Help keep your differential turning smoothly and its gears properly supported with the National Axle Differential Bearing A-36 (also written A36). It fits many vehicles, among them the 1983-2021 Ford F-150, 1999-2018 Chevrolet Silverado 1500 and 1986-1998 Ford Mustang, as a direct-fit replacement for the listed applications.
This National bearing is cataloged under several names: Axle Differential Bearing, Automatic Transmission Differential Bearing and Automatic Transmission Pinion Bearing. Differential and pinion bearings support the rotating differential case and pinion so the gears can mesh as designed and turn with low friction.
Signs that a differential or pinion bearing may need replacing include a whine, growl or rumble that changes with vehicle speed, and roughness or play in the rotating assembly. Diagnose the cause before replacing, since other driveline parts can make similar noises. If a worn bearing is the cause, this National part replaces it. The Buyer's Guide tab lists every vehicle this bearing fits.
