I have a wobble in the front end of my jeep.
There are a few things that may be worn in the steering system. The most common would be the Pitman and Idler arms. These components ensure that both front wheels turn as the steering wheel is turned. If these components fail, the steering gets loose and the vehicle will "walk" and need constant over adjusting when driving. The alignment is most likely out of tolerance as well. I suggest taking your Jeep to an alignment / tire shop. Most will perform free alignment checks as well as a quick "shakedown" of the steering and suspension in order to find any issues that may need addressed before an alignment can take place.
