I've looked through the service manuals and haven't been able to find anything.

 

Your wheel bearings are sealed, there is nothing to lubricate.

 

So only the 4wd's have sealed wheel bearings front and rear?

 

I was told by a parts guy about 6 months back that you will probably never run into the proper tool to lube them with. And it is really expensive apparently.

Just what I was told. If a bearing take a shit then replace it.

Yes you have to replace them, and you will know when they are going out... It sounds like a little squeak every once in a while at first. Then it just turns into a weird vibration type noise that just will get louder and louder.
It has happened to both of mine.
Make sure you go to someone you trust to get them pressed. The first one I had repaired, I took to someone I didnt know, and it went out in less than a year.

And no, they dont have races you just pop out.

 

Front wheel bearings aren't sealed. Push outwards in the middle of races and they pop out.

 

you are correct, but to get to the races, you have to press out the hub.

 

I'd still consider them sealed as the outer race and bearing cup employee a seal... the inner seam where it splits apart wouldn't be that vunerable to the elements that I could see...

Sure you could repack them...

But unless one has a shop press at home... I would suggest running them until they go to shit and then just pressing in new ones...

Otherwise if one is paying to have them pressed... then it wouldn't be cost effective to pull them just to grease them... as they may not hold up much longer if they already have a shit load of miles and offroad stresses on them

And if the seals are in place... they should not lose any grease... Nor get contaminated...

If a seal failed... then most likely... they've already been damaged...

 

That's the point, they incorporate a seal. I have been in the parts business for 21 years, I know the true definition of a "sealed bearing". Sure they CAN be taken apart but they are not designed to. Any tapered roller bearing that incorporates a seal between the inner and outer race is a "sealed" bearing.

 

Quit being a dick, we can see what's in the pics you provided. What does the warning (on the seal) say in the second pic? Look at a new bearing, it should have a seal on both sides..Ooo and by the way, you can carry on an adult conversation without the smart ass remarks..

 

I wasn't going to say anything else, but you should have capitolized the D in Dick.
The bearing doesn't have a seal only a retainer holding the inners inside the outer race.
My new bearings only had a light film of what looked like white lithium grease so I popped them apart and packed w/wheel bearing grease. Are they serviceable maybe, is it practical I don't think so and as for smart ass remarks how about FUCK YOU!

 

The bearing is a non serviceable item. When assembled in the hub it is a sealed unit.

There is a seal that is pressed into the open side that seals the bearing to the hub.

The bearing should NEVER be reused once pressed out of the hub assembly. It will likely be damaged by the dissasembly process.

 

Thank you Gadget..

 

Kinda---but special means expensive! lol I dont know how much they cost, but older pickup 4wd rear wheel bearings cost 90 a piece at my dealer.

 

Well...Lets get spun up a bit why don't we..We (Gadget and I specifically) are just trying to share some facts on the parts design so others will know how you are supposed to handle them. I'm sorry you take such offense to voices of experience, so carry on...Ooo and that "retainer" is also called the "seal" even though it's not what most think of as one. Have a nice day.

 

I'm not spun up or offended by the voices of experience, in fact I would appreciate it if you or Gadget would be kind enough to post up some more information on sealed taper roller bearings. Like specific applications as well as the manufacturers, cost of such bearings verses non sealed taper roller bearings, and a simple explanation of why the radial taper roller bearings(like our trucks utilize) also require a inner and outer oil seal to protect the sealed bearings.

I know that sounds like a lot, but with 21yrs experience it shouldn't take to long.
Thanks in advance.
