-- The Measuring Square VAS 241001 -1- must lie against the bottom of the trailing arm -2- in direction of -arrows-.
-- The distance measurement between the Measuring Square VAS 241001 and the trailing arm must only take place on the surface -1- of the test area -2-.
-- Adjust the Gauge - Gap Adjustment 3371 -3- to a thickness of 2.25 mm (blue and white plates together).
-- Measure the distance between the trailing arm -2- and the Measuring Square VAS 241001 -1- with the Gauge - Gap Adjustment 3371 -3- in the test area.
Measures distance -a- Between the Measuring Square VAS 241001 -1- and the Trailing Arm -2- is Larger than 2.25 mm:
The permitted tolerance range is exceeded. The axle beam must be replaced. Refer to AXLE BEAM .
Measures Distance -a- Between the Measuring Square VAS 241001 -1- and the Trailing Arm -2- is Smaller than 2.25 mm:
The permitted tolerance range has not been exceeded. The trailing arm on the axle beam is OK.
