Preliminary Alignment Inspection
Important:
-
Check and set the alignment with a full fuel tank.
-
Jounce the vehicle three times before checking the alignment to eliminate false readings.
-
Check the rear and the front suspension dimensions according to Trim Height Specifications in Suspension Diagnosis.
-
Set the toe left side and set the toe right side separately per wheel. Set the steering wheel angle at 0 degrees ± 3.5 degrees.
-
Cross caster within 0.75 degrees.
-
Slot the strut tower.
-
Cross camber within 0.75 degrees.
Loose and/or worn suspension parts will prevent an accurate setting of the alignment angles.
