Can someone please explain how to install the hubs/wheel bearings for a 2000 Oldsmobile Alero? Thanks for any help. I appreciate it.

if it's not addressed by tomorrow i'll bust out the camera and walk you through it with pics... although i won't rip mine off casue they can be a pain... off hand i'd say rent a hub puller from the local tool rental shop... makes life a lot easier... although it can be done without one... unless they are froze on real bad.

[alerored04]

slide hammer is very helpful as well.

and a metal bar to give your ratchet's extra leverage... unless you are lucky and own a set of impacts

Kinda old thread.. But I just had to replace my passenger side front wheel hub bearing. On the aleros you cant just repack the bearings like you can with some cars and trucks. Go to advance or auto zone and ask for the part. Make sure it has the ABS on it. (They should give you the right one.)

1. Jack the car up.

2. Put jack stands under it. ( if you dont know which side is bad, put your ebrake on and accelerate slowly up to about 35MPH.. then just listen and you will be able to tell which side it is.)

3. Take the wheel off

4. Take your brake calipers off

5. Take your hub nut off. ( ? part name )

6. Use a rubber mallat to beat off the rotor.

7. There are 4 other bolts that hold the hub on. You can locate them behind the rotor.

8. Put replacement hub bearing on and make sure you plug in the ABS.

9. Put everything back together.

Pretty easy fix. The part is 110 bucks tho.

Hub nut size is 1 3/8" deep, 3/4" drive. Get it before you begin, and loosen it before jacking up the car (it just makes it easier)

Only 3 bolts held my hub on. - You may have to tap the driveshaft out of the hub with a mallet.

Impacts FTW Took 20 minutes each in front.

Impacts would make a huge difference...

Hey guys, I plan on knocking htis out tomorow, my question is how much easier does a hub puller make the job?

[sound_xtreme]

mine was still stock. neither of my impacts would take that center nut off. dunno how the shop did, but i ended up takin mine to one. bolts were just too rusted/corroded to get off

lol well the it looks liek i am in for4 a good time. It's a 99 and with the original hubs.

I had to replace my girlfriend's front and rear hub. thanks for the information guys. it was greatly appreciated. A couple of notes or lessons learned though; the left rear; don't forget to take off the emergency brake. It had to take off two screws in order to take off the hub. Also, use a hammer to take off the hub. This should work. As for the front, it was seized in there for life. I tried everything. I took the hammer to it because, I did not have a torche to un-seize it. I even bought a puller; no go. In the end, the hub came apart in four pieces and I had to pry it out with a flat screw driver. Careful not to damage the sleeve. It took the day to take it out and 20 minutes to put it back together. Go figure. By the way, I used an impact for everything except the top bolt (one of the three). works wonders.

i finally got around to replacing my wheel bearing today and there is lock-tite all over the 3 screws and they're the tightest screws ive ever had to deal with anyways i got all but 1 out because its stripped im just waiting for my uncle to come over with a torch

[Gr1m]

how did you strip it? were you using a swivel or not?

[Vinman]

you know its funny you ask if he used a swivel..if you look at a haynes manual, it says to use one....god i hate that manual...

[Gr1m]

thats why i asked..you wouldnt strip it if you used one.
