How do you change spark plugs on a 2004 Chevy Silverado Z71?

With a 5/8 inch spark plug socket and a rachet. simply pull the wire off of the plug, change the plug , then push the wire back onto the plug.

I hate to even ask, why you would ask,I don't want to be
sarcastic, but you surely can see them & working on
spark plugs, on what I assume is a V6 or V8 chevy ,has
been the same for 50 years !

So what is the problem?
Not enough tools,clearance issues
