Today I was putting new front brakes on my truck and noticed the front left wheel bearing would make a small amount of noise when spun and it spun much too freely meaning lack of grease. So I took it off suspecting that I would have to replace it in the near future. As I was looking it over I noticed that there was grease inside where the ABS tone ring is so I figured that maybe if I pumped grease into the abs sensor hole that it may start to oozz out the sides of the sealed bearing. So I sat there with my Lincoln grease gun pumping for what seemed like forever and then it finally started to oozz out the sides SUCESS! So I let it oozz until all I saw was fresh grease. Picked up the wheel bearing and spun it around, it felt like a brand new unit that was filled with grease and was nice and smooth. I have pictures and will post them later.
Ryan, You have discovered a great way to grease the main front 4WD wheel bearings. I have an article in here on it but can't find it and they should have put it in the FTE folder. Mine are still doing well with no grease on rotors etc. Great job and reps to you!
By the way, Timken uses Exxon/Mobil Infinitec 152 to lubricate these bearings at time of manufacture. It is a very heavy-duty, NON-moly, lithium-complex-based grease, blue in color.
Cookie88, one of the 7.3 list moderators, has been doing this to his hubs for years with no failures.
He's still around.
I've been doing it for the last two years. I just completed a round-trip cross-country Los Angeles to St. Louis. Lubed mine just prior to leaving. One of my hubs has 190,000 miles on it.
Not that it means anything, but I didn't end up in a ditch....
OP last posted October of 2007. Maybe he went off the road after a bearing failure.....
I just ran across his brilliant post when I was looking for my old thread and had to give him reps. I'm sure his bearings are still happily cruising along. I did this grease job to my "non greasable" hubs months ago and it is the best invention since sliced bread and all you na sayers are missing the boat.

Thanks POP, I found it as you were posting but I saved it this time..........interesting about the grease and as you know; no bearing or grease will last forever. They did come close to lasting the life of the trucks though, but close only counts in horseshoes and tiddlywinks.
So if I do this on my 04 SD, what grease is the best to use? You guys that have had the good luck doing this, did you use that Exxon/Mobil blue grease or a good quality bearing grease? I have read in the past not to mix different types of wheel bearing grease. Who sells that blue grease, I don't think I have ever seen it. Thanks for your time and information.
I used a high quality NLGI 2 grease when I did one of my fronts this way. That was over 6 months, 5k miles ago and no problems so far with mixed grease, etc. I didn't push it in until it pooped out the seal, I just added as much grease as the hub would contain internally.

The purpose of my correspondence with Timken was to determine the soap base, which is lithium. It's NLGI Grade#2, and it's and NON-moly. Meeting these three parameters should get you into the ballpark.
The Exxon/Mobile stuff will likely difficult to find, so I wouldn't spend much time looking.
