Wheel-bearing question; can you switch out entire hub-assembly?

I'll buy some and hopefully when the Amazon 19mm extractor gets here...it'll work. These kinds of problems are why car-repair is not practical or enjoyable, I don't understand why manufacturers don't apply anti-seize to any prone to fuse-together nut/bolt tbh.

 

I was just about to go spray the nut again with PBblaster. I think the extractor arrives on Thursday. I need to buy an impact wrench so I should look into that. I checked for new wheel-bearings today and as I suspected they cost around $180 (there are lower-tier bearings available but I figure with bearings probably not a good idea to buy the less-expensive).

What BRAND of lubricant is better than WD40, that's the only kind I'm familiar with? Moreover, is there a one-fits-all for both lubricant and penetration (well other than KY)?

thanks.

 

I've always managed to get by without an impact wrench (sooner or later) but I know Milwaukee makes good tools. One thing I don't like about them is how they seem to overtighten everything.

Right now I'm in the "visualizing" phase of removing this 19mm nut. I'm thinking about the PB blaster seeping into every thread of the bolt. Hopefully, when I get the extractor socket my meditations will pay off.

 

thanks.

Sounds like something out of NASA's manufacturing facility. Will look into it.

 

UPDATE:

The PB Blaster worked to get the 19mm nut off of the PartsPrius. It did take some force and started off very slowly but came off soon enough. Thanks for educating me. I'm quite surprised as tend to think these products are simply repackaged existing products such as WD40.

Still havent put the new bearing-assembly on the driverPrius because need to find the time to get that wheel off.

 

UPDATE:

How important is the dust-cover for the front-brake?

Finally, managed to swap the bearings. Very difficult as much had not been likely changed ever and stuck together with rust/corrosion. Rotor was stuck to the wheel and it took me forever to get it off. Then I broke off the head of the speed-sensor 10mm bolt (even though I was very careful). It left a nub for the speed-sensor to sit on which I ended up taping (gorilla tape) to the knuckle. its not very secure.

However I swapped the bearing but don't have a dust-cover for the brake. In my bad-bearing knuckle (which had the only dust-cover available), the bearing fell apart so the bearings were exposed. My partsPrius had the knuckle/good-bearing but no dust-cover. I just swapped it as a temporary fix.

Very difficult to get the bearing-case out without anything to bang on. See pictures below. I might have to get them pressed out and then take that dust-cover and put it on the swapped knuckle with the good bearing which is already installed.

Any ideas about how to get this bearing out of the knuckle without taking it to get pressed-out? My car is fixed and drivable but I'd rather drive with the cover on as it might affect braking in rain/snow/etc.

 

what do you mean longer bolts in the hub? Do you mean use a longer bolt as nail and pound down into it onto the bearing-housing?

only thing I can think of is beating on the bearing-housing from the side but that probably doesn't do much.
