Drivetrain noises

I have a 99 wrangler sport with a four inch lift and 35s on it. I haven't had it very long and it makes a lot of pops and clunks when I'm backing up or turn and I'm not Turing sharply just wanted to know how normal this is. Any help would be awesome

Is make sure those tires aren't rubbing the front bumper or fenders. Start there and also popping n clunking while turning is look into ball joints or just bad suspension parts in general. And as far as backing up id look into the u joints on the driveshafts. They can make some noises on ya.

Mine as well clunks n pops too. But another common problem is those stab links that connect to the drag link can still be connected but inside of the little boot its kinda like a ball joint they separate and clunk against eachother when hitting bumps n turning n what not. Best way to check is put a floor jack under it jack it up to raise it apart n slowly let it back down to see n hear for the noises.

check to make sure all suspensions and steering end links (no matter what kind of link, johnny joint, etc) to make sure all bolts are tight, they can become loose just from common driving. this same exact scenario occured after an offroading trip i and some friends took to rausch creek...the axle side bolt in the lower control arm on the front axle of my friends tj came loose and as a result, the control arm clunked around a bit from the loose bolt only when taking turns and stopping without stopping hard...just enough for the arm to move a bit. have a friend watch all the components while you roll forward and back...thats how we found what it was.

good luck
