Default 2010 wrx rear wheel bearing removal problem

Hello,

WhileI was using a puller to remove the rear wheel bearing the bearing hub split apart and now the back half remains attached to the car with the emergency brake andback plate. How do I know remove theback part of the wheel bearing hub?

Did you take the bolts out of the knuckle?

remove the bolts holding the bearing housing to the knuckle (4 of them on the back side around the axle).
the ebrake plate will likely still be attached, youll have to pound out the bearing using a mallet or sledge.

Are you saying that the wheel hub split in half? I don't think that is what you are saying, is it?

Are you saying that the wheel bearing split in half, so that when you pulled the hub off the car, 1/2 of the bearing came out with the hub, and 1/2 the bearing is still sitting in the knuckle? This is what I think you are saying

What you need is this kit:

Pretty simple to use.
Here is a good video on it:

Wheel Bearing Removal with Harbor Freight Universal Tool BMW 3 Series Rear Front - YouTube

he has a 2010 wrx, which has bolt on bearing assemblies. you do not need any special tools to remove them other than removing the bolts and pounding them out with a hammer (due to rust build up). they are not press fit at all.

i've replaced all 4 of the bearing assemblies on my own 2010 wrx so i know how this goes. that kit is not applicable to his car.

Completely understood.

Since all he has to do is pull the wheel hub, which can be done with a puller or a slide hammer, all that is left is the four (4) bolts holding the bearing assembly to the knuckle.

Time for the OP to post a picture of what the issue is so we can see. Hubs are pretty strong so I would be surprised if it actually split/broke as the OP is saying.

You don't pull the hub. The whole bearing and hub come as an assembly.

Which is what I realized after the last post. The "newer" models come that way, not so on our "older" models.

But, also why I said to post a picture of what the issue is so we can see what the OP is saying. Just doesn't make sense as described

Sounds to me like the OP took the wrong approach. Tried to pull the hub out as if it was an older car.

So he pulled the hub out of the bearing assembly and the bearing assembly is still bolted to the car.

He needs to unbolt it and just replace the whole thing.

Exactly. That is what it is sounding like but we will probably never know as the OP probably won't be back

Okay, this just happened to me too.<br />
I removed the four 14m bolts from the back and sprayed penatrating oil on it while using a slide hammer with hub puller attachment. Now I have half a bearing on my puller and the other half in my car frozen solid -_- wtff

PS idk how to post pic or I would

For bolt in hub bearing assemblies my trick as follows: I have an air chisel hammer bit that has brass pucks on the end. I back out the bolts leaving the bolts threaded in at least halfway. Hammer away with the brass bit against the bolt heads and 99.9% of assemblies work right out of the knuckle. I have a 2 lb. brass hammer to knock the assembly out of the backing plate once the assembly is out of the knuckle.

Take one of your bolts, match thread pitch and get a longer bolt or two, so you don't risk damaging the factory ones. Then go to town with your blunt force instrument of choice.
