On 2004 AWD ABS, does the rear bearing hub have ABS???

[Android]

This is driving me crazy, has postponed my repair numerous times. On the 2004 AWD Vibe with ABS, does the rear bearing hub have ABS??? Is there an ABS line leading there to connect to a sensor, or is the ABS just in the front wheels? I've been able to find everything BUT a rear hub for AWD (requiring a drive shaft to enter the middle) and an ABS sensor connector. I've tried NAPA, Carquest, AutoZone, Advance, and a couple of independent parts stores. I'd HATE to get this at a Pontiac or Toyota dealership, having to pay 4 or more times more than needed.

Here's an example. I'll try the online RockAuto site, but all the others show pretty much the same. From...
http://www.rockauto.com/catalog/raframecatalog.php" onclick="window.open(this.href);return false;
TIMKEN Part # HA590002 Ball Bearing; 3.927 in. Bolt Circle Diam; 5.315 in. Flange Diameter; 2.182 in. Flange Offset; Modified Flange Shape; 54.03 mm Wheel Pilot Diam - Rear; 4-Wheel ABS; AWD; XR Model
Here's a photo of this hub...

and has the text "Features a pre-sealed, pre-greased and pre-set bearing package design with integrated sensing technology for anti-lock braking systems, total traction control and vehicle dynamics systems."

Now tell me, looking at that photo, where does the sensor wire plug in to? This appears to be just a plain drive hub/bearing assembly. What am I missing here. Am I crazy or are the parts stores leading me astray? Or is this really just a part sold by the dealer? Yes one more store, Pep Boys, actually did the diagnosis for me for free, pulling the tires telling me the grinding noise is my left-rear wheel bearing failing. But they said they couldn't do the work, didn't have the right hub in stock or at their warehouse, and said I needed to go to a dealer to get the part.

Please respond ASAP, as I need to go on a long trip soon (about 600 miles round trip) and would like to get this repaired. If I drive the VIbe anyway, what's the worst that can happen? Can the wheel seize up?

Now I'm not sure if it has ABS on the rear but it does have a "ABS" wheel speed sensor that is used for the TPMS. Basically if one tire is spiinning more than the others, for some period of time, it must be low on air. It then trips the Tire Pressure sensor on the dash.

Oh by the way these cars are 4WD not AWD. Pontiac didn't badge them right and that's why they are out of business....

It has a sensor that's in the hub? Really I don't care about ABS, I know how to emergency brake myself, but I want the car to be "legal" on the road. What about the rear hub? Does it need/have an ABS sensor if my 2004 Vibe is "ABS" ??? Or does the ABS sensor, that you see on non-drive-train hubs, such as here, only exists on the rear wheels in the FWD model?

If the rear AWD hubs need an ABS sensor, then I can't find it anywhere at any of the parts stores. Can someone please respond who's familiar with this?

BTW, I called attention to this to the RockAuto site, and they took down all references to the rear hub having ABS in AWD Vibes. I was able to find the image I linked to in my last response by querying the Toyota Matrix, which I think RockAuto hasn't yet made the connection on their website.

RockAuto responded to my email. Their response...
"Thank you for your email. I checked with manufacturer and the technician at Timken confirmed that this vehicle has a tone ring around the axle that is hooked up to the sensor. This is why the hub assembly doesn't have sensor connection on it."

So does this mean I don't have to mess with ABS/non-ABS on the AWD Pontiac Vibe rear hub? This was driving me crazy trying to find an ABS AWD rear hub. So this isn't a dealer-only part? Please let me know ASAP as I want to get this thing fixed.

the 2wd rear hub assembly has the connector on the back of the bearing assembly for abs (if equipped). these will not have provisions for an axle to pass through.

the awd rear hub assembly will not have any provisions for an abs sensor, only provisions for the axle to pass through. the sensor is separate from the hub assembly and is mounted the the knuckle, the tone ring is part of the rear axle assembly.

Thanks bluneon. That seems to reflect what RockAuto said, and what I've observed thus far.

So now I think I have the right hub replacement, but I don't know how to get the big nut off of the rear AWD hub. Seems to have some sort of key engaged. I'll try to upload a pic or two, maybe make this a new topic. And the smaller bolts holding the hub on in the back seem to be totally inaccessible. The shaft/axle seems to be in the way. Maybe if I get the big nut off, the shaft will come out of the way allowing me to gain access to the smaller bolts. If anyone has done this job before, replacing the rear hub of an AWD Vibe/Matrix, please offer some suggestions.

[bluneon]

the axle nut is not reusable once removed, this is because the nut is staked to the threads of the axle end. to remove the nut you'll need to unstake the nut and use a special socket to remove the nut. you must unstake the nut fully, otherwise you'll severely gouge the threads of the axle. you'll need to replace the axle if this happens.

after you remove the nut you can push the axle end in to make extra room to gain access to the rear bolts holding the hub assembly to the knuckle. then remove the hub assembly. reinstall with a new nut and stake it to the axle shaft.

I had the hub replaced but now just got around to replacing a sensor connected to the hub. I continued my question in this post...
