- Remove the front, center and rear noise insulation.

In this position, the following components must be checked for leaks.

• All line connections.

• Hydraulic oil cooler.

• Seal ring for steering pinion at the steering gear valve housing.

• Seal rings for steering rack.

This test can only be performed with bellows slid back.

If fluid is visible in steering gear housing and/or in bellows, steering gear must be replaced.
