CAUTION:

If a steering gear assembly is returned under warranty with leaking rack bar seals, but there is also damage to the steering gear boot/boots (refer to Component Tests in this section for guidance on how to check for steering gear boot damage: COMPONENT TESTS ), then the steering gear warranty will be invalid. This is due to the steering gear rack bar seals being damaged due to foreign materials entering the steering gear boot and damaging the steering gear rack bar seals thereafter
If a steering gear assembly is returned under warranty with leaking rack bar seals, induced by abusive steering loads, the steering gear warranty will be invalid. Guidance on identification of abusive loads via tie-rod inspection can be found in the Tie-Rod Checks in Section 211-03 - Steering Linkage/Diagnosis and Testing/Steering Linkage/Component Tests
