B.
If the steering wheel is off-center, then perform an alignment and road test on the vehicle to confirm the condition is corrected.
2.
Determine if the pulling/drifting to the right is caused by the tires, alignment settings, or the power steering computer.
^
If the tires are non-unidirectional, cross-rotate the left and right front tires.
^
If the tires are unidirectional, then proceed to step 3C (measure and adjust the vehicle alignment to within specifications).
3.
Perform a road test on the vehicle to determine if the direction of pull has changed.
A.
If the vehicle pull/drift is eliminated, then the probable cause is tire conicity, and the repair is completed.
B.
If the pull/drift has reversed (i.e., now pulls to the left), then refer to TSB No. ST004-01, "Repair Manual Supplement: Vehicle Pulling to
One Side."
C.
If the tire rotation did NOT change the pulling/drifting condition, then measure and adjust the vehicle alignment to within specifications.
D.
Increase right front camber and decrease left front camber.
NOTE:
^
Do NOT exceed 1° of cross camber.
^
Do NOT exceed adjustment specification range.
E.
If the vehicle still exhibits a pull/drift to the right after performing the alignment, then replace the power steering computer assembly (P/N
89650-48010).
For removal and installation of the power steering computer assembly, refer to the Technical Information System (TIS), 2006 model year
