Brake release then pop

Hello I’m a DIYer and have a question that someone could point me in the right direction.2005 Chevy Silverado 1500 4wd.. When I come to a complete stop, then give it the gas there is a pop/clunk sound,if I ease off ,not so much. I put the front on jack stands,because I thought it might be ball joints,everything tight..Wheel bearings ok, sounds like it’s comming from the front end.any thoughts on what else I could check?

How did you test the ball joints? On that truck, you want to jack up underneath the lower control arm to unload the joint, then use a pry-bar underneath the tire to lift the joint and check for movement.

Also I know you said it sounds like front end but maybe check the u joint in the drive shaft as well they will pop on acceleration

Brake pad/caliper moving in the guide bracket ? Did you check the propellor shaft joints ?

Do I need to take the weight off of the 2 rear tires to properly check this?

I did not. Thanks I will check

I did unload the weight. Then checked for play everything ok on ball joints.

I did not check pad /caliber I will do that.
