Review on ACDelco 19181873 Original Equipment Sensor by Bomba Ton

Fits and works. Doesn't come with pucks. Doesn't explain if he needs pads or doesn't need pads. A little hint as to whether it is a revised part would be nice. Unfortunately, you can guess that. Your application may differ if you use OEM wheel hubs or OEM constant shafts. Small differences in production and tooling can mean the difference between luck, headaches or big cash outlays. If you are installing this and using existing spacers you may need to disassemble everything to remove the spacers. If you install it and don't use gaskets you risk damaging the sensor. Or maybe your project will get a visit from a lucky fairy and everything will go smoothly!
