I have 2004 for ranger fx4, at 60 mph I start feeling vibrations on the steering wheel and they get much worse going past 70 mph (shaking starts feeling like a wobble) replaced all 4 shocks and got new sway bar links and also replaced my lower ball joints…. Any advice on what the problem might be Thanks!

 

Could be flat spot on a front tyre or a leaking wheel carcass making bump/s under tread.

 

Maybe lost a balancing weight off a tire.

 

Swap the wheels front to back. If it still happens than its not the wheels or tires .
