Detailed Description

Standard ALS2637T is an ABS wheel speed sensor engineered for rear left placement on select Chevrolet Impala and Chevrolet Malibu applications. It uses a rectangular female connector, 2 terminals, and a bolt-mount design to match the factory-style sensor layout. The 51.5-inch harness supports routing from the wheel area to the vehicle connection point, and the part is listed as an OE replacement for direct service on the specified GM fitments. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Sensor Can Address

• ABS warning light caused by a failed rear wheel speed signal
• Traction control or stability system faults tied to wheel speed input
• Intermittent braking system alerts from a damaged sensor harness
• Loss of accurate wheel speed data at the rear left wheel
• Diagnostic trouble codes related to ABS sensor performance

Installation Notes and Tips

Confirm rear left placement before installation and compare the connector, terminal style, and harness routing to the original sensor. Inspect the wheel-end mounting point and wiring path for corrosion, abrasion, or debris before installing ALS2637T. Because mounting hardware is not included, reuse or source the correct factory-style fastener as needed. Verify the connector locks fully and clear any stored ABS codes after installation.
