I have a 57 with stock drivetrain and suspension. I have Firestone radials that have less than 5,000 miles on them. 235 with 3 speed. Truck gets a vibration at 60 miles an hour. Today I passed a car at about 65 -68 she really shook. Up to 58 miles an hour it is just fine. I do have plenty of peddle left at 60. Any ideas? I have bought new u joints as I thought that might be it, just haven't had a chance to replace them yet. I did replace all four shocks, and man does it handle a lot better. Shocks were really worn out.
