So I replaced my bearing hub on both sizes on my 01 ZR2. They fit well, and I plugged the ABS sensors in and went for a test drive. First stop was OK. Next stop, the ABS kept engaging and I almost rolled thru a stop sign. After that, the ABS and "BRAKE!" dummy lights came on and have stayed on since. Then I went to see what was going on this weekend, pulled the tires and rotors and saw the following:


It's almost like the back edge of the rotor sawed this off as it spun around. But I don't think there's an incorrect way to install this hub assy. Anybody experience this before, or have any ideas where I could find a lower profile ABS sensor? The base on this sensor just seems too long. By looking at where it is cut, you can see that it's about 1/4" away from the inflexible base, so I can't bend it out of the way anymore.



<-- I don't know.

 

Damn! That doesn't look right... All of the other hub assemblies I have installed on the later model 2nd gens had a bolt on ABS sensor and the wiring went out at a right angle through that hole, not straight out towards the rotor...

You've found the problem though.

What was the part number for the hubs you installed? Where did you get them from?

 

I just replaced my passenger front one and it was as Swarlkk described and held in place with a single allen head bolt.

 

Hmm....I dunno. Here's the sales confirmation I got from hub-bearing.com

"Vehicle:2001, CHEVROLET, BLAZER S10/T10, V6-262ci 4.3L F/I Vi
2Axle Bearing And Hub Assembly
front ; 4wd ; 2 Per Veh ; Base;hub Bearing ; Years:2000-2001;PARTS PLUS BEARINGS & SEALS 513124 ".

The hub was a direct fit. I'm gonna give them a call tomorrow to see WTF is going on. As much as I dislike ABS in Buffalo snow, I dislike a dash full of dummy lights even more!

 

That is the proper PN for the timken part (as well as a few other knock offs). Looks like they gave you a knock off brand that is NOT a direct fit.

Here is an image showing what it should look like in this area:

 

When I changed mine they were also right angle with 1 allen bolt. Mine came from the big O.

Alright, thanks for the responses guys. I think I'll get ahold of cust-service and see what their policy is on making their customers happy.

Thanks!
