To check, install the steering knuckle 1 on the gauge 2 A.96008, clamped in a vice so that its surface under the wheel hub seal coincides with the gauge hole. Insert the two side mounting pins of the gauge into the knuckle holes. If inserting the pins requires some effort, the knuckle is deformed and must be replaced with a new one.
