Weird steering issue

[D3UC3S]

I have a weird noise coming from the front when turning up an incline/decline only. Straight driving, no issues, flat turning surface, no problems. I just had new tires put on thursday, but I don't believe its a rubbing issue since it justa started today. Anyone have any ideas??? I know my info is vague, but I really don't have any other way to describe it. You can feel in in the seat too if that helps.

I looked under the truck and all the steering components look straight. No bolts/nuts backing out, everything seems tight.

check your lug nuts?

I ck'd them, they are all good

Ck'd hubs, they were good. Jacked each side with the wheel maxed in each direction, spun the wheels fwd and aft. They were fine, no rubbing. Greased all the zerks up front, a lot of the steering linkage joints were dry. Had my wife turn the wheel lock to lock, pull out and in to the INCLINED driveway from both directions. Could not duplicate the problem. I highly doubt the grease fixed it. You can feel it when it happens in the seat. Im confused

New tires have a certain roughness I think....I can always feel that when I get a new set of all terrains or luggier tires.

More specific now.

Only makes the noise when turning right, and comes from left front when suspension is being compressed. I'm thinking maybe left front hub bearings are going. Only making the noise when more weight is being transferred to that side when turning right. Its definatley rotational.

Opinions???

Jack that side up and see what's going on!!

Read post#4...already did. Everything seems tight and spins fine...I might just replace the bearings since its cheap and easy to do. At least for the piece of mind.

Selective reading I guess. Any rub marks on bumper or leaf springs? Pull the wheel off and look at the brake rotor and caliper, then you can service the bearings while you're there.
