What radio are you using? Sounds like a neutral resolution problem to me.

ill try and see if any shims/washers would even fit, if not, i can use some electrical tape. as funny as it sounds, ive used electrical tape on some jobs and it holds up great hahah.
ill just poke the hinge pins through the tape. ill report back when the results.
im using a old fm radio. it had no problems with my other vechicles with it though. what do i do to check the neutral resolution? i tried the steering trim, sub trim, and the epa

nope that wasnt the problem. i tried putting the washer front and back and didnt work.
i wanna say its the tires that is doing all this cus when i have the truck in the air, and give it throttle, my truck shakes a pretty good amount. so theyre pretty unbalanced. but someone said they have had some bad unbalanced tires in their days, and he never had this problem.
oh well, i guess ill have to live with this. thanks to everybody that contributed any help. i really do apppreciate the great tips and info, maybe it will help somebody else down the line.
BUT if you guys happen to think of something else, please post back on here.
