Check the spring pins they are probably worn
-
Maybe the bushings, king pin, but I would say your best bet is in the springs

Get a helper...turn your wheel all the way left...and all the way right...
Your drag link/pitman joint may be hitting your frame...or your tires may be rubbing your drag link or your hitting your wheelstops..if you have a ross youll need to reset your poppets...if a shepard... need a long thin screwdriver. If its a ross gearbox..get someone thats done it before to help you...sheppards are easy... -
I had this similar problem in my Freightliner Century. The cause was the U-bolts on the springs gets ever-so-loose, and it allows enough that on a turn, it moves a fraction of a fraction of an inch, but enough to hear it. Get it aligned, torque your U-Bolts, and the sound goes away. That was my problem.
Bouncing down a highway 100,000-plus miles a year can loosen things.Jaybx Thanks this. -
Grease your king pins. Anytime I get lazy, the first sign is the popping sound in turns

Big_D409 Thanks this.

Could be a broken front leaf spring....although I would describe that as a clunk.

Just for kicks and giggles try greasing the fifth wheel. A dry fifth wheel can cause strange frontend noises in a tight turn along with helping the front steers wear out.

Leaf spring pins/bushings are worn
