CERTIFICATIONS

I, Phyllis E. Cochran, certify that:

    1.  I have reviewed this quarterly report on Form 10-Q of Navistar Financial  Corporation,
        subsidiary of International Truck and Engine Corporation;

    2.  Based on my  knowledge,  this  report  does not  contain  any  untrue  statement  of a
        material fact or omit to state a material fact necessary to make the statements  made,
        in light of the  circumstances  under which such  statements were made, not misleading
        with respect to the period covered by this report;

    3.  Based on my  knowledge,  the financial  statements,  and other  financial  information
        included  in this  report,  fairly  present in all  material  respects  the  financial
        condition,  results of operations and cash flows of the registrant as of, and for, the
        periods presented in this report;

    4.  The registrant's  other certifying  officer and I are responsible for establishing and
        maintaining  disclosure  controls  and  procedures  (as defined in Exchange  Act Rules
        13a-15(e) and 15d-15(e)) for the registrant and have:

           a)  Designed such  disclosure  controls and  procedures,  or caused such disclosure
               controls and  procedures to be designed under our  supervision,  to ensure that
               material  information  relating to the registrant,  including its  consolidated
               subsidiaries,   is  made  known  to  us  by  others   within  those   entities,
               particularly during the period in which this report is being prepared;

           b)  Evaluated  the  effectiveness  of  the  registrant's  disclosure  controls  and
               procedures   and   presented   in  this  report  our   conclusions   about  the
               effectiveness of the disclosure  controls and procedures,  as of the end of the
               period covered by this report based on such evaluation; and

           c)  Disclosed in this report any change in the  registrant's  internal control over
               financial  reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f))
               that  occurred  during  the  registrant's   most  recent  fiscal  quarter  (the
               registrant's  fourth fiscal  quarter in the case of an annual  report) that has
               materially  affected,  or  is  reasonably  likely  to  materially  affect,  the
               registrant's internal control over financial reporting; and

    5.  The  registrant's  other  certifying  officer and I have disclosed,  based on our most
        recent  evaluation of internal control over financial  reporting,  to the registrant's
        auditors  and the audit  committee  of  registrant's  board of  directors  (or persons
        performing the equivalent functions):

           a)  All  significant   deficiencies  and  material  weaknesses  in  the  design  or
               operation of internal  control over  financial  reporting  which are reasonably
               likely to  adversely  affect  the  registrant's  ability  to  record,  process,
               summarize and report information; and

           b)  Any  fraud,  whether  or  not  material,  that  involves  management  or  other
               employees who have a significant  role in the  registrant's  internal  controls
               over financial reporting.
