Location of ABS Sensors

Does anyone know where the ABS Sensors are on a 99 Jeep Grand Cherokee? Please dont tell me that they are attached to the wheel hub and in order to replace you have to buy the whole unit...thanks!

The parts book I looked at shows, you only replace the sensor, if that is the problem, not the hub unit. Pull the tire, look for electrical wiring in the brake area, that should lead to the sensor.

You can go to the parts store, ask to see an ABS sensor, for your vehicle. That way you'll know what it looks like. Just tell them you want to look at it, you don't have to buy it.
