What year is the jeep, how many miles, etc. Need more info.
Based on what you've said, if there's no play your bushings are probably okay. It is most likely due to your front shocks sagging, these trucks are known for that happening eventually. I'd recommend replacing the front coilovers. If you aren't able to do it soon, get your alignment fixed (this will straighten out the front wheels) otherwise you will wear your tires unevenly.
Inspect your bushings, I just replaced all of mine in the lower control arms - pain in the @$$. The only ones that were really bad were the lower clevis bushing - when the jeep was sitting on the ground, you could see the bolt wasn't centered in the bushing anymore, it was fairly pounded out - unfortunately, it's also the more difficult one to replace. Most people just recommend replacing the lower control arms as you can buy them as an assembly with bushings already installed. But then you're looking at $300 per side at least, as apposed to $150 for all the bushings (that's the high quality MOOG bushings, too.) - but it is alot more work pressing the bushings out. As far as the upper control arms, not worth replacing just the bushings, I'd recommend replacing the whole control arms with the JBA aftermarket ones - they come with new bushings, replaceable MOOG balljoints, and they correct a problem with the ball joint position on the factory arms. For the price, you can't go wrong. Check them out here.
It doesn't sounds like bushings are your problem, though.
