Ah HA!
I swapped out my differential gears for 410s around the same time too, cuz they were going out and howling like crazy.
Well, that's gotta be where my problem was.
I guess we solved my abs... but that doesn't fix much, unless you got a bad rear end too.

 

It's not necessarily a bad rear end. There is a notched ring that the sensor magnetically senses. If that isn't reinstalled, this could cause your problems. And yes it is possible to put your rear axle back together with out that ring.

 

thanks for all the good info guys i was havin the same prob with abs inop light comin on and no cruise im gunna check into new sensors at work. Im a ast. mgr. at advance auto parts. hince the name.

 

I have the same problem with my Camaro but I have never lost use of my brakes. So far so good, I guess I have been lucky.
