my 04 S seems to have a front right bearing that has gone bad. I have used the excellent nam picture/word how tos in the past (brakes, oil change, etc.) and hope there is one for this. Is there??

 

You'll need to have a pneumatic air gun and a 1 1/4 inch or 32mm socket. The torque on the axle nut is a crazy 134ftlbs.

I had to have to work done at a shop because I have no pneumatic tools. The process would have been easy enough though.

You'll have to unbolt the caliper, remove the rotor, unbolt the axle nut, and then undo 4 bolts on the backside of the steering knuckle that go into the hub assembly. It should then come out.

Line up the splines and put the new one in. I don't think there is a specific orientation to it.

I'm not sure on all the torque values for the 4 hub bolts or caliper, but the torx that holds the rotor on is 20ftlbs and the axle nut is 134ftlbs. I can check my Bentley manual for more details when I get back home.

 

To, perhaps, fill in some blanks....

According to the factory and Haynes the bearing/hub assembly is a sealed unit. You'll need to replace the entire hub. Some have claimed that anything can be rebuilt and I suppose this is true. But if you want to find a parts list, what you need is a hub. The good news is that the hub is a pretty straight forward replacement.

The steps above are almost it - just add removing the wheel speed sensor from the hub carrier after you remove the brake and b4 you remove the 4 bolts holding the hub (according to Haynes)

You can also find all needed torque specs there (costs less then the Bentley...sort of a Chevy )

 

thanks guys--I guess I'll give it a go. hub at advanced auto is $195.00. Does this seem about right?

 

I spent $250 for a new wheel bearing from the dealer. The place I had it installed quoted me $300 for the bearing and $80 for installation. I got the part on my own and came back for the install. I didn't try looking at autoparts stores because I didn't want a sub-standard part.

 

omg i just sheared the torx bolt holding the rotor!!

 

A pneumatic wrench is not necessary to remove the axle nut, just loosen it with a long flex handle while the tire is still on the ground. When finished, torque it to 134 after the tire is back on the ground.

The wheel speed sensor does not need to be removed, at least on an 06. Just be gentle when pulling it out.

YD

 

I am about to do this work the my car going to change the two front hubs. Sounds like fun to me. lol...

 

Sorry to bring a old thread back to life (curse me for using the search tool) if I had a brand new wheel bearing with hub assembly how hard is it to replace? If it really is just $80 bucks to get it done at a shop, I might just take it to a mechanic.

 

When you are replaceing the wheel hubs make sure you get a quality hub.

There are many "asian" aftermarket hubs being sold. Stay away from them. They will not last.

The "Hub" is a precision unit. I'm not sure who the OEM hub is mfg. by. I have found that SKF has the MINI hubs available. They are more expensive, $185.00 each, but they are worth it.

Remember:
Quality prevents **** poor performance.

 

anybody know the torque values for the 4 bolts on the back of the hub unit?

 

What're the trusted OEM brands out there for front wheel hubs? I made a mistake last year of going cheaper and paying the price already - one of those hubs is done as the bearing went bad. Thanks.

 

We carry the OEM MINI and OES wheel bearing here, I have replaced mine with Febi in the past.

These are R50 R52 R53 production up to 7/2006 front wheel bearings. We also carry the kits to do both sides with hardware. Sometimes those bolts on the back can be pretty rusted.

Here is a link where the torque values were talked about.

Thanks

 

edit: got a little post happy there lol. Ended up getting a hold of live chat and they were able to get me the parts I was looking for. Thanks again for the info and suggestions.

 

You are welcome. Just saw this post, looks like everything is gtg. Thanks

 

I put Crap Amazon hubs on. I can feel the slop in them a year later. Buy quality.

 

Just got the new bearing on yesterday and boy is it nice to hear the road again and no more bearing grind. First time changing one, so it took a couple hours to work my way through it, but it was not terrible.

After getting everything back together, I now have the ABS/DSC/Tire pressure lights on when the car is on... Do I just need to reset these with the tire pressure button below the handbrake? or does it sound like a broke a sensor wire? I was pretty careful with the caliper unit and the wires connecting to it, and didn't disconnect any wires in the process.

 

Sounds like you bumped or broke the head of the ABS sensor. Also try re-pluging the ABS sensor into the plug socket, did you unplug it ?

Thanks for the response, that is what i figured. I didn't unplug any wires, left everything where it was. I saw the head of the sensor in there when I pulled the old hub off, and it looked fine. I didn't mess with it, and just put the new hub on and got everything back together. If they are as fragile as it sounds, then I probably bumped the head of the sensor and broke it.
