My 1990 f150 steers much better now than when I got it couldn't even make a right turn.
At low speeds around town it's ok got new tires recently but on freeway at 65 I find it fatiguing to keep straight and in my lane. It's not terrible but was wondering if this could be fixed to make it easier on freeway to steer?

 

It doesn't wander just play in steering wheel makes it difficult to drive at high speeds, I feel like I'm over steering to keep it on the road

 

How is it better than when you got it i.e. what did you do to make it better? Have you checked for worn parts including the intermediate steering shaft?

 

My 88 F150 is the same. I think it's time for a new steering box.

 

You could tighten your steering box but don't tighten it too much. My buddy helped me do that and it helped with the loose steering but honestly I think I need new suspension bushings. I looked under there one day and I guess it's the pittman arm bushings but they are way old looking and cracked.

 

When I got the truck the frame was broken and the steering box was twisted frame was welded. Also the steering wheel was spinning in shaft stripped out bolt so I needed to replace steering wheel with after market and kit then wheel and tires where aligned. Have not done anything to steering box is that a good place to start? Also new correct size tires make it steer much better

 

Have someone turn the steering wheel left and right. Look at the joints on the intermediate shaft and also check to see how much input it takes before the pitman arm moves.

Choate - there aren't any bushings on a pitman arm. Are you looking at the radius arm bushings or maybe the pivot bushings?

 

Thanks will look into checking it out. I was also wondering about having bad suspension or shocks today on freeway at 65 I almost felt like it was floating weird feeling???

 

If you don't know how old the shocks are or how many miles are on them it couldn't hurt to replace them. Your shouldn't keep bouncing after hitting a bump.

 

In my experience, with my 88 F150 4X4, the intermediate shaft was the biggest culprit. The shaft telescopes with a the lower portion fitting inside the upper and that interface gets loose. Watch the shaft while turning the steering wheel and I'm sure you'll see significant movement of the upper shaft before the lower portion moves. I believe Borgeson makes one that may be less costly than a FOMOCO replacement. That new shaft took a lot of vagueness out of my steering.
