On 675 Freightliner 1999 model year trucks and more than 1,500 Internationals made in January and equipped with Meritor automatic slack adjusters, the automatic slack adjusters had insufficient torque applied to the guide pawl cap screw. The brakes could gradually lose adjustment. Dealers will check the torque on the automatic slack adjuster guide pawl. If there is no torque, the brakes will be adjusted and the guide pawl will be tightened to 15-20 lbs.-ft. Owner notification is expected to begin this month for Freightliner owners and was supposed to begin last month for International owners.
More than 4,000 Navistar International heavy-duty trucks manufactured March 1998 - October 1998 have a problem with the steering axle. On certain truck chassis equipped with 16,000-pound, 18,000-pound, or 20,000-pound heavy duty steering axles, the inner wheel bearing cone for the steering axle wheel hub assembly does not properly fit onto the Navistar steering axle spindle assembly. This increases the stress levels to the steering axle spindle, which could cause spindle failure and loss of control. Dealers will remove the left and right hub/drum assemblies from the steering axles and replace the inner wheel bearing cones and cups. Owner notification was to begin last month.
Owners who do not receive the free remedy within a reasonable time should contact Freightliner at 1-800-547-0712 or Navistar at 1-800-448-7825.
