Steering System, Checking For Leaks

-- Start the engine.

-- Turn steering wheel in both directions to full lock and hold briefly. This builds up the largest possible pressure (at idle only).

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

• Seal ring for steering pinion at the steering gear valve housing.
• All line connections.
• Seal rings for steering rack.

This test can only be performed with bellows slid back.

-- Open clamp for boot.

-- Push back the boot. If fluid is visible in steering gear housing and/or in bellows, steering gear must be replaced.
