If you have been offroading & your steering is now crooked where it wasn't before, look to see if something is bent before just straightening it using the adjustment link on the drag link.
That the Jeep wants to go left when the steering wheel is held straight could mean the drag link (the part that connects between the steering box's Pitman arm and the knuckle on the passenger-side) is bent. Or it could be a bent tie rod. I doubt it's the track bar that is bent since that would force the Jeep towards the right when the steering wheel is held straight.
If nothing is bent, the steering wheel is straightened so it drives more towards the right by slightly lengthening the short link on the drag link until the steering is straight. The trackbar is lengthened by turning its adjustment link so that the front of the link is moved downward.
Rotate the adjustment link just a tad between short test-drives up & down your street. No need to tighten the link's clamping nuts & bolts between each of the short test drives. Just make sure both clamping bolts are securely tightened once the steering wheel is straight again.
