Ok, When i got it, it had 31/ 10.5x15 tires on it. Recently as y'all know i body lifted it and put 35/ 12.5x16 tires and rims on it. At 50 miles anhour on the speedo (i dunno what the real speed is cuz of tire size) The sumbitch starts to shake real bad like shes gonna come apart. The tiress came off my buddys truck and his didnt do it. I looked for missing weights but all are there. So....whats the deal? Some one at work mentioned abour the steering arm may be loose or bad? How do you check that? Any help appreciated.
