2004 f150, flareside. stock tires.

Recently in a parking lot i was making a left turn and had the wheel turned all the way to the left when doing so. Had the windows down and heard a definate rub noise coming from the rear end when doing this. Turned the wheel all the way to the right and it did the same thing. Not loud , but you could hear it. (rub, rub, rub,) If you did not turn the wheel all the way it would not make the noise. Could this be the clutch packs in the rear end, i have Limited Slip and had them replaced once. Trk is under warranty until this November,, should i have dealer look at this or is it normal with LS... thanks.

 

LS do make some noise on turns. Add a bottle of friction modifier then do some figure 8's in a parking lot and see if that helps.
