1991 EXPLORER
ISSUE:
A comprehensive, pull and drift diagnostic procedure has been developed to assist techicians with truck service.
ACTION:
Use the following service procedure to resolve drift and pull concerns.
This is the same basic procedure as published in TSB 90-7-16 for the 1988-90 Bronco and F-150, 4x4 models. However, you should note that there are
some differences such as replacing radius arm bushings instead of installing a radius arm bracket kit, etc.
Proceed with the Pull and Drift Diagnostic Procedure if the pull or drift is not significantly reduced or where there is a case of steady state drift (no
braking).
A Diagnostic Check List has been provided at the end of this article to use with this procedure.
NOTE:
THIS TSB ARTICLE SHOULD BE READ COMPLETELY BEFORE PERFORMING DIAGNOSTICS OR REPAIRS.
