Power steering hose noise

Hello all,

First post but I'm sure to be here a long time.

I have a 2006 2500 Duramax and the steering wheel is making a horrible whining noise at certain intervals. What I mean is you can turn it to say, 2:00 I checked everything out and from what I can tell, the power steering hose is the culprit. When you turn the wheel the hose vibrates so fast it goes blurry. If you grab the hose it feels like you are holding a suped up sonic tooth brush! Have any of you heard of such a thing? The steering wheel noise is super annoying and needs to go away now!

Thanks!

I suggest you replace the fluid -- sometimes that corrects a lot of the problems.

The hose is not the problem!

does it sound like it is in the steering wheel???
reason i ask is because if it sounds like it is coming from the steering wheel area it could poosibly be sir coil making noise. they make a whining type noise sometimes when they get a lot of wear on them, only fix is to replace the sir coil.

Thank You. When you are driving it sounds like it is coming right from the steering wheel but you can hear it outside the vehicle as well so...I dont know. I didnt even think about the clockspring since you can hear it outside of the vehicle but it's an easy thing to check out so I will check that next. If it's not that then I will follow JC 1843s advice and replace the power steering fluid. Thanks to all that responded!

I own a collision repair shop and it's amazing how many names there are for parts (sir coil/clockspring). I have a hard time keeping up on all of them!

I did the DIY fluid flush about 5 months ago. It helped the problem but didn't get rid of it.
Whodaman could you explain how to check the clock spring? I know nothing about the steering on these. Thanks!

I'll take it apart on Monday and take some photos so you can see how it is done. Basically there are a few screws on the back side of the steering wheel that need to come off to remove the air bag from the steering wheel. Oh yah, disconnect the battery first! Once the air bag is removed the clock spring is visible. It is round and has a yellow electrical plug on it. Now with some vehicles if you unplug an airbag and then start the car it will set off a code which does not reset itself but has to be reset with a code reader. I don't remember if the Chevy trucks are this way or not but I will check that for you as well since trying to turn the wheel with the power off is a big pain. I'll check it all out Monday and get back to you.

My power steering fluid reservoir is full and the ISS (Intermediate Steering Shaft) has been replaced for those who asked that question.
