Wish I could. The weather is freezing and raining. That's and I don't know if I even have the tools to do it. All that and the lack of daylight is killing me.

 

If checking it yourself is not an option, maybe you should take it to the person who installed the spacers or a shop who can check the front end for you. Most likely its something minor like a sway bar link but its better to be safe than sorry.

 

I had this exact same sound happen to me. Turns out it was a loose front swaybar link. Lay under the jeep and bounce the front end up and down by the bumper and look for moving components. If you can see anything move tighten everything you can get a wrench on. Good luck.
