noise in suspension

I have a 2001 s-10 xtreme which i just bagged with the airride tech coolride front kit and airbar rear kit. My question is, whenever i go in reverse, i hear a clicking noise, i thought it was in the rear but i think it may now be in the front, i am not sure though. I just greased the front end, everything is tight, and i have only put about a thousand miles on the new suspension. I am just wondering if this is normal or i should be conserned

Never really heard of that problem before
