Replacing the hose is a relatively easy DIY job and inexpensive repair.

Power Steering Moans or Whines During Cold Start-Up
- Service Bulletin 07-060
A moan or whine is heard when turning the steering wheel when the engine is cold. There may be air bubbles or foam in the power steering reservoir.
The noise usually goes away when the engine warms up. Air is entering the power steering pump through the inlet joint O-ring.
This causes bubbles to form in the power steering fluid, leading to reduced pump performance.
TL Power Steering Feed Hose Leak
- Service Bulletin 08-016
Prolonged high under-hood temperatures may cause the power steering hose to deteriorate prematurely and may cause the hose to crack and leak power steering fluid.
Power steering fluid leaking onto a hot catalytic converter will generate smoke and could lead to an under-hood fire.
