When I get around 60 mph my truck starts to shake but either I think it might be the ball joints or just unbalanced tires. What do you guys think?

 

I would say your tires. Im having the same problem but I think mine is a mix of tires and unblances driveshaft. I replaced the slip yoke end of my driveshaft because it was beat all to hell so I know thats one reason it vibrates and I got my tires balanced and he said the front 2 were chopped real bad because some didnt rotate them so your def going to get vibration from them but it is alil better now that there in the back and I dont feel em as strong in the steering wheel and making my damn glovebox rattle like crazy ha. I still havent got my driveshaft balanced because the only shop around cant get it done it a short time. this is my DD and they said theere way to busy to even do it in like 3 days so he said try back next week. grrrrrrr. but anyways im going with 90% chance its your tires. LIke I said mine isnt hardly that bad at 55 and 65 but at 60 it goes wild lol. weird I know. Zach

 

thx for any and all help man i appreciate it, but yeah they vibrate wildly i just need new tires.
