Another (simple) wheel bearing question

So wheel bearings are apparently a grey zone with these trucks.... I have an 07' 4x4 and it's either chinese crap or the most expensive ones you can find.

Rockauto does however sell the complete prerunner bearings(made by SKF) for the same price as complete chinese 4WD bearings

I want to put my 4WD hubs into prerunner bearing assmblies

Once I take my 4WD bearings off, can I also remove the prerunner hubs from the new bearings, and install my hubs to convert them? Or are the bearings totally different? A lot of stuff seems to say theyre the same other than the hubs. Or do tacoma hubs not come out nicely and become scrap?

Rockauto shows the actual bearing itself seems to be universal for all models
"Front; 4WD; RWD; Base Model; Pre Runner" so the only difference should be the hub, right?

I've never replaced these bearings yet, also my first tacoma too. If I can spend $130/side and push my hub in without chinese parts, im ok with that. Then this gives me bearing cores to push new bearings in and keep ready for next time.

Is this a viable plan or am I missing something?

 

Why are you trying to put the 4wd hubs into the prerunner brearings?

FYI a 4wd hub assembly NEEDS the outer CV cup to hold the assembly together.

 

This

The axle nut does more than hold the axle into the hub.
It holds the bearing together at the correct preload too.

 

Big differences, you need specific hubs.

The CV nut holds the bearing together from the outside.

2WD models are held together from the inside.

Once a hub is installed on a bearing, the bearing cannot be reused again with another hub.

EDIT: The bearing is the same, but I would never reuse it after removing the hub.

 

Once I remove a hub, it doesn’t get used again. None of it.
Because I don’t have a press, and it’s not worth it to me. I buy new.

As a Tech, what are your thought on actually replacing the bearings?
It seems time consuming to me? Dealer here wants $700 a side. And they don’t sell a whole assembly.
Just the bearings, individually.

 

We had a deal with a shop.

They would bring me 5 hub/bearings and I would charge 1.0 for the 1st and 0.5 for each one after. I usually did 5-6 for them.

On the truck I think its 2.5 so roughly 400+ parts.

I encourage people to remove them and bring them to a shop. Takes us a lot less time.

 

who the hell taught you this? the hub just pushes right out, its not a matched set. And yes I know its held together on the other side than the 2WD, that shouldnt change anything.


So basically no one here has a clue, at all lmao

 

you never answered the question as to WHY you are trying to do what you are asking.


when @Bishop84 said "Once a hub is installed on a bearing, the bearing cannot be reused again with another hub." its because once pressed on completely there is no way to "unpress" the bearing seated closest to the flange properly (by pushing on the inner race)

 

^^^ This....

When pressing OUT the hub from the bearing in causes undue pressure on the rollers of the bearing. This can cause a dimple on the race which will cause premature failure of the bearing itself. If you have a 2wd vehicle (Pre-runner model, not 5 lugger) then the best thing you can do to save money is buy a bearing and new seal and get a shop to press out your old hub and press it into a new bearing.

 

What you two are saying makes absolutely no sense. This would also apply when they press the hub in at the factory also, it would "cause undue pressure on the rollers". Seriously, who taught you guys this nonsense? What happens when you press your own hub in at home? You destroy one of the bearings? what the hell?

The reason why is plainly stated in the first post, but I guess people here have absolutely no god damn comprehension. Is this just a "what tires fit my stock lift" forum or what?

All i'm hoping to find out, is that aside from the HUB, is the REST OF THE BEARING, the SAME BETWEEN A PRERUNNER AND A 4WD

You guys not knowing how bearings come apart or how to use a press isn't part of my question

 

I think what they are referring to is the inner race of the bearings is 2 piece and there's no way to keep the outer half from popping out when you press the hub out because of the press fit on the hub which can damage the bearing.
There's also typically no way to get that part off the hub without cutting a slot in it and driving it off with a chisel.

Not a Tacoma hub but this is what I'm talking about.

 

Dude first off, when you are asking for peoples input, you don't have to be rude about it if you can't understand the reply you are getting. People take their time to answer your question, the LEAST you can do is be polite. I'll try to break it down to you in a way that can be easier to understand.

When you are pressing a hub INTO the bearing assemble, you place a die tool onto the inner race on the inner section of the bearing. (The part that is opposite the hub being pressed in) So when the hub is being pressed in, the hub itself is pushing on the inner race on the outer side (the side the hub goes into). What this means is that all of the force of the press is going directly from the hub to the two races, and to the die. The way you know there is no pressure on the rollers themselves is that while pressing in the hub, you can actually turn the bearing case unit. So no force is being applied to the rollers or the race.

Now when you are going to press the hub OUT on the bearing, you have no place for a die to go. You have to use a puller. This puller grasps the outside of the cage, because you can't reach the inner race where the hub is located. Because of this, all of the force being used to push the hub itself out is being transferred directly to the rollers and the race in the bearing. This can result in potential damage. Thus the reason you never reuse the bearing itself. Usually what happens is the bearing is pulled apart and the inner race is left behind (as seen in the above photo) Once this is done, you do NOT want to just try and put it all together and press in a hub again.

Hopefully that explains things better for you. No need to be rude. I promise you I have many more years experience doing this than you.

Take a look at this video from ADV4X4 that shows you more details.

Some of the smartest guys on this forum are in here trying to help you. But you're flipping out at them. Facebook might be a better fit for you

 

Its obvious that you dont know how to properly press a bearing on..... so at this point. Good luck in your endeavors.

 

Your question was answered.

To have given you the answer you actually needed, we would have need more information. For instance, you needed to tell us if you were or were not going to reuse the bearings.

FWIW, I looked up the outer bearing/hub/Bering module.
The part # was the same. Everything else needs To be changed. (Even the bearings, all of them)

 

Try it on a press and see if it "pushes right out". Before that even happens, make sure you have the correct SST tool to loosen the big spanner nut on the back of the PreRunner bearing.

By the way, SKF makes a 4x4 bearing-hub assy too, P/N BR930978. Out of stock at Rock Auto, but I'm sure you're mature enough to look for it from another site https://www.rockauto.com/en/moreinfo.php?pk=12676781&cc=1431544&pt=1636&jsn=428

 

Dude just joined the site and has a great attitude.

 

Nice. Thanks my guy I added an alert for these.
