Bearing Packing 101

[warmonger]

FLXX member Benny Davis donated the space necessary to place our tutorial on how to repack the wheel bearings of the Xterra\Frontier\Pathfinder with auto locking hubs. It is located at: http://homepage.mac.com/bennylen/readme.htm
Hopefully you will find this useful! Happy four wheeling!

Looks great! After seeing the water intrusion on those pics I better get mine done.

Hmmm...by looking at the hands in the pictures I say there are a few places to get scraped and cut.

The FLXX Bearing Repacking 101 CD is now released. I have included a photo of the CD and cover. This CD can be run in modern DVD players, IBM and Mac computers. It uses autorun so that it will automatically launch your browser and load up the programming if you have autorun configured. the cost of the CD is $8 plus $2 shipping in the coninental US.

Well, I just did my first bearing packing tonight following warmonger's how-to. All in all pretty good. One thing that made the job kind of nice is that the how-to was written with kind of a "worst case" slant -- meaning it would say you'll have to work hard to loosen this or unseat that but when you actually do it it's not as bad as the how-to makes you think it would be (that was my experience, anyway).

I do have one tip for those who plan to do this: the new bearing seal that has to be "tapped" into place (it's similar to pounding in a paint can lid, or, for the seal removal stage, pounding off a paint can lid) actually started bending at the rim (where i was tapping it) instead of going down into place (yes, I had the seal centered properly); luckily I noticed this quickly and my solution was to cut off the circle of rubber from the OLD bearing seal, place the old seal on top of the new seal (the rubber would have interfered here if it wasn't cut off), and pound on the old seal with the hammer. This method seated the new seal nicely without causing any damage to it.
Oh yah, one more thing: all my bearings looked nice and greasy upon removal *except* the passenger side outer bearing, which was bare to the extent that I could look through the bearing spaces and see clear through to the other side (this gap should be completely filled with grease!). Luckily the bearing showed no damage upon close inspection. I'm certainly glad I decided to get off my duff & do this maintenance job (I waited untill 36K miles, manual says 30K, & I haven't ever had the hubs under water)....
That's all folks & thanks very much Warmonger for the how-to .

Thanks for the compliment. I try to prepare people for a worst case scenario, although it may or may not occur every time. Some people panic when they hit a bad spot unprepared. I am glad I could be of assistance. BTW, if you tap around the seal, it should go in without bending. I have repacked mine three times using this procedure with no problems, but I am also VERY experienced thanks to living in FL and owning three previous 4WD trucks.

Thanks for the update.
I will be trying to re-pack mine in the next few weeks.
I'm guessing that it will be almost the same for manual hubs (I have the Warn ones). Just the removal of the hub will be different.

[warmonger]

Manual hub owners just have more bolts to remove.

... and less parts to take out.

Thanks for the tip...
Do you guys with the warn hubs know where you get the seals for the hubs?
Or if you need new ones after you remove the dial plate?
I have had mine off a few times (trying to fix the bolts with locktight)

Thanks

I'm sure you can get the seals from Warn ... I have removed the dials a few times but haven't needed to replace the seal yet.

Not to mention less to blow apart when you engage the front air locker, eh? ;-)

What about the rear? Is there a set of bearings there too?

[warmonger]

Ben,

There is but they are lubed by the gear lube, no need to manually lubricate them. Just change your gear lube at appropriate intervals and you will be fine.

sweet. next question, how hard is it to do? is it a zirt point? (I think that is what they are called)

Is it possible to check the condition of the bearings without removing any parts that will need to be replaced?

I'm considering repacking the bearings before GoX, but if I don't need it, there are a whole lot of other things on my to-do list.
