GMC axle venting

This TSB applies to 2003-2010 Chevy Express, 2003-2007 Chevy Silverado Classic, 2007-2010 Chevy Silverado, 2003-2010 GMC Savana, 2003-2007 GMC Sierra Classic, 2007-2010 GMC Sierra and 2003-2010 Hummer H2 vehicles.

Front or rear axle fluid leaks that appear to be coming from the axle vent hose will most often occur during hot ambient temperatures and/or while towing.

Installation of filter P/N 5651682 will act as an accumulator and will prevent fluid from being forced out of the end of the vent tube. Install the filter vertically in either direction, approximately 4 to 6 inches from the end vent cap of the hose or where convenient. Retain the filter using the supplied hose clamps and secure the filter and hose to prevent damage.
