I have. Looked into this sooo much.. It's crazy...I have changed out the back new drums then turned them and new shoes and front as well even new calipers. But they continue to warp I say within a yrs time. I'm just thinking that this truck hard on them. But it seems when are you leaving? I first got this truck I did have any issue at all with them, until that first change over....I even went to ceramic instead of the semi metallic. I have posted this on this forum before and still I haven't figured it out. But I won't be getting the slotted ones just the solid ones. As far as the rotors I one got ones from napa, but started out with autozone.
