New Old Stock (NOS) — Unused part in original condition. Packaging may show age-related shelf wear. Original ACL packaging present but in heavily soiled condition — significant moisture staining, surface mould/mildew marks, corner crushing and delamination to outer cardboard box. Bearings themselves remain in original factory poly wrapping (clear and yellow), appear uninstalled and unhandled. Internal condition of bearings not verifiable without unwrapping but factory seals appear intact. Rubber and elastomer components such as belts, seals, and gaskets may harden or degrade during extended storage — inspect before fitting. Please confirm this part number suits your vehicle before purchasing.
