Steering/Suspension - Pull Or Drift Concern
NUMBER CHA 033GROUP Chassis
DATE July, 2011
MODEL Sorento (XM)
SUBJECT: SUB-FRAME AND SUSPENSION ADJUSTMENT FOR DRIFT CONCERN
This bulletin provides information related to a drift condition and adjusting/settling the suspension components under load as assembly variation can remain on the suspension. Camber and Caster may need slight adjustment depending on actual road conditions. To improve this condition the dealer is requested to first follow the TSB CHA 032 (Drift/Pull Diagnosis and Best Practices Tips) for specifications and if they are outside the parameters then perform the instructions as directed in this TSB.
NOTICE
Before performing this TSB, the dealer alignment machine must be calibrated and updated with the latest software available. Failure to use the proper specifications will result in incorrect alignment settings and a customer return.
Lifting device as shown must be used to load suspension components, if the suspension components are left to hang as with a 2 post lift this procedure will not help in resolving the concern.
The method behind this procedure is to compensate for loaded or twisted suspension bushings and sub-frame position which can occur during normal build variation.
Tire rotation and wheel alignment should have been performed within the 12 months/12,000 miles before using this TSB. Vehicles outside the initial 12/12 adjustment period will require DPSM authorization.
