While performing the transfer case clutch shimming procedure found in Service Information (SI), you may find it necessary to replace the clutch pack selective fit shim to obtain the correct clutch pack clearance.
The selective fit shims for this repair were previously released as a kit, P/N 12474121, which contained all eight selective fit sizes. Effective immediately, the clutch pack shims will be available individually as listed below. The shim kit, P/N 12474121, will be discontinued and no longer available once current stock has been depleted.
