Steering: Testing and Inspection

Steering System, Checking for Leaks

• Following installation operations and with no hydraulic fluid in the reservoir, the steering system must be checked for leaks.

- Start 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 gear.

This test can only be performed with boots slid back.

- Open hose clamps for boots.

- Slide back boots. If fluid is visible in steering gear housing and/or in boots, steering gear must be replaced.
