03 popping noise front end z71 1500 binding up??

[Seadoojetski]

Any ideas what this could be. I put it in reverse ( no gas ) and then drive. I have someone recording it outside the truck walking with it. No turning just going reverse then foward not stepping on the gas

Is foot on the brake?
Does it do it when all wheels off the ground?

Could be bad Ujoint(s)

No foot on brakes , haven’t put it up in the air

 

[ygmn]

what is sound when foot on the brake?

 

[Seadoojetski]

Same , no change

sO when you hold brake and change from R to F and back...
Does the truck rock a bit or anything move or you just hear noise...

If you just hear noise then it is from flywheel to TRANNY
