Look for some hack lift work under the front.Any successful attempt to lift the front will result in some bump steer if not done right. after about 2 inches lift you'll start noticing it and a 4 inch lift with out attending to the track bar and pitman arm, is going to bump steer noticeable. Also aggravated by larger tires and worn steering and suspension components.

 

 

Post a pic of your front end steering links n mounts - track bar, pitman arm, and track bar bracket.

Lift measurements? A 4-inch lift will measure about 25 inches from the front axle centerline vertically to the upper fender arch. Post up yours.

 

Drag link should be kinda sorta close to level just sitting, if anything it should be slightly high at the box. The panhard ideally should be close to level as well, but they weren't even with stock suspension. If it has more than just a couple inches it should have some drop brackets added to level it out as much as you can.....

 

And just for clarification, the panhard and track bar are just different names for the same part. so the basic advise is to look under the front with it setting on the ground and see the track (panhard) bar and the tierod close to parallel to the ground

 

 

 

The steering stabilizer shock mounts (Left side) are moused up.....

How bad are the shocks?

Looks like that drop pitman arm is for a 4" - 6" lift

 

 

When you rock the steering wheel back and forth sitting still, does the front of the truck also move side to side a little? That would mean track bar bushings. From the age and condition, I think all the bushings, tie rod ends and other components are in need of a thorough inspection. It's nice they put the pitman arm on though, one piece you won't need.

 

 

Look at the nice, shiny rod in your picture...to the moused up rubber washers and cups.

What's wrong with this picture?

 

 

Not "wrong" in the mount department, so much as slightly off due to the dropped pitman arm. They normally sit roughly level from the factory, but dropping only one end puts it at a funky angle.
Most people don't bother, but creating some sort of a spacer or special bracket for the frame end (passenger side) of the shock would level it back out.

Definitely do "the test" like Willowbilly was saying, to find out what all is loose under there. If the trackbar drop bracket was not welded after installation it's probably flexing more than it should. And it only takes a tiny amount of movement in the trackbar to lead to noticeable wandering or "loose" feeling steering.

Pay particular attention to the passenger side/lower trackbar mount at the axle. They tended to wobble out their mount to the point that no matter how good the bushing is, the mount stud itself moves side to side.
So much so, that they make kits to replace it with a more robust setup.

By "the test" I mean where a helper racks the steering wheel back and forth about a half a turn in each direction while you hang out under the truck to see what moves when it shouldn't. They do this continuously until you've checked literally everything from your steering column shaft, steering box mounting on the frame, trackbar mounts, rod ends and even wheels and wheel bearings.

With the full weight of the truck on the ground and the monsterous power of a power steering system pushing against it, every loose piece will become known.
And when you're done up front, you can even go back and look at all the stuff in the back!
Even the back springs and stuff will flex out while the steering system is being manipulated like that.

Fun stuff.
