I think this is a scenario where the right, or maybe different, tools came in handy for me and made the bearing removal/installation go like butter.
As I was changing the backing plates, I needed to reuse the bearings, so a slide hammer was absolutely out of the question.
Thankfully I have an air compressor and an air hammer, so i was able to push the axle shaft back with the pointed air chisel attachment, which fits perfect in the center of the threaded portion of the axle shaft.
And then the flat hammer attachment was used on 4 longer bolts that i threaded into the bearing assembly from the back, after removing the original 4 bolts.
And considering my IS was 5 years old in a salt environment (it is Canada after all), I can't believe they came out so easily.
I was prepared for a fight going in, and i don't think I even broke a sweat.

 

Hey fellas, after I remove the wheel and brake caliper, I shouldn't have to remove the E-Brake assembly right? Also the axle nut size is 32MM? Hopefully I do not need to remove the nut. Some videos I watched, the guys never removed the axle nut or the E-brake assembly.

 

it is either 30 or 32mm one. I bought both at Home depot, and later returned one after trying both... unfortunately I do not remember what was the size of the socket that I had decided to keep.

I think the only way you do not have to remove a nut is gonna be the front wheel on RWD... I doubt you can remove the axle without removing that hub nut first. There is a reason that nut is installed there and it is not for the looks.

 

Thanks bro!!

 

Axle nut definitely has to come off. remember when you put it back on, the torque on it is pretty heavy. I don't know for sure but likely between 160-210 lb ft. Look it up. i'm sure you know by now but there's a little nub that folds over (likely two) that you have to chisel out to remove the nut. or you can force the nut off with air tools which should undo those tabs. i recommend using a brand new nut to reinstall

as far as e brake... hard to say without being there. can you post a pic?

 

yeah, I think you are correct on the torque numbers. And no, at least on my IS 2015, e-brake assembly did not have to be removed.

 

Okay thanks for the info. I was asking about the ebrake because I seen 1 guy on Youtube take it off but have also seen other not take it off. I guess what I am asking is, is it possible to remove the wheel bearing hub without removing the ebrake? I do not have a pic as of now. My cousin and I plan on changing out my wheel bearing hub this weekend depending on the shipping from rockauto.

 

Make sure you remove the Abs sensor, before trying to pull out the axle.. or you will break it.
and when you are assembling it, stick a big screwdriver in its place, so that opening stays...open )
Another point to make is - make sure you put that metal ring with a hole for the sensor correctly, before making everything tight.

 

The E-Brake components can stay in place...you should be able to slide out the entire assembly without disturbing any of the e-brake components. It's likely fairly close to everything, but will clear.

 

Thanks Sasnuke!!! Well today is the day I will install my new hub assembly. My cousin and I will install it. I will go to rent the 12 point 32MM socket for the axle nut and probably just go ahead and buy a new axle nut just in case. So pretty much these are the steps and correct me if I am wrong...

1. Remove wheel
2. Remove brake pads and caliper
3. Disconnect ABS sensor
4. Remove rotor
5. Remove 32MM axle nut and the 4 10MM nuts that hold the existing hub assembly in place
6. Do I tap in the axle to free the hub assembly??? I am confused at this point and forgive me but if so that when I install the new one, do I pull the axle back so the the new hub assembly will fit correctly???
7. Torque axle nut and hub assembly bolts to spec
8. Reinstall brake caliper, brake pads, etc
9. Reinstall wheel

Are these the correct steps? Please feel free to correct me if I am wrong as I do not feel comfortable with Step 6

Thanks again guys and I appreciate all the help, advice and patience with me thus far!!!

 

1. Remove wheel
2. Un-stake axle nut
3. Apply Parking Brake, step on Brakes, and then remove axle nut
4. Release Parking Brake and regular brakes
5. Remove caliper (14mm or 12mm bolts hold the caliper onto the bracket) and brake pads
6. Remove caliper bracket (should be 2x17mm bolts)
7. Disconnect ABS sensor (I think a 10mm bolt holds this in...not 100% sure)
8. Remove rotor (may need to back off Parking Brake adjuster...through the rubber grommet in the rotor)
9. Remove 4x17MM nuts that hold the existing hub assembly in place
10. Tap axle backwards through hub...this is only to free up the axle from the hub, it will not go very far...you just want to make sure they are not stuck together
11. Remove wheel bearing assembly
12. Install new wheel bearing assembly...be sure to slide axle into the assembly as you install it...torque the bolts down
13. Go to Step 8...install the rotor, then work your way up to Step 1, putting everything back

 

Here's the official instructions. You'll see that they want you to remove the entire knuckle off the car to change the bearing.
If there is similar space behind the knuckle like the front, then you can do it on the car, like the front.
I suggest reading through the instructions before you attempt it in case you have any other questions.

 

How can I tell if my bearing has gone bad? My front wheels are making a lot of noise and I'm not sure if it's just my tires or my bearings. I only have 73k kms on a 2014 IS350 F Sport so I'd be surprised if the bearing is already gone.
