So I tested each of the sensors with a meter while having my kids spin the wheels. Passenger side I got over 400 ACmV's but driver's side would only read 210 ACmV's. Checked a few times and definitely a lower reading on that side spinning wheels as equally as we could. So I got a new AC Delco wheel speed sensor and put it on the driver's side tonight. No dice! I know I need to pull the wheel again and check with meter.
My question is if I get the lower reading again with the meter is it possible something is wrong inside the hub? I understand the sensor reads rings or a magnet of some sort inside the hub. Could that be the issue? Or how do I rule out the ABS Module or Brain itself? I have heard that is an expensive fix! Any help diagnosing is appreciated.
There is nothing really to go wrong inside a bearing. Short of obvious physical damage. As I said in my previous post, don't rule out a defective part. The last Delco sensor I put in lasted a year like yours and then started putting out too low of a voltage. In my case a replacement fixed it.
If there is no ABS light on and no codes stored, there more than likely isn't an issue with the unit. This is the only problem that won't set a code- and that's only because the ABS module doesn't see a circuit problem during it's self check and thinks that a wheel is locking.
If you're looking at replacing a bearing assembly, DO NOT CHEAP OUT! Timken or SKF would be my first choice. BCA a distant second.
