The sensor uses a bolt-mount configuration and an octagon connector shape, with a female connector and male mini-blade terminals to match the vehicle-side connection style. The integrated 33-inch harness helps route the sensor lead from the wheel area to the connection point without unnecessary splicing.\u003c\/p\u003e\u003cp\u003eThis part cross-references Monroe Shocks \u0026amp; Struts (e.g., 172286, 182286) for the same application. When replacing a failed ABS sensor, ALS3663 provides a direct-fit service option for the rear right position on Silverado 3500 HD and Sierra 3500 HD trucks, and the part number ALS3663 is a useful reference during catalog lookup and verification.\u003c\/p\u003e\u003ch2\u003eWhat This Sensor Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eABS warning light caused by a faulty rear wheel speed signal\u003c\/li\u003e\n\u003cli\u003eIntermittent wheel speed data at the rear right wheel\u003c\/li\u003e\n\u003cli\u003eBrake system fault codes related to wheel speed sensor input\u003c\/li\u003e\n\u003cli\u003eLoss of ABS function from damaged sensor wiring or connector issues\u003c\/li\u003e\n\u003cli\u003eReplacement needs after corrosion, impact, or harness wear at the wheel end\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify rear right fitment before installation on 2020-2024 Chevrolet Silverado 3500 HD and 2020-2024 GMC Sierra 3500 HD models. Inspect the mounting surface, connector condition, and harness routing path before securing the sensor with the bolt-mount design.
