Any brand name #2 lithium complex grease with moly, or for that matter, almost any #2 grease will work. I repacked tapered roller bearings used on front wheel spindles for years with #2 wheel chassis grease and never had a failure. It's not rocket science. Sixty some years of vehicle ownership and I personally don't recall any instance of wheel bearing failure. Last wheel bearings I repacked was on a 1984 Honda Accord which had tapered roller bearings on the rear wheels. Next Honda I purchased had sealed, ball bearing units. Same for the Toyotas down to the one parked in the garage.

True it's not rocket science just tribolog. ๐Ÿ˜€
You are comparing Japanese engineering to American brute design. ๐Ÿ˜€
In all seriousness I know you are right but I enjoy examining lubricant specs and trying to select the best.

Wheel bearings require not just a Grade 2, but also EP additives and resistance to elevated temperatures.

Roller bearings are roller bearings. And after you have picked a grease, repacked the bearings and are on the road again, how are you going to know if you picked the very best? The Valvoline product posted above by Oildude will work as good as anything you pick no matter how many specs you review. Go for it OK. From a Tahlequah dude via New Mexico,Colorado and Nebraska.

I wont know and most likely if I have a failure it wouldn't be from lubrication failure as potholes or age are far more likely.

^ this is what Iโ€™ve been using for many many years as well. Canโ€™t get it locally so I have stock piled it from summit with other orders. I get tubs and tubes for trailer axles.

Anyone have the data sheet for it?

So I did some math and if I did it correctly it looks like those bearings have a DN number of 34,513
And obviously lots of shock loading.

So I applied that number to some charts on Machinery Lubrication website and I came up with it would require NLGI 2 grease but I can't find a good chart for selecting the base oil viscosity.
I was really surprised that the rpm's @75 were so low. It would be about 798 rpm.

Sorry I never answered this.
It is a 2 wheel drive single rear tire 2000 F350 v10 with a 9 ft service bed.

Here's some real world for you. I've owned 20 83-93 5.0L fox body mustangs over the years and put over a million miles on them collectively. I used to run with a crowd of 5.0L drag racers (for 15+ years.) I knew dozens of Mustang and "Ford" guys that would own nothing but Fords. We were all car guys ...and girls. I don't remember one single wheel bearing failure or one single U-joint failure on anyone's Ford vehicle. Ford used to put top quality bearings in everything. For the 1996 model year Ford started using bearings made in Mexico and elsewhere in every part of the car. Bearings immediately began failing. It was common for a 1996 mustang to go through 5 or more transmissions under warranty as Borg Warner was moved to Mexico and became Tremec Transmission. I knew guys that had these problems and several of us worked in different Ford service departments and I saw and heard the stories. I had a 1999 Mustang GT. My last. The differential carrier bearings made a racket from day one and never quit. The throwout bearing exploded 50 miles from home and I had to drive it without using the clutch to make it home. One of the front wheel bearing ASSEMBLIES went out. They had started using these "wheel bearing assemblies" that were probably Mexican or Chinese. Who knows what kind of grease went in them.
Here's the point... Ford never had problems in the old days with good bearings and the antique "Special Moly EP" as ford called their grease. As others mentioned, Valvoline has made a version for decades. I still have a mostly full beautiful white, gold leaf and silver leaf tub from 1992 because I only used it once back when I was young and energetic and repacked two hubs for good measure after turning a set of front rotors (the fox bodies had small brakes and we used to regularly make them glow while street racing.) But the Moly EP never let any of us down.
I'm getting at this: You have a bearing issue, not a grease issue. The bearing is the failure point these days. Look for Japanese or German bearings. I have a complete set of Japanese, German and American bearings and races new in boxes to fix every location in that 99 Mustang rear end. I never used them, and probably never will because the 1992 5.0L coupe I still have (same 8.8" as the 99) has a high mileage rear end that is as good as the day it rolled out of the factory. The only way possible you'll need more than Ford Moly EP is if you descend that imaginary 10 mile hill while hauling 10,000 pounds... riding the brakes the whole way... In which case I say go for the more temperature resistant Synthetic. But I bet the Moly EP will still lubricate better in 99.9% of cases. And just so you know, The Moly EP is a light consistency. Not a thick mucky grease like so many. Try it. You'll like it. And remember, a Tapered Roller bearing in a 1987 Ford truck is basically identical to a 2020 model. Its old technology.

To add, for all the years i handled wheel bearing warranty for our company, i have never seen one fail because of inadequate grease. Not one.

Thank youall for all the replies. I have learned a lot and I enjoyed examining grease a bit closer.
What I learned is that normal grease really is the best for wheel bearings.
Also I thank everyone for all the personal experiences.
I guess now I just have to choose between using some of the 30 gallon barrel that I have access to for free or buying some from my favorite brand. Either way it sounds like I wont go wrong.

Does anyone have any tips for an amateur on packing bearings?

Since I moved to Oklahoma I wont be descending any hills. ๐Ÿ˜€
Our biggest hill is labeled a mountain and it has a 15 mph limit. ๐Ÿ˜€
