Operation CHARM: Car repair manuals for everyone.

Preliminary Requirements


Requirements
- Measuring equipment correctly adjusted
- Tires inflated to correct pressure
- Vehicle accurately aligned, suspension bounced and rocked several times
- Suspension, steering and steering linkage check for excessive play and damage.
- Vehicle height (ride height) to specification

NOTE:
^ The specifications for vehicle alignment are divided into four groups. The group to which a vehicle is assigned is indicated on the vehicle data plate on the A-pillar at the height of the central electric box, refer to Vehicle Group Number, Position On Data Plate.
^ Vehicle height (ride height) and vehicle longitudinal inclination affect test values. For this reason, measure vehicle height and longitudinal inclination, and adjust vehicle height if necessary before performing checks/adjustments.
Refer to: Front Ride Height Measurement. Testing and Inspection
Refer to: Longitudinal Inclination Measurement. Testing and Inspection
^ Loaded condition at time of measuring is relative when determining specifications (unladen, 112 payload, fully laden).
^ If alignment machine is approached at an acute angle, move vehicle back and forth several times to relieve possible stress in bonded rubber mounts.
^ Align vehicle after accumulating 1000 to 2000 km (600 to 1200 miles); only then will settlings be complete and stable.
