Ok, When Ever I brake the tires loose on dirt roads, or anything like it, I SOMETIMES hear a CLUNK noise, and it kinda scares me. I could never figure out what it was until a friend of mine said today that it might be axle wrap, is this possible?

 

Anyone??

 

Anti-lock braking systems make a weird clunking/popping noise sometimes during activation. The fact that you are talking about loose traction situations would suggest to me that your truck is engaging the abs during braking. Which also if the noise is really loud there could be a bad abs sensor or something causing the abs to not operate properly.
