The Pinion Washer from GMC Acadia locks in the precise amount of torque on the steering and differential shafts. This provides daily drivers with confident control. This hard metal ring sits between the pinion nut and flange, distributing clamp force so that gear teeth remain in alignment, lubricant remains sealed, and heat stays low. The Pinion Washer safeguards against vibration that causes early wear since every Acadia built from 2007 through 2022 relies on sharp rack and pinion motion. There are two factory versions, one for the front assembly and another for the rear differential. Furthermore, GMC specs provide the Pinion Washer's inner diameter and thickness, so owners just match the location and torque for perfect fitment. Correct installation of the Pinion Washer will ensure smooth transmission of steering commands, unhindered ABS and airbags, and maintaining the safety record of the SUV. The pinion seal and differential cover work in conjunction to seal gear oil, preventing spills that can scorch moving gears. This enhances the performance efficiency of the drivetrain and improves the longevity of components on SL, SLE, SLT, AT4, and Denali trims of the Acadia. This factory part requires no special maintenance, but it continues to strengthen the Acadia's robust feel, whether the vehicle is carrying five passengers or a full load of seven. The hardened steel make, which offers anti-corrosive properties, and the chamfered edges, which ensure easy installation, are features that make the Pinion Washer stand out. GMC tests conducted with discipline demonstrate that the clamp load is still within spec after thousands of cycles. This is proof of legacy. Every GMC parts catalog lists the Pinion Washer as a critical wear item; however, not every Acadia owner ever replaces it as it is made to last. This GMC part has been a long time coming for both generations of Acadia. The Pinion Washer is proof of why a dependable part matters.
