*make sure I can remove all the necessary parts first--there's no point in buying the part, and realizing I can't remove a bolt bc it's rusted...
I am worried that I will run into an issue of not being able to figure out how something comes out like others have posted or somehow ruining the ABS sensor (since they're so expensive).
I JUST came here to post about my experience in replacing the hub/bearing assembly. It took me only 2 hours in my driveway with a minimal amount of tools. FYI I have an 04 with 55k miles but I live in a relatively dry area so there wasn't too much corrosion.
First off I ordered the part from AutoPartsWarehouse. I actually ordered a generic hub/bearing that cost only $99! Unfortunately it looks like it's no longer on the site, so the closest is the Timken brand one that's received plenty of good reviews. Came in about a week and it's was ready to be put on the car (ie already lubed up).
I'll do my own step by step that will hopefully help you out.
1. Go to auto store and buy/rent the following (you might have some of this stuff, but I needed them):
a. 32mm axle nut socket (I tried to rent but they were all out so I bought it for ~$15)
b. Replacement cotter pins (I didn't know what size so I just bought a pack that had assorted sizes ~$5)
c. CRC/Freeze out or any sort of rust/corrosion loosener. There is a whole shelf of them, I chose the cheapest. ~$4
2. Other tools you will need: A mechanics set with all of your socket sizes. The sensor is a 10mm, the brake calipers are 17mm I believe, and the 4 bolts for the bearing are something else smaller than the 17mm. Make sure you have some long bolts and an extender. You'll also need some sort of hammer, I used 2lb rubber mallet/hammer type thing, as well as a regular metal claw hammer.
3. Loosen up lug nuts, jack up car, and remove wheel. Once complete, I sprayed all visible bolts with that penetrating liquid. I waited just a couple minutes, sprayed a bit more, the went on to the following step. (2 bolts brake caliper, 4 bolts hub assembly, 1 bolt wheel sensor, and the axle nut)
4. Take the two bolts off from behind and remove the brake caliper from the rotor. I used a small bucket and sat the caliper on top of that. You don't want to let it dangle as it won't reach the ground. Push it as far as you can to the inside of the car to give you room.
5. At this point, nothing is actually holding the brake rotor on the wheel hub assembly. Some light pounding with my rubber hammer got it loose and I slid it right off.
6. Remove cotter pin with a pair of pliers.
7. Remove axle nut. It's nice to have a breaker bar on top of your ratchet to give you more leverage.
8. Remove the ABS wheel sensor from the back of the hub. If you look behind, you'll see the small wire and the 10mm nut. Luckily mine slid right out after removing the bolt. Hopefully you don't run into the corrosion issues like others.
9. Remove the 4 bolts holding the assembly in place. Even with the long extension sockets, I had to turn the wheels left and right to be able to access the top nuts because teh CV boots get in the way. No biggie though.
10. At this point there is nothing hold the assembly in place. You do have to pull it out towards you though as it's teeth are still locked into the axle. It took me about 25 minutes to finally get it out. The techniques I used were banging it from all sides with the rubber hammer. The one that worked the best is hitting it from behind on the right side (passenger side) or left side (driver side). Whatever side is closer to the front of the car because the dust shield on that side isn't in the way and there seems to be more room to swing a hammer. You do bang up the dust shield a bit but don't worry about it. Eventually you'll see it start to separate from the dust shield and just keep pounding away. Like someone else said, you won't be reusing the hub so just go for broke. I hit it so hard one of the lug bolts actually came out. SEriously, I can't stress enough, just keep pounding it, you're breaking all the corrosion and dirt away. I doubt you'll be able to break anything, except the dust shield maybe. You can also try pounding in sideways in a circle, it won't actually spin though because the car is in park, but it should loosen it up that way as well.
11. Once it's out, just slide the new part right back in it's place, line up the holes and put everything back in the order you took it out. Don't forget to put the brake rotor back on I almost forgot. I didn't bother using a torque wrench and everything seems to be fine.
The minute I started driving it was SOOOOOO much more quiet. I'd been driving for about 2 months with that horrible vibration from the front and it's soo smooth now. My car feels brand new. I saved over $200 doing it myself and I highly recommend everyone do it. Let me know if you have any questions.
