Adjust it by throwing it in the trash, cause that's all it is. New tie rod ends won't last a year even with road miles.
I'd go with the recommendation by 4.3l XJ and get that steering system by RE. It will be the most reliable and will require minimal work to install since its bolt in.
*side note, not trying to be a dick, but I had a very similar setup and constantly wore out rod ends, it caused many issues with good control over the road. Now that I have the steinjager setup, I have no more dead spots in the range of steering.
As stated above, id recommend keeping it simple though and go with the RE kit. Also, im curious to know if you have a drop pitman arm or not, some measuring might be in order for you to figure that out. Unless the PO of the jeep could tell ya.
