slight grinding on one side after 5100 install

Did this on a friends truck what could it be?
Stock springs, 2011 dbl cab trd 4x4, 5100's set at 1.75

Any thoughts?

Do the springs need to "face" a certain way? I wouldnt think so but a google search mentioned this somewhere..

Thanks guys

 

Pictures would help, I lowered my Mazda and after I lowered it I had grinding noises and it ended up being warped rotors, it could be shit fallen off your rotors and is stuck in the pad too. Give it some time see how it is then.

Maybe get a sound clip of it aswell

I did post this slightly prematurely. I havent actually heard the "grinding" or what it could be. Ill report back once I see my friend again.

 

Stock tires?
