Does anyone know what type of wheel bearings grease Suzuki uses in the stock wheel bearing? I need to add a shot to my bearings while the wheels are off. Yes, I know they are sealed but I have the key

So help me understand, you have sealed bearings, but your going to add grease to them, and this is good why ? Is this not why these bearings are sealed, to keep the right amount of grease in and the crap out, adding grease will only make things worse in my opinion.
I know these are not high speed bearings, but I remember my dad talking about how many times he had to replace almost brand new bearings, because some maintenance guys would grease up the sealed bearings, this generated more heat, this caused the grease to liquify and run out and since there was now no grease the bearings would seize due to no lubrication.
I think if your worried about them not being any good, it would actually make more sense to replace them with new ones, they are not expensive, and will last you a very long time....
my 2 cents worth.....YMMV

I'm not sure why so many people feel such an irresistible itch to stuff their bearings full of grease, but this topic comes up far too often.
There are several reasons you should not do this.
1) Many greases are not chemically compatible with each other. Since no one knows exactly what was used at the bearing factory, you don't have any way to choose a safe grease.
2) Suzuki original bearings are sealed on the outside and open on the inside. Since removing the bearings destroys them, doing this doesn't make sense either.
3) You do not need to add grease to sealed bearings. If you have any iota of doubt about bearings, simply replace them -- they're quite cheap, since they're standard metric industrial bearings.
4) Sealed bearings are manufactured with the correct amount of grease. "Stuffed full" is NOT the correct amount of grease.
5) Sealed bearings are made to tolerate FAR higher speeds and loadings than our puny motorcycles can generate. Motorcycle wheel bearings never actually wear out -- they die because the seals fail, which allows water in, and eventually corrosion begins. Incorrect installation also kills lots of bearings.
6) Removing the seals to stuff in more grease inevitably damages the seals (even if you're really, really, really careful), hastening the demise of the bearing as in point 5. Also, see the post above mentioning that excess grease more easily liquifies and escapes, which makes a mess and kills off the bearing early.

My bearings have 79, 670 miles on them. The seals and bearings are in perfect condition but there is less grease in them than there should be. I know how much to use I just don't want to mix different types of grease. Why dont I change them? Why should I? I think my japanese bearings have shown they can withstand 79, 000 miles. I doubt the chinese bearings I get to replace them will make that mileage.
I guess the short answer is "nobody knows what type of grease is in a factory Suzuki wheel bearing."

We pulled the seals off a Mountain Bike for a strange feel on the Crank.
Took it apart and looked at the balls, were scored, odd?,, (bicycle less than a year old).
We hit one of the balls with a small hammer and it squashed almost flat, like it was made of tin.
Sure, its a bicycle bearing (China) but do you want to buy the cheapest bearings you can find?
Took a new bearing seal off (easy to do carefully with a ExactoKnife) and notice the "lube" was just a small smear of grease in one spot, not much,,..
Packing the bearing with a lot will blow the seals off.
A little known property of grease, is its main purpose, is to Weep Oil.:-$
Oil and grease will Evaporate over time, all by itself.
Grease will leave a dry residue behind.
So a smear of grease all around the Raceway Cage will keep it lubed a long time, without getting in the way.
A appropriately sized and well lubed bearing in a motorcycle should outlast the rider.
I check All bearings I buy now for good smear, seals or not.
Any kinda grease will work, but considering a tube of grease lasts me a decade or longer, buy the best Marine Grease you can find.
I have thoroughly cleaned dirty/dry bearings and relubed/reused them, if they are still tight, but considering the effort to remove/replace bearings, just get new ones.

I was taught by Steve to use Moly Grease. And, get the most pure Moly you can find (highest % to other stuff)
I've used it on other Non-Suzuki applications. Doesn't get runny and drip away in the heat, or rain. Used on other folks bikes, they are happy too.

That Moly grease is specifically for the driveshaft splines.
Yeah, it might work in other applications, too, it just happens to be the best grease for the splines.
Other applications might specify lithium or general greases, I would not use moly in them.

In case this helps:
The GS850 Suzuki Service Manual from 1979 does not list the type of grease to use. Moly is listed as a special material, but not for wheel bearings. The Haynes manual from 1980 specifies lithium high melting point grease for the wheel bearings. Both manuals talk about washing the bearings in petrol, spin testing, and repacking.

I use Redline CV-2 grease with Moly.
http://www.amazon.com/Red-Line-CV-2-Grease-Moly/dp/B000J3ICB2
It's a little more expensive, but it's good stuff.

I use Valvoline or Mobile 1 syn wheel bearing grease, just a tad does it. The bearings I just replaced had 29,000 miles on them and had been repacked using the Valvoline syn grease, when I opened them up, they still had plenty of grease and looked pretty good yet. The stock bearings i had to replace within 11,000 miles, they went to crap in no time, specially the front ones with the open back, they pretty much destroyed themselves in less then 5,000 miles.
