I have a 1991 caprice and I want to know the cause of this continous rattling noise while driving on a mildly ridged road. It's highly annoying. I replaced upper lower ball joints, sway bar link kit, shocks were severely worn, and brake pads, anything that could have a little play while driving...
prior to this, it would have very few signal bars wherever i went and the sim reader is a little dodgy... is the internal antenna busted, do i need a new phone?
