Greetings, my name is Mark.

As you can see below, I have included some "flow-chart" basic checks for your wheel speed sensors. You will need a DVOM. (Digital Volt Ohm Meter)

It's not a bad idea to check and follow the chart for the readings. However, I have replaced literally dozens of front hubs and unfortunately, your vehicle is known for this.

One thing you might do, especially if your vehicle is high mileage. Unhook the front sensor and then peel the the tape and wrapping back about 4-5 inches. (NOT the sensor side, the vehicle side) Carefully tug on the wires. If you can do it individually, that would be better. Sometimes the wire will break inside the insulation and a visual inspection is not enough. If you can easily break the wire, you can buy a lead that you will solder in.

From the turning of the wheel back-n-forth, the wire inside will break. It's not very common, but I have run across it.

No doubt though, you will probably end up replacing your front hub & bearings. There is only a couple manufacturers of these hubs, so NAPA is just as good as OEM.

Below the "flow-chart" diagnostics, I have included the repair procedure. You'll find when you get the bolts out of the bearing, it will be seized in the knuckle. You will need a pretty good size hammer to beat it out. The Sensor may stay in the knuckle and you can pry it out with a big screwdriver.

Clean the knuckle real good with some sandpaper or wire brush.

If you need anything else, let me know.
Thanks, XXXXX XXXXX
