I know they are el cheapo Ranchos, but my truck doesn't feel planted to the road. I'm having a difficult time keeping it in the lane, it feels like it wants to wander. I've had four F150s, two had the FX4 package, two without. Both trucks with the shocks made the ride feel floaty.

I had a 15 Lariat and the only differences between that truck and my current one is that truck had Goodyear, this one of course the Hankooks. The other truck didn't have the FX4, and this one does. Both trucks rode like night and day comparing the two.

Could this whole problem be shocks? I seriously doubt the tires, seems to me the Hankooks are some of the best rated AT tires out there. Any opinions?

 

My truck has the FX4 and and feels just fine. It feels the same before and after the level. I don't know if shocks will cause what you are describing. Start with the simplest thing first and check tire pressure.

 

I keep a close eye on that, as I tow not everyday but often. Tires are at 37 all the way around. Tried them at the recommended 35 too, just to see. It was no difference in ride/handling.

 

Wandering is more commonly caused by your tires tracking. I think the suspension is unlikely the cause. However, I will say that the rear end liked to hop around when going over the small ruts in the road caused by the cold. Is that what you are experiencing? I've found that it has gotten significantly better once I added my topper. Seems a little extra weight in the rear solved it. YMMV.

 

It could absolutly be tires although never experienced on my pick up, our work trucks only seem to like goodyears any other tire it's almost impossible to keep the trucks going straight down the road. To be fair work truck is a F450 utility bucket truck with dual rear

 

Wouldn't a bad alignment cause this as well? I'd get the dealership to check the alignment and give you the printout of the actual specs.
