Pre- Alignment Information

WARNING: Do not re-use any fasteners that are worn or deformed in normal use. Many fasteners are designed to be used only once and become unreliable and may fail when used a second time. This includes, but is not limited to, nuts, bolts, washers, self-locking nuts or bolts, circlips, cotter pins. Always follow recommendations given. For replacement always use new parts.


TEST PREREQUISITES

^ Correct calibration of measuring equipment

^ Correct tire pressure (see label on vehicle)

^ Vehicle accurately aligned, suspension bounced and rocked several times

^ Suspension, steering and steering linkage checked 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 start of production a number of vehicles were delivered without an indication of the alignment group number. These vehicles are in group 1.

^ 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 check/adjustments.

^ The actual loaded condition at time of measuring is relative when determining the specifications (empty 1/2 load, full load).

^ If the vehicle alignment stand is approached at an acute angle, then move the vehicle backward and forward several times to relieve possible stress in the bonded rubber mountings.

^ When adjusting, aim as closely as possible to the respective specified value.

^ Only perform vehicle alignment after the vehicle has been driven 1000 to 2000 km (600 to 1200 miles) to ensure the suspension has settled completely.
