rear hub-inner race

simple quick question about replacing the rear hub...i got the write ups on the procedures and everything im ok with that.... im stuck on the inner race part..not on how to remove it but I wanna know is there a new inner race already installed in the new bearing or is that a separate piece that needs to be bought? thanks in advance

Bearings have an inner and outer race between which the balls are sandwiched. The inner is the steel jacket forming the bearing's inner bore. Because it's typically press-fit onto something (the flange) it gets mangled and "peels" off with the hub flange when you remove the bearing from the flange with a puller or splitter or other methods. It's not a "part" per se, more like metal scrap that's in the way and has to be removed before you can install a new bearing on the flange.

ok cool.. i didn't wanna be stuck at that junction...thanks a lot for your response..

I explained the whole thing in the REAR bearing DIY:

yes your DIY is what i've been reading and looking over many many times..lol im sure i'll look it over again before i actually do it.. but i just wanted to be sure on the inner race part.. but seems all is clear now guess its more studying before the final..

Look at the drawing carefully as if you are an engineer, then it will be clear to you that the hub is mated to the INNER race, which consists of 2 separate parts (1a and 1b) in the photo.
The "1b" part comes out with the hub. This "1b" part needs to be removed.

When you get the new bearing, look at it, the only thing that prevents the Inner race from falling out is the seal! The inner lip of the seal hugs around the Inner Race, preventing it from falling off.

Once installed, the force of the Axle Nut will clamp the hub against the Inner Race then against the very edge of the half-shaft. It is like a sandwich.

I will give you a multiple-choice exam later to make sure you know the stuff lol.

PM me your cell number and time/date you plan to do it. This way if you run into problems, you can call me for online help.

Here is my epic journey of changing e rear wheel bearings.

Fronts took an hour, rear took a whole day each they were so stuck.
