Problem... When I turn I hear grinding. Thought it was the traction control but no faults found. Thinking it might have something to due with the rod mods, because I hear it more in offroad mode while turning..

They can't see any issue? Any ideas?

 

you mean the grinding from hitting the bump stops. otherwise put some grease on the bump stops on the front.

 

Usually this sound is from the rear diff if you have locking diff, LSD... you'll get an odd grinding/roar sound. Have they checked, do you have a locking diff?

 

I don't think I have the rear diff. But I would hear that in the front wheel areas?

 

Wheel bearings?

 

Can you feel the car bump when you hear the noise?

 

i have similar problem for a wile.I replace tire and noise is gone.
You may need rotate tire for a start.
