My reading seems to indicate that colors are often a branding thing. Lithium complex is compatible with many other types of grease but not (for example) polyurea based grease such as Lucas X-tra Heavy Duty grease. Here's a compatibility chart for your reference...

Yes, put some kind of grease on the splines, preferably new. GAA is a lithium complex grease. I think you said that the grease you're using is also lithium complex, so you should be fine.

Eh, depending on what kind of greast the previous owner used, and the heat that the truck may have sat in, the grease in the knuckles could be OK. Well, assuming that he didn't do any deep water fording and wash it out. When you get the chance, remove the boots and scrape out all the old...

NO, the axle is isolated from the differential oil in pre-939 series trucks by seals. You pack the knuckle full of grease to lubricate the axle CV joint.

I always seem to miss the easy, obvious solutions.

I re-packed my bearings completely by hand. It's not a crime. :) You just gotta keep grabbing handfuls and pushing it in, working your way around. You can easily get it as full as any bearing packing tool, it's just messier and a little more wasteful.

So you didn't waste your money on that socket.

Just to provide a more complete response to what I said earlier- I froze my seals and I used @Brutacus' method using the hub flange to carefully drive it in. By the time the seal was installed, it was warm and pliable enough to reassemble everything.

Freeze 'em. Do think the rubber gets damaged in winter time? ;)

Blah, blah blah. More photos. This thread is mainly to help folks with the older 5 tons and clear up some differences between TM's and Youtube. I saw a guy pull a front drum on Youtube and his inner seal and bearing remained on the spindle when he pulled the drum. This was on a 939 series truck...

Finished up the driver's side yesterday. The driver's side was in even better condition. The grease was still in solid form and plenty of it. Frankly, the only reason I cleaned and re-greased everything was just to get it all on the same maintenance schedule. No axle tube leaks, no corrosion...

Well, the new tool broke the final lug nut free in seconds. I did crank on it a few times and had a moment of concern as the tension built up but it let loose with a good bang and puff of rusty dust. I did check beforehand, and it's the proper stud. No infiltrators. ;) The tool is definitely...

Good point, I should have had some spare studs and nuts on hand. Fortunately, everything had gone smoothly and without damage...up to the point of this one, stuck nut. Thanks for the product endorsement, it makes me feel confident that I'll have that nut removed by this afternoon. It's...

Hey gents, Thanks for all the wise responses. First- I have not removed any lug nuts, only slightly loosened them. This will keep the wheel at the proper attitude while I work on the final nut. Second- Are you @#$! kidding me??? "Infiltrator" huh? I will check that first thing when I get...

Ok, I'm in a bind and seek the wisdom of the Big Truck People. I'm prepping to do the driver's side of the steering axle. I figured I'd start by breaking the lug nuts loose and remove the tire tomorrow, after tonight's rain. I have ONE lug nut that absolutely will not let go. I've tried: -...

Wow, that thing is a beast. I (mostly) quit battery operated tools because the battery design and shape changes every year, making buying replacements a hassle. I understand why people love cordless tools, though. I use the military geared lug wrench and air-impact gun. I also carry a hose and...

I hear you on the "working alone" part. At least I have access to parts and materials. I will say this- Buying the proper TOOLS greatly reduced the struggle and kept my morale high while doing the work.

Robo- THANKS for posting those links, especially the 5-ton rear axle link. The 5-ton rear axle thread just answered nagging questions I had about whether the rear axles were "wet" or "grease" lubricated. The photos of the process highlighted the differences between the rear and steering...

Quick greasing tip which I learned yesterday (and read about in the forum somewhere): If you do decide to follow the tech manual and fill the knuckle with grease, It will take FOREVER to pump it in via the grease fittings on the top and bottom of the knuckle. I shot one cartridge in at the top...

I did some looking around and it does seem that the M39 series 5 tons and M809 series share a lot of parts. For example, the inner hub seal that keeps the inner wheel bearing in the brake drum is shared by both trucks...
