Front end popping
 

Hey guys I just recently purchased this truck have lifted it and done a few other things. But just recently I took it offroading but, when I came back on the road switched to 2 wheel drive I noticed a clicking in the front its not speed dependent and does it constantly. I wanted to see if it did it in 4 wheel drive but figured I would ask here first. Sorry forgot to say its a 99 GMC Suburban 2500
