9	Select new adjusting plates (3) on the basis of the removed adjusting plates (3) and the camber deviation determined in the initial measurement	Check suspension data, assign actual value to table Model 205.386/387 with code 835 (South Korea version)	AR40.20-P-0001-01LWX
		Check suspension data, assign actual value to table Model 205.386/387/486/487 except code 835 (South Korea version) The new adjusting plates (3) to be installed must be determined on the basis of the measured camber deviation and the adjusting plates (3) already installed using the suspension data table. All the adjusting plates (3) of one spring link (1) must have the same number.	AR40.20-P-0001-01LWW
10	Install newly determined adjusting plates (3) and tighten nut of screw (2)	Tighten the nut of the screw (2) in ready-to-drive condition in order to rule out stresses in the spring link (1). Make sure that the adjusting plates (3) are seated correctly and in the correct installation position. The screwdriver bit is to be used when a screw (2) with a multi-point socket is installed. Only tighten the nut of the screw (2) to the 1st stage of the specified tightening torque.
