Loud clicking under hood in front of driver

I beleive this is normal and can not find how to search it on youtube. By first Taco did it when I had wheel slip. I am wanting to off road more and need to understand what is happening. Makes the clicking noise even when I roll backwards in gear on a hill.

Any video or clear examples would be great.

Know of any videos that shows this happening?

 

Best I could find: https://www.youtube.com/watch?v=56DugwWHrAk

 

Question... where did the people who make videos that answer questions learn it from?
Other videos?
Reading?
Learn by doing?

Point is, if everyone learns keeps learning by youtube videos, eventually there will be nobody to make new videos.

 

Thanks alot. Thats the sound.
My last taco was a sport and had none of these options.
Thanks for your help.

 

No worries, it happened to me the first week I got my truck (used) and I thought I bought something that was falling apart.
