Chevrolet Dealer Service Bulletin 88-290-4C is being revised to provide a part number for a new front axle vent plug assembly. All copies of 88-290-4C
dated July, 1988, should be discarded.
Some owners of 1988 K trucks may comment on front axle leaks through the remote axle vent. A new front axle vent plug assembly, part number
26015413, will be used in 1989 K models. The new vent plug assembly will have a "weather vane" inside to prevent direct flow of axle fluid into the
vent. The new part can be installed on 1988 K models to correct front axle leaks through the remote vent.
