Hello,
I am having a very frustrating issue with my steering system. When I drive for a good bit and turn my steering wheel it is making a grinding noise. The noise is also happening when I am parked as well. If my truck has been sitting around for a couple of hours the issue does not happen until I drive for more than 5-10 mins. I have checked my steering fluid and its up to spec. Whenever I turn there is no vibration in the steering wheel and there is no wear on my tires either. I took it to the shop and they were not able to recreate issue.

I was wondering if it could be an issue with tie rod ends/ball joints wearing or my steering wheel pump.

Any help would be greatly appreciated.

It may be an issue with the power steering pump. It may need to be flushed or replaced. This is just a suggestion, not a diagnosis. I encourage you to consult with a certified technician.

Please keep us posted.

Has anyone ever had a complaint about the steering column having an issue? Is there a bearing or shim that goes bad?

 

I just talked to a service center and they said that it is most likely the Intermediate Steering Shaft. The bearings are probably bad. Louis do you think that could be a possibility?

 

The're probably not bad but just dry...I'd be my guess that they replace the shaft with a upgraded one if that is indeed the problem...
Search the forum for the intermediate shaft and there are several threads on the subject...

 

new to me...never heard of an intermediate shaft grind all I've ran into is clunks

I suppose it's possible the steering column seal needs to be replaced. Sometimes it can be difficult to diagnose problems by description alone. The fact that this is an intermittent issue has me puzzled. I suggest having your tech take a look.

Keep us posted.

Welcome to the forum.

Not sure the NBS even has an intermediate shaft like the previous model did.

 

I got the same issue
It is exactly as you discribe it.
It drives me nuts.
Any ideas how to fix this

 

Oh, it does. And the one in my '07 grinds at times, clunks at others. This is another problem that GM is well aware of--I think there's a TSB on it--and it's common in a number of models over a number of years. But if you're out of warranty, the cost is on you. The estimate on mine was $350, but my extended warranty should cover all but $100 (the part itself is about $60 from gmpartsonline.com). The current version supposedly uses teflon and never needs grease--but I've seen reports of problems with that one as well.
