Question about 1989 Jeep Cherokee
This could be multiple things. When you say it wobbles, does it happen at a certain speed, all the time, or??
If this happens at highway speeds, I would say that this is called "death wobble" and it is typical of lifted Cherokees. This problem is indicative of a worn front end and will require replacement of one or more steering components.
I can tell you what I did to mine. I replaced the tracking bar....rather easy but does require some muscle to loosen the bolts. I also replaced a VERY worn lower control arm.
What I would recommend is, put the front of the Jeep on jackstands and while someone turns the steering wheel from side to side (where you hit resistance back to where you hit resistance) you need to be underneath, carefully watching each component for play/movement. If you find play in any parts, remember it........write it down, mark it, whatever you need to do to remember it. You also need to notice if the front axle is moving and if so, where the movement is coming from. Once you do this, you will know what parts are bad and need replaced.
You may also need to adjust your steering box. This involves removing the electric fan on the driver's side of the radiator. 2 bolts at the top and unplugging a wire will accomplish this. You will then see your steering box. There is a stud at the top that has a nut around it. Loosen the nut (a 15 if I recall correctly) and with an allen wrench, tighten the stud down until you meet resistance. Turn the steering wheel back and forth and do it again and then tighten the nut. Now....if you go too far, the Jeep will be a bear to drive. This is simple to fix...just loosen the nut and stud and then retighten the nut.
The next thing to check is your tires. How are they wearing? Are they evenly worn or do they show "Cupping" of the tread? If they do, you need to replace them or at least move them to the back. Balancing them would not be a waste of money.
This is not everything that could be wrong, but is a place to start. If this doesn't help you, then let me know or take it to a reputable tire shop and have them give you a diagnosis. This doesn't mean that you have to have them fix it, but depending on your mechanical skills, it may be a good way to get things done.
When you get this all fixed, get a front end alignment.

I would also check the Upper and lower ball joints. Just jack one wheel up and place a pry bar under it at the 6o'clock location. Lift up and down and have someone look at the upper or lower ball joints. if there is more than 1/4" play there is room to replace the joint. They are replaced in pairs. While the wheel is off the ground grab it at the 9o'clock and 3o'clock locations with the left and right hand respectively. Move left to right. If the whel has excessive play it is the tie rod that requires replacement.
