Power Steering Noise/Vibration

Recently I've notice that my power steering pump seems to be loud. And I can sometimes feel a vibration in the petals, mostly when turning the wheel. Is this normal?

Not dumb at all because, NO I didn't...however I did bring it to the dealer this past week for an oil change...figured they'd check, but I shouldn't figure anything. If it's low at 15,000 there's a problem. I will check it, thanks.

I can't help with the noise but the vibration sounds like the classic "intermediate steering shaft" problem. My '04 gasser had it and now my '06 Dmax does too. (with just 15K) Kind of pi$$es me off that GM didn't fix it before now. Make sure you have the dealer check the shaft while they have it. Good luck.

Say wasn't there something about a valve between the steering and brakes that could malfunction and actually cause the brakes to be applied when the wheel was turned?

I recall reading that the DuraMax uses the same pump for power brakes and steering, and if they cross feed through the valve - bad things happen.

I don't think I would wait too long for a trip to the dealer.

Does this problem occour during parking lot type manuvers??????? If so there is a TSB that states to r&r the pressure control valve in the PS pump. It's fixed all the ones I've seen w/ the shudder during slow speed turning.
