Condition
Some customers may comment on a low volume hiss and/or rush noise heard from the steering column area. The noise may change when the steering
wheel is rotated in either direction. The noise may be noticeable with the engine ON, vehicle in PARK, HVAC and Radio OFF.
Cause
The lower steering column intermediate shaft may be internally grounding out, creating a noise path.
Diagnosis and Correction
To determine if the lower intermediate shaft is allowing noise to travel from the power steering hydraulic system into the vehicle passenger compartment,
follow the steps below.
