STEERING

Navistar, Inc. (Navistar) is recalling certain 2016 International DuraStar, LoneStar, ProStar, TerraStar, TranStar, WorkStar, 9900i, and IC Bus HC vehicles equipped with certain Spicer D or E series steer axles. The castellated nut on the steer axles may not be properly torqued, allowing the tie rod to loosen.

Risk: If the tie rod loosens, it may disconnect from the steering knuckle, causing a complete loss of steering, increasing the risk of a crash.

EQUIPMENT

Navistar, Inc. (Navistar) is recalling certain 2000-2001 International 4700, 2000-2002 4900, 2001-2003 8100 (TranStar) and 9100I, 2002-2003, 2005, 2007-2009, 2012-2014 and 2016-2018 DuraStar, 2012 and 2014-2017 ProStar, 2014-2015 TerraStar, and 2018 LT trucks. These vehicles are equipped with Kidde Plastic-Handle or Push Button 'Pindicator' fire extinguishers that may become clogged, preventing the extinguisher from discharging as expected or excessive force may be needed to activate the extinguisher. Additionally, in certain models, the nozzle may detach from the valve assembly with enough force that it could cause injury and also render the product inoperable.
