On vehicles built before the Chassis End No's. above, complaints of a loud humming noise or vibrations at highway speeds, as well as leaks at the rear
transmission cover or cracked exhaust pipes could have been caused by a centering sleeve with insufficient grease in the front drive shaft. In this case,
the bronze bushing located in the centering sleeve must be checked. The procedure for checking this bushing is outlined in the attached W.I. #191.
