Binding, noise, no assist to either or both sides, vibration,
leakage or poor returnability.
Contamination from defective components or hoses is blocking
fluid flow.
When replacing any steering component it is recommended that
power steering lines be replaced if older than 4 years or appear
damaged. Also the entire system must be flushed with new fluid
to wash away any contaminates.
If you do not flush the system and replace lines you could
experience a return of the symptoms noted above. Failure to
properly service the power steering system will VOID THE
WARRANTY.
Some manufacturers even recommend an annual change of the power
steering fluid to increase the longevity of the system.
