9999 MERITOR WABCO ABS VALVE PACKAGE Recall

Campaign:: 01E062000 on 12/18/2001
Component:: Service brakes, air:supply:check valve
Manufactured:: 09/02/2001 - 10/25/2001
Affected:: 21,600
Defect:: Equipment description: meritor wabco pneumatic anitlock brake system (abs) valve packages produced between september 3 and october 26, 2001. the bolts used to assemble steer and drive axle abs valve packages together and a traction control valve inlet fitting were torqued below specification.
Consequence:: Bolts torqued below specification will not reliably prevent air leakage at the affected abs valve package interface joints once the component begins normal vehicle operation. if air leaks develop at any of the abs valve package interface joints, brake system pressure reductions could occur during braking or normal operation with units equipped with the traction control option, potentially extending stopping distances, possibly resulting in a vehicle crash.
Correction:: Owners will be notified to have their vehicle repaired free of charge at an authorized dealer. owner notification began january 14, 2002. owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact meritor wabco at 859-746-5956.
Notes:: Also, customers may contact the national highway traffic safety administration's auto safety hotline at 1-888-dash-2-dot (1-888-327-4236).
