On certain 540I, 540IA, 740IA, 740ILA and 750ILA, the differential pinion shaft in the differential case assembly was not properly surface hardened. This condition will result in premature wear which can lead to noisy operation and ultimately to a lack of drive capability through the rear axle. Correction: Entire differential assembly will be replace on affected vehicles.
