Excursion front end, steering issue

[1quick]

So I've replaced everything on the front end of the excursion over the last year except for the steering box, ball joints and pitman arm, the steering will be fine for weeks then all of a sudden it will start jerking the wheel to the left, sometimes back and fourth like a death wobble, I had planned on replacing the steering box this fall winter, but it also needs the lines and power steering pump they alll leak, when I bought the truck everything was pretty bad I've tightened up the steering box probably more than I should have to get all the slop out plus all the new parts, is this something balljoints could cause or am I looking at the steering box, I'd like to get a good aftermarket unit but don't know a ton about the hd trucks

No one familiar with these?

is it 4wd? does the truck have a steering stabilizer? check the track bar bushings too.

the balljoints can cause this issue too, did you check those? when you jack the front end of the truck up you put a pry-bar between the tire and ground then push up on the tire. you usually won't see ball joint play doing a standard shakedown

Ended up being a seized driver side axel ujoint, I'll know for sure after I drive it to work tonight but took a quick 5 mile driver after replacing it and all was good, it was toast though would move one way but totally seized the other

At least it was a simple fix.

Putting a new steering gear box in it today then all it will need is an alignment and tires and it will be ready for winter
