dont really know where to put this. have a 2500 2006 silverado 4x4 truck for the last 5 years. have lost 1 of the center caps. the fake nuts loosen up and the caps get loose. when i see a loose nut i just pushed it back in. didnt know they had threads on them. no flat tires to change in that time. get them rotated at service station. seemed like they just started coming loose all of a sudden. anyone know how to fix this problem? thought about using something like a drop or 2 of locktite on the threads. just wonder if i could take them off without busting them. i put this on TrucksByNet.com but hasnt had much activey. thanks
