, and your right foot, a head wind, higher loads, towing, or running at altitude will impact MPG more than a viscosity change ever will.

Dana Advantek axles run much hotter than previous generations. I installed ISS Pro gauges in my Wrangler with D44 M210 and M220 axles and they ran 225°F on the highway unloaded. While I have not checked the Bronco given it is the same design, I can only assume the same temperatures. In the Wrangler, FCA chose to reduce the oil capacity from Dana's design, though the Bronco does not appear to have that issue in the rear, but the front is a joke--1quart capacity.


75W-110 was the upper viscosity range of 75W-90 before the J306 tables were updated some years ago, so if one wants heavy duty 75W-90 oil, then 75W-110 should be the choice.

Last, but not least, Dana recommends 75W-140 and they have no stake in the MPG game.

Hope this helps!

So this would be true on my Brapto

Yup!

THANKS!
Great explanation, have to laugh at CAFE Standards from Gear Oil, really.

It ties to everything they do, from introduction of plastics to the maximum extent, to lowering viscosities and capacities, to the introduction of 8+ speed transmissions, and the list goes on.

xW-12, xW-16, and xW-20 (and soon to be xW-8) engine oils were not created for engine longevity in the slightest...

Get a Ford Rewards Visa and use it for everyday purchases. I earn a lot of points annually doing this and get a lot of free stuff. Done a few oil changes, 6.7 Power Stroke included, got SAS flares, black lug nuts, hood protectors for both the Bronco and Super Duty, and lastly the FP Diff Cover in this thread.

I'm buying stuff every day, might as well earn points while doing it!

Carbonsteel is right. I just changed the fluid in the front/rear differential, and the transfer case on my 2016 F150. It's a very easy job. My dealership wanted $275 for each differential and $75 for the transfer case. I used all amsoil products and it cost me $115. This was the first time I've ever done that on any of my rigs. YouTube is your friend. Wife's Bronco is next.

I don't see how people afford to take their cars to get serviced. If they only new how easy some of these tasks are, they would probably be dumbfounded by how much they are being charged.

It's not that I can't afford to take my stuff in, it's I'm doing it and know it's getting done right and I'm saving a lot of coin by doing it myself.

Thanks CarbonSteel! Ordered the Ford Performance cover today using the promo code and FordPass Rewards! Any chance you could post a picture of your installed cover?

I hope to do that on Friday along with what I will use to replace the plastic clips for the brake line.

Interested in the clip 'fix'
Do you have a parts list?

Let me get it installed and then I'll post exactly what I use to replace those plastic clips. Let me guinea pig it and make sure it works.

How long after you ordered your Dif Cover did it take to get to you,? The only other item I ordered from them took over a month to get.

I have time, waiting for the cover anyways. Did order all the oil for both my FE and the Braptor.
I have been looking for a cover for the Braptor, with a drain plug, but no luck so far

About 4 days (may be less, I would have to check).
