The ABS sensor on ALL year Chevy Venture vans is located in the hub on the Left and right front tires. If the sensor is failing you unfortunately have to replace the entire hub. The barrings and the sensor are all sealed inside the hub. The ABS electrical connector is just behind the hub under the CV axle.
The rear ABS sensor should be in the gear box (i can't remember the exact term) in your rear end. The front ABS sensors are in your wheel hubs...
Z71 is an off road performace package.
most common cause is a failed wheel hub causing a worm abs sensor a new sensor should come with the new hub if that is the problem.
