The first thing you do is you drill and tap your carrier and put a grease zerk in it.
second you drill multiple small holes in the spacer about 1/4 inch or so i think i did 4 rows of 5 totaling 20 holes but have to be exact.
third and prob most important is with the bearing itself, its a sealed bearing so what you do is take a small screwdriver and pop the inner cover off exposing the actual bearing, throw the cover away and put together like normal...

take off both covers...put seals on and all that put everything back together and fill with grease[/color:kcbs3i3n]
 
this is what the previous owner of my warrior did... but im still undecided on what to do with the outer seals of the bearing....

its seems if you leave them there the just end up blowing out when you pump the grease in.... i have 1/2 a notion to just take them out completely... dare i say it, polaris does it this why and as long as you keep them greased my dealer says they will last forever
 
What's your reasoning behind drilling out the spacer? All that's going to do is pump grease through the spacer and between the inner bearing race and the axle, completely bypassing the bearings.

When I did mine I intentionally left both seals on the bearings. The benefit of this is that it slowly will allow the grease to work it's way through, sort of like an automatic feed system, instead of forcing everything you pump right on through to the dust seal. This way actually created some pressure within the carrier, and time released the grease through the bearings. It must be working, because I used to go through axle bearings about once a year, and they've been on that warrior for 4 years or better now, and are still like new.
 
i think the holes in the spacer are just meant to distribute the grease faster and better.. mine is the same whay but they only drilled two lines of four (i think)
 
one thing i noticed... i filled the carrier with grease and then ran it for a awhile.. then i decided to see if i could get some more in and low and behold i got a ton more in it... seems there was still air trapped in there and i took a bit to work out
 
the reasoning for the holes in the spacer are so you have more grease in the carrier and that the spinning axle will spinn through the grease causing it to push out through the holes and get to the bearings( in theory.... thats what the guy told me) and its been together 5 or 6 years now and everything is still good and tight... just checked everything yesterday
 
it will hold what seems like an impossible amount... just keep pumping till it comes out...
 
haha yea i know a couple of times i have put grease in mine and it pumped water out. but those bearings have been in for over 10 years now (bought it in 1997) and they are still tight, i just keep them greased.
 
hmmm .... this is cool i know its kinda old .. but im pretty new here so its all new too me , is there anyone that has this done that can take some more "indepth" pics of what and where to drill , id like to do this to mine ... thanks !
 
ok .. so when you say drill holes in the spacer , i assume your talkin about the spacer inbetween the bearings....the steel cylider that keeps the bearings apart on the inside of the rear carrier , might sound like a stupid question but,.................the only stupid question is the one not asked:)
 
Don't drill any holes in the spacer, there's absolutely no reasoning behind that. All that does is force grease between the spacer and axle, which doesn't have any moving parts. Waste of time and waste of grease. The only hole you need to drill is the one in the center of the carrier itself. There's really not much involved that really warrants posting pictures of it. Simply drill a hole the correct size, tap threads, screw in grease zerk, and pick out the inner seals of both bearings before you install them to allow the grease through. That last part is optional in my opinion, I didn't pull the seals out and it worked fine.
 
yea it all made sence once i took the time to think about it .....didnt really need pics
