Had anyone faced a noise in front suspension ?

After 5K Miles on my NBS, a noise like some rubber something is dry and creak noise is comming, only noise , nothing is felt during the noise. it is in the right front wheel side, it is getting worse, started after a 1K trip I made and everytime I drive for a long distince it becoms louder.

I toke it to the delaer once bt the noise didn't came out there!!! 2 days later it came back and till today.

anyone knows what is this?

pardon me my ignorance, but what is NBS? new bought silverado?
is it 4x4 or rear drive only?
you have rubber(polyurethane) bushings in control arms, shock absorber, also, tierod ends and ball joints can make noise if they run dry on grease or boots are torn and dirt got inside. if you have paralellogram steering, there are ball joints in pitman, idler, and trailing rod.
that's about the rubber parts in suspension. if it's suspension and not something else.
tirewell cover might rub on something. i'd jack the front end securily and scope for any possible contacts/signs of rubbing/loose pieces. you might have something cought underneath, i had a guy driving in front of me on freeway with bag of a sort cought on suspension, some noise it must have making.

Motor mount, sway bar bushing, spring pad, or body mount donut? But, those are obvious, it's probably going to be something devious like a mislocated radiator isolator.

Is it louder around corners?

Thanks for your explaination , and it is 4x4,
(NBS = New Body Style ,GM trucks Sierra & Silverado)

Will a very good cleaning and greasing will do the work ? it is a new car and the production in 07 Nov so can it be that the rubbers dried that bad that I need to replace them ?

Thanks

What does your owners manual say?
Are there zerk fittings at the usual lube points?
Of course, I'm not implying that a dealer could, or ever would, pass along bad info.
