yea there all engine mounted and gear driven but you have the square style then most of them had a single douple lip seal that is no longer serviced and you just replace it with two single lip seals

Remove the front grill and look at the linkage. A couple of things could be wrong. Simplest would be that the small turnbuckle is worn or out of adjustment.
The next thing to look at is the arm that the draglink mounts to see if it turns independent (very slight movement) from the arm that the cylinder mounts. The upper arm is supposed to pivot on the lower arm, but it often rusts and freezes.
Check for just plain wornout pivots and linkage as the more slop, the less the steering valve can sense and open the steering valve tonassist in steering.
Last, the hydraulic cylinder could be leaking internally.
