Snap a few pictures of the front suspension and post them up, and we will most likely be able to tell if there is anything that is not stock. First, how much air is in your tires? You should also do a dry steering test like this:
Do a dry steering test by having someone sit in your Jeep (with the tires on the ground) and continuously turn the steering wheel back and forth from about the 11 to 1 position while you lay under the front end and watch
for any lateral play in any steering or suspension joints. Check both track bar ends, the tie rod and drag link ends.
Although rotational movement in the tie rod and drag link is normal and necessary, there should be no end movement at all in the joints. There also should be no movement in the track bar ends.
You can also jack each front wheel slightly off the ground and with a small pry bar under the tire, see if there's any vertical play indicating bad ball joints.
