The Meritor 1229C991 is a genuine Meritor washer sold in a 4-pack, designed for use in Meritor differential assemblies. Washers like this are a standard rebuild component, used as seating surfaces, load-distribution pieces, or thrust spacers within the differential. Having the correct OEM part number is critical when sourcing hardware for a differential rebuild, as dimensional tolerances on these pieces directly affect bearing preload and gear alignment.
