• Description:

  This is the genuine Ford differential carrier bearing shim for the Ford 9.75-inch rear axle, a precision-ground selective spacer that sets carrier bearing preload and ring-and-pinion backlash during axle assembly or gear service. It is part of base 4067, a graduated thickness family stepped in roughly five-thousandths-of-an-inch increments so the correct total shim stack can be dialed in to specification; this particular suffix is the .275-inch thickness. It is cataloged for F-150 and related light trucks using the 9.75-inch rear axle across a long production span, and the same shim series carries into Expedition and Navigator applications that share the axle. Using the wrong shim thickness leaves incorrect preload or backlash, which shows up as a driveline whine that changes with load, premature carrier bearing wear, or gear noise after a rebuild. This is an internal axle setup component and is definitely not a shock absorber, spring, or suspension part. Select the exact thickness against the shop manual bearing-preload and backlash targets, and always set it with a fresh ring gear and pinion measurement rather than reusing an assumed value.
