i just had my boxed in subframe installed. after a couple days it started creaking pretty badly. could this be happening if they did not pre load the control arms before they torqued them down? i had it done by a reliable shop but i dont think they have ever worked on a contour before. choices in idaho are pretty limited. any other possible causes? all they did was install the subframe and switch the eibachs for H&R's. It sounds just as bad as it did when the subframe was broken. help.
