SSM 52245 2020-2021 Aviator - AWD - Requiring Replacement Of Left Front
Halfshaft Part Number L1MZ-3A427-G - Built On Or Before 20-Aug-2021
Some 2020-2021 Aviator vehicles equipped with all-wheel drive (AWD) built on or before 30-Aug-2021 may
require replacement of the left front halfshaft, part number L1MZ-3A427-G. If the halfshaft is unavailable due to
a part backorder situation, dealers can perform Technical Service Bulletin (TSB) 23-2174. The TSB Service
Procedure uses a revised halfshaft and intermediate shaft, which eliminates the front axle disconnect actuator
assembly and requires an all-wheel-drive (AWD) module software update. Unless the specific TSB criteria are
met, TSB 23-2174 should not be performed if halfshaft part number L1MZ-3A427-G is available.
