Default BEST front wheel bearing replacement?

One of my front wheel bearings is making noise. Time to replace them both!

http://www.eeuroparts.com/Main/PartD...px?id=4107462S

Is this the best I can buy?
Is this the closest to OEM I can buy? I heard somewhere SKF made the OEM front wheel bearing units for SAABs? Anyways, I will be keeping the car long term and want to buy accordingly. Any other suggestions?

Why replace both? Only one is bad. If one tire is worn unevenly due to, say a bad tie-rod, do you replace both tires? Okay this may not be a good example. But do you always replace bad parts in pairs? Why?

Seeing as when my left front went bad, I replaced both. I would say don't do it.

Why you might ask?

The new right side **** the bed / not very long afterward made the worst grinding noise.

I got to do that side again, at least I saved the reciept, got my money back.

1st side: 6 hours

2nd side: 5 hours

3rd side: 3 hours, slightly different approach

As for items like balljoints, tierod ends control arm bushings, do them in pairs/ all at once. This in my opinion is so you only so you have to get one alignment! (more expensive than the parts anyway)

Shocks in pairs yes, other things maybe not.

Sorry I diverted your question. I don't know the difference. Here is one more diversion. Want to buy a used one cheap? Send me a note.

Search the archive, either here or the SAABnet. I believe I have posted the experience. A few others have too. No big deal. Just unbolt and bolt with the right tools.

I should have been more specific. Im not looking for help on how to install/remove wheel bearings.

I'm looking for help picking the best wheel bearings to purchase. I don't want to end up with a cheap aftermarket wheel bearing that fails earlier than another wheel bearing...

Two very good manufacturers of bearings are Timken and SKF. I have used SKF bearings with classic 900's and would recommend using SKF bearings in a 9000 as well (part number isn't the same between C900 and 9k front bearings though).

Most of the hits I found in Google are for complete front hub replacement and not for actual bearing replacement so you could be better to go along that path. I've read in a few places that the front bearings aren't replacable, but unless someone confirms that, I don't believe it. 8-)

Thank you C900.

That's another good question. Can I buy the bearing itself, or does it have to be the whole hub assembly. I've only found hub assemblies for sale.

Have any of you bought just the 9000 SKF wheel bearing alone?

I do not believe the 9000 front bearing is generic. At least when it fails the two halves of the hub separate and the balls fell out. So it is not pressed in like the c900. I remember having to take the hub of a c900 to a machine shop to have the bearing pressed in way back when.

Just so you know a good brand is not the only thing. If you do not install it properly, meaning if the axle nut is not tightened to spec the bearing will fail prematurely whether it is a reputable brand or an aftermarket.

Interesting point there. I renewed both outer CV boots on my 9k and my torque wrench only goes up to 150 ft/lb so I set it to maximum and used my full body weight standing on it to torque up each axle nut so it's a bit more than 150. It's supposed to be something like 220 though.

OK thank you. I'll have to buy the whole assembly. I'm not sure if I want to replace both of them.

I will probably lump this wheel bearing/hub assembly project together with a large electrical gremlin crackdown campaign, replacing front rotors and pads, and get rid of the junk SAAB MTF0063 or whatever it is tranny fluid I put in.

I'll probably end up buying two. I'm asuming they wore SOMEWHAT evenly, and the other side can't be too far to go...

Resurrecting this thread with a dumb question: how to remove/replace the wheel bearing assembly? There is a 9000 in the local yard I would like to try on.
