Wheel Bearing Races?, Do I need outer and inner races for wheel bearing? Options

[dangqiwu]

I bought a Timken front wheel bearing for my 1995 Toyota Celica ST. And I bought inner and outer seals too.
But in the service tech manual I found the outer and inner race, snap ring, and dust deflector. I don't have these on hand.
Someone said the races come with the bearing so that I don't bother to buy more races.

Could anyone clarify this idea? Do I need to buy additional outer and inner races, snap ring, and dust deflector?

Thank you!

You can use the existing snap ring and dust deflector.

I am familiar with the illustration above, have all those parts and am ready to build the assembly.

In the FSM (BGB) there is an installation procedure for putting these parts together. It also installs the lower ball joint in the procedure. It, however, leaves out the installation of the inner and outer oil seals and I am trying to figure out at what point in the assembly process I should install these oil seals.

If I install them right after I install the snap-ring, which is the first time it would be possible to install both, and later install the hub, will installation of the hub do any damage to the oil seals?

Now I have gone through the process (unsatisfactorily, but that's another story) and know more about when (the order in which) the oil seals should be put in place.

You must install the outer oil seal prior to installation of the front axle hub. So, that undocumented step should appear between steps 2 and 3 of the FRONT AXLE HUB ASSEMBLY procedure (SA-17 of the BGB). It also answers my question about whether installation of the hub could damage the oil seal. The answer is that it doesn't matter because you physically cannot install the hub before installing the seal, period. Maybe, you just need to be careful when inserting the spindle of the hub?

You must install the inner oil seal prior to installation of the dust deflector. So, that undocumented step should appear just before step 5 of the FRONT AXLE HUB ASSEMBLY procedure. Installation of the hub, since it is done earlier, cannot effect the inner oil seal and thus cannot do it any damage.

As explained in another comment in this thread, I tried to re-use the dust deflector and proved to myself that Toyota was correct in designating that part as NON-REUSABLE.
