Steering ?

So long story short after the coil over install the bump stops on the front axle didn’t line up the axle rolled back a bit . I finally got around to checking the castor was at 13.7 degrees adjusted it back to around 9.2 degrees. Bump stops and driveline is straight.
So now the steering wheel is off center to the left and there is no more adjustment in the drag link to center it back up . Any thoughts .
 
It’s a stretch but does the wheel take the same amount of turns to get the wheel from center to lock in each direction?

Is it even possible to set the drag link if the wheel is a full revolution (to the right) from center? If so the pitman arm could be cheated towards the passenger side effectively making the drag link seem too long.

Is the steering box stock? I haven’t had a pitman arm off of one of these but is it possible to install it a few teeth off, or are they “keyed” preventing an off center install.

Is your track bar adjusted? The axle would shift towards the driver side as lift increases. Even if the axle is centered perfectly you may be able to sacrifice a little to get the wheel closer to center by adjusting it.

That’s all my little brain can come up with besides the possibility your MC steering isn’t correct like @Disciple Off Road said
 
PSC box with hydraulic assist. I’ll double check track bar. I know since the addition of the PSC I lost turning radius to left.
just found it odd that a adjustment in camber changed the steering that much .

if you lost turning radius, sounds like the ram mount may need to be adjusted on the tie rod or the ram stroke is too short.

Have you measured the steering travel distance side to side to make sure the ram is the correct length, and mount hasn't moved out of proper location (drag link removed at the knuckle).

Also with the drag link connected, ram released, count the number of turns from lock to lock to check if it's equal and pitman is keyed correctlt (as mentioned by @CalSgt)
 
When the caster is changed, the geometry of the drag link also changes which would change steering wheel angle.

If I recall, caster should be set to no more than 6 degrees positive. Positive caster stabilizes steering and gives it its self centering. Excessive caster impacts other steering geometry such as steering radius.

Check to see if the axle is centered in the frame left to right. Then check to see if it’s centered fore and aft, that is, check to see if one side of the axle is more fore or aft than the other. A cockeyed axle will play havoc with steering geometry.

Check to see if anything is binding. It’s not uncommon for the tie rod to rub against the diff cover while turning. The steering could be binding in a number of locations.

If the hydraulic ram isn’t located correctly, it will reduce steering radius in one direction. If ram stroke is too short, that will also reduce steering radius.

It’s been parked for the most part since PSC was installed between moving and AZ heat I’ve been busy. I reset the caster last weekend and noticed the steering . If I remember Dynatrac has more caster built in. Pretty sure the drag link and track bar are bottomed out. I’ll dig in some more this weekend and see
