What grease are you using?

I’ve been under my truck a bunch and didn’t notice any grease Zerks. Guess my brain just assumed it wouldn’t have any.

Ya I think it's a commonly missed thing. There's one on each side in the universal joint for the front axles. They're tucked up in there a bit, so you might need to rotate the front hub by hand to be able to see them.

FWIW the F-450 has somewhere around 9 grease zerks on the front end ( :oops: ), so we've got it pretty good.

I have the Dewalt (virtually identical to the Ryobi.)

Works well, but kind of messy, and a PITA when you need to use multiple types of greases.

Well dang it. I've watched some videos on the Lube Shuttle and I think I'm taking a trip to Home Depot to return the Ryobi gun. That really is slick.

Only concern is none of their greases have a dropping point that matches or exceeds the Motorcraft one, but I'm pretty sure the majority of Super Duty owners are just using a generic high temperature grease.


If you go with Shuttle Lube which grease do you think you would use on the Super Duty?

Good question. I might be inclined to use LI400 as it is the “spend money to not think about it” option. 😅

I’d also bet that the Germans conservatively rate their greases…

That said, I’ve read on other forums that even XG11 is way overkill for the front of these trucks.

But I’m no mechanic, hence, happy to spend money to not think too hard about it.

That's the exact conclusion I was just coming to lol. Found this video which does a fantastic job of explaining the different greases they offer and what they are good for:


The description of the Li400 was pretty great. Can be used for pretty much anything and do well at it.

Ok, here's the kit I'm probably going to get: https://advancedenginetech.com/product/lube-shuttle-travel_trailer_greasing_kit/

Color me stupid as this is all new to me, why do you need to grease the front end outside of regular service intervals?
Click to expand...
I plan on greasing them every oil change...so basically a regular service interval? And I plan on doing the routine servicing myself, which means I'll need the stuff to do so.

Gotcha, that makes total sense, heck, I just learned they do not have “A” on the 4x4 knob even thou they have the same transmission as the F150

Lots to learn about thr Super Duties compared to the F150

Yep! Definitely different beasts. All sealed bearings on the F-150.

And as a heads up, the F-150 and Super Duty have quite different transmissions. While they are both 10 speeds, the Super Duty transmissions are far more robust to be able to handle the torque of the PowerStroke. While I'm sure they took learnings from the F-150 transmission, since it came out first, Ford states there's no shared parts between the two.

I suspect that's also part of the reason for the lack of auto 4x4: being able to handle the torque of the PowerStroke in the transfer case.

Was told buy the dealer (ya I know) that the transmissions were the same & only had different programming

Just more proof to take what the dealer says with a brick of salt
 
This thread has convinced me to get the shuttle kit with the Li400 grease. I’ve never had to grease anything before, is there a process for removing the old grease or do I push this Li400 in at regular intervals and allow it to initially mix with but eventually over time displace the factory grease?

Good to know, I'll have to check them out. I hate my current grease gun. That lock and lube is awesome btw, well worth the $20 or so it costs.

I love the LocknLube locking coupler. Working with heavy equipment greasing daily is mandatory and it makes a huge difference. Plus when it wears out they sell rebuild kits for cheap and in 10 minutes it’s like new again. I have it on my Milwaukee M18 grease gun and won’t have another grease gun without it.

I don’t know of a more elegant procedure than just pushing out the old grease with the new grease.

Like, pump the new grease in until only new, clean grease is coming back out.

Replace factory installed joint with a brand new one. Guaranteed no old grease in it then! 🤣

Seriously though, @soop’s answer is the only way I’m aware of and is my plan right now.
 
To follow-up on the Lube-Shuttle grease, before I found the detailed video I linked to walking through the different grease options I reached out to Lube-Shuttle for what they would recommend as a replacement for the Motorcraft grease recommended by Ford for the front hubs.

Heard back this morning with this response:

“The crossover grease is AIRTEC LI400 with a drop temp over 535F. You will have no concerns using Li400 as a replacement, it actually tests better in pressure rating and stability.”

So LI400 was indeed the correct choice. :D
 
Nice to know they have prompt customer service! I’m ordering.

I had a new toy finally arrive at my dealer yesterday. It has 20-30 zerks, at least 10 of which need daily greasing. 😅
