Hello,

I have a 2004 FX4 5.4L with about 78500miles and am having an issue. I was driving home yesterday on the freeway and about half way home my truck started to get really bumpy. It felt like the truck had no suspension and now i am feeling every bump in the road. My truck probably does need new shocks, but what was wierd is that the truck was riding smooth and then all of a sudden it got bumpy and has been like that ever since. Could it be the suspension? Or could it be drivetrain issue? I think its wierd how it just suddenly happened. I am going to check the suspension and drivetrain tonight. Any advise?

 

Is it bumpy like your feeling bumps in the road or shaking like a drivetrain shake/bucking? It could be bucking from a bad cop, a bad spark plug, or even the tranny if it isn't shifting smoothly. It could also be that the rear shocks have leaked out and aren't working any.
