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!

 

Start with the tires first. Could be uneven wear, or they need re-balancing.

 

Balancing the tires would be my first step.
