hey guys im new to the forums and i recently got a 94 f150 xlt 4x4 reg cab shortbed straight six motor. the truck has a 6inch susp lft (superlift) and a 3inch body lift. 36.5s, now when im on the highway the truck is all over the road, the steering wheel is upside down. and with the truck off, if u move the steering wheel u can see the frame moving bad, idk whats wrong if u hit a bump in the road while driving the truck will go its on way if ur not holding the steering wheel strong. idk what the problem can be and i think the p;itman arm isnt long enough because it looks stock and doesnt loook like anything with the front end was messed with when the lift was done just bigger springs and shocks any help would be great thanks

 

that truck is jacked.
the frame moves cuz the rivets that hold the cross member and the steering gear box are worn and rattling around. GET IT FIXED!!!!! i know form experience when mine busted going around a corner and about sent the engine thru the hood.

 

whats the best way to fix it just weld it? figures id get shafted what would help the reason its all over the road and worse when i hit bumps

 

GMCtrucknut has a thread on here about his frame breaking, and therenwas one about bracing the front frame with an additional crossmember.

It sounds like you might be right about the pitman arm.
could you get some pictures of the pitman arm and drop brackets for the lift.

it could be your alignment is completely assed up, plus wiggly frame. Check for cracking around the mount for the steering box.

 

i kill you lol
